Ipecac or ipecacuanha consists of the dried rhizome and roots of "Cephaelis ipecacuanha".

The medical virtues of ipecac are almost entirely due to the action of its alkaloids-emetine and cephaline. Till today, emetine remains one of the best drugs for treating amoebic liver abscess. It has a direct action on the trophozoites.

Its greater concentration and duration of action in the liver as compared to that in the intestinal wall explains its high efficacy in amoebic liver abscess and also its low parasitic cure rate for intestinal amoebiasis.

The drug is detoxicated and eliminated slowly. It may, therefore, produce cumulative effects. In man, emetine poisoning is characterized by muscular tremors, weakness and pain in the extremities which tend to persist until drug administration is stopped. Gastro-intestinal symptoms include nausea, vomiting and bloody diarrhoea. The latter may be mistaken for a recurrence of amoebic dysentery.

Many clinicians fear the occurrence of cardiac toxicity due to this drug and hence avoid using it. Serious cardiac toxicity, however, is rare. Both recovered with the treatment for heart failure and withdrawal of emetine. One patient who was given fifteen injections of emetine in a dose of 60 mgm per day, died.

Overdosage of emetine produces focal necrosis of cardiac muscle resulting in cardiac failure and sudden death.

Emetine, like digitalis may produce mild ST and T wave changes in the electrocardiogram which does not necessarily mean serious toxicity. In fact, they are encountered, though less commonly, after the use of chloroquine and metronidazole as well.

Toxic effects on the myocardium have been described even in doses generally considered safe. These are rise in pulse rate, fall in systolic blood pressure and ST-T changes in the electrocardiogram.

The other rare E.C.G. changes include deformity of QRS complexes, prolongation of PR interval, atrial premature beats, and atrial tachycardia. In adults, fatal cases have been reported with a total dose of 0.6 G. or less. The incidence of toxic heart damage greatly increases in patients with anaemia.

In patients having myocardial disease or marked hypertension, emetine can be used for amoebic liver abscess, as the benefits from it may outweigh possible hazards. This situation is unlikely to arise these days, as equally good alternative drugs like metronidazole are available. Patients receiving emetine should be monitored for changes in pulse, blood pressure and electrocardiography. Absolute bed rest during and several days after emetine therapy has been recommended, although we have often seen patients in whom no untoward reactions have occurred in spite of neglecting the above precaution.

Theoretically the use of emetine in children is not advised. However, in practice it has been used as discussed elsewhere. It should not be administered during pregnancy unless absolutely necessary.

Although emetine is undeniably moderately toxic, the risk of using it would be worth accepting in such a serious illness were it not for the fact that less toxic drugs like chloroquine and metronidazole are now available.

In practice, emetine still produces a more dramatic clinical response thanchloroquine or metronidazole. This point would score in favour of emetine in places where facilities for a proper diagnosis are not available and a therapeutic test remains as the only weapon with a practitioner.

Emetine should always be given deep intramuscularly or deep subcutaneously but never intravenously. The total dose in amoebic liver abscess should not exceed 650 mg or 10 mg/kg. This should be given over a period of 10 days in a dose of 6G65 mg. daily. A relapse rate of 7% follows one such course. Therefore, the treatment could be repeated after a period of 2–6 weeks. Of late such a need does not arise, as drug combinations are commonly used. When parenteral emetine is combined with oral chloroquine or two courses of emetine are given, the relapse rate can be brought down to 1 percent.

It is a synthetic compound developed by Osbond "et al." and Brossi "et al." in 1959. It is as effective as emetine in its amoebicidal properties. Given parenterally dehydroemetine is surprisingly painless. Oral tablets have been introduced. But for some reason, these tablets have not become popular. A high cure rate can be obtained with this drug. Compared to emetine, its concentration in the heart is less. Electrocardiographic changes are not seen so often. When present, they are more transient than with emetine.

Dehydroemetine is excreted by the kidneys, heart and the other organs more rapidly than emetine. Therefore, a daily dose of 1.25 mg or 1.5 mg/kg body weight is necessary. The total daily dose should not exceed 90 mg. The course should not be repeated in less than 14 days.

People with AIDS are given macrolide antibiotics such as azithromycin for prophylactic treatment.

People with HIV infection and less than 50 CD4+ T-lymphocytes/uL should be administered prophylaxis against MAC. Prophylaxis should be continued for the patient's lifetime unless multiple drug therapy for MAC becomes necessary because of the development of MAC disease.

Clinicians must weigh the potential benefits of MAC prophylaxis against the potential for toxicities and drug interactions, the cost, the potential to produce resistance in a community with a high rate of tuberculosis, and the possibility that the addition of another drug to the medical regimen may adversely affect patients' compliance with treatment. Because of these concerns, therefore, in some situations rifabutin prophylaxis should not be administered.

Before prophylaxis is administered, patients should be assessed to ensure that they do not have active disease due to MAC, M. tuberculosis, or any other mycobacterial species. This assessment may include a chest radiograph and tuberculin skin test.

Rifabutin, by mouth daily, is recommended for the people's lifetime unless disseminated MAC develops, which would then require multiple drug therapy. Although other drugs, such as azithromycin and clarithromycin, have laboratory and clinical activity against MAC, none has been shown in a prospective, controlled trial to be effective and safe for prophylaxis. Thus, in the absence of data, no other regimen can be recommended at this time.The 300-mg dose of rifabutin has been well tolerated. Adverse effects included neutropenia, thrombocytopenia, rash, and gastrointestinal disturbances.

Postinfection treatment involves a combination of antituberculosis antibiotics, including rifampicin, rifabutin, ciprofloxacin, amikacin, ethambutol, streptomycin, clarithromycin or azithromycin.

NTM infections are usually treated with a three-drug regimen of either clarithromycin or azithromycin, plus rifampicin and ethambutol. Treatment typically lasts at least 12 months.

Although studies have not yet identified an optimal regimen or confirmed that any therapeutic regimen produces sustained clinical benefit for patients with disseminated MAC, the Task Force concluded that the available information indicated the need for treatment of disseminated MAC. The Public Health Service therefore recommends that regimens be based on the following principles:

- Treatment regimens outside a clinical trial should include at least two agents.

- Every regimen should contain either azithromycin or clarithromycin; many experts prefer ethambutol as a second drug. Many clinicians have added one or more of the following as second, third, or fourth agents: clofazimine, rifabutin, rifampin, ciprofloxacin, and in some situations amikacin. Isoniazid and pyrazinamide are not effective for the therapy of MAC.

- Therapy should continue for the lifetime of the patient if clinical and microbiologic improvement is observed.

Clinical manifestations of disseminated MAC—such as fever, weight loss, and night sweats—should be monitored several times during the initial weeks of therapy. Microbiologic response, as assessed by blood culture every 4 weeks during initial therapy, can also be helpful in interpreting the efficacy of a therapeutic regimen.Most patients who ultimately respond show substantial clinical improvement in the first 4–6 weeks of therapy. Elimination of the organisms from blood cultures may take somewhat longer, often requiring 4–12 weeks.

The treatment of primary immunodeficiencies depends foremost on the nature of the abnormality. Somatic treatment of primarily genetic defects is in its infancy. Most treatment is therefore passive and palliative, and falls into two modalities: managing infections and boosting the immune system.

Reduction of exposure to pathogens may be recommended, and in many situations prophylactic antibiotics or antivirals may be advised.

In the case of humoral immune deficiency, immunoglobulin replacement therapy in the form of intravenous immunoglobulin (IVIG) or subcutaneous immunoglobulin (SCIG) may be available.

In cases of autoimmune disorders, immunosuppression therapies like corticosteroids may be prescribed.

Current HAART options are combinations (or "cocktails") consisting of at least three medications belonging to at least two types, or "classes," of antiretroviral agents. Initially treatment is typically a non-nucleoside reverse transcriptase inhibitor (NNRTI) plus two nucleoside analog reverse transcriptase inhibitors (NRTIs). Typical NRTIs include: zidovudine (AZT) or tenofovir (TDF) and lamivudine (3TC) or emtricitabine (FTC). Combinations of agents which include protease inhibitors (PI) are used if the above regimen loses effectiveness.

The World Health Organization and United States recommends antiretrovirals in people of all ages including pregnant women as soon as the diagnosis is made regardless of CD4 count. Once treatment is begun it is recommended that it is continued without breaks or "holidays". Many people are diagnosed only after treatment ideally should have begun. The desired outcome of treatment is a long term plasma HIV-RNA count below 50 copies/mL. Levels to determine if treatment is effective are initially recommended after four weeks and once levels fall below 50 copies/mL checks every three to six months are typically adequate. Inadequate control is deemed to be greater than 400 copies/mL. Based on these criteria treatment is effective in more than 95% of people during the first year.

Benefits of treatment include a decreased risk of progression to AIDS and a decreased risk of death. In the developing world treatment also improves physical and mental health. With treatment there is a 70% reduced risk of acquiring tuberculosis. Additional benefits include a decreased risk of transmission of the disease to sexual partners and a decrease in mother-to-child transmission. The effectiveness of treatment depends to a large part on compliance. Reasons for non-adherence include poor access to medical care, inadequate social supports, mental illness and drug abuse. The complexity of treatment regimens (due to pill numbers and dosing frequency) and adverse effects may reduce adherence. Even though cost is an important issue with some medications, 47% of those who needed them were taking them in low and middle income countries as of 2010 and the rate of adherence is similar in low-income and high-income countries.

Specific adverse events are related to the antiretroviral agent taken. Some relatively common adverse events include: lipodystrophy syndrome, dyslipidemia, and diabetes mellitus, especially with protease inhibitors. Other common symptoms include diarrhea, and an increased risk of cardiovascular disease. Newer recommended treatments are associated with fewer adverse effects. Certain medications may be associated with birth defects and therefore may be unsuitable for women hoping to have children.

Treatment recommendations for children are somewhat different from those for adults. The World Health Organization recommends treating all children less than 5 years of age; children above 5 are treated like adults. The United States guidelines recommend treating all children less than 12 months of age and all those with HIV RNA counts greater than 100,000 copies/mL between one year and five years of age.

Bone marrow transplant may be possible for Severe Combined Immune Deficiency and other severe immunodeficiences.

Virus-specific T-Lymphocytes (VST) therapy is used for patients who have received hematopoietic stem cell transplantation that has proven to be unsuccessful. It is a treatment that has been effective in preventing and treating viral infections after HSCT. VST therapy uses active donor T-cells that are isolated from alloreactive T-cells which have proven immunity against one or more viruses. Such donor T-cells often cause acute graft-versus-host disease (GVHD), a subject of ongoing investigation. VSTs have been produced primarily by ex-vivo cultures and by the expansion of T-lymphocytes after stimulation with viral antigens. This is carried out by using donor-derived antigen-presenting cells. These new methods have reduced culture time to 10–12 days by using specific cytokines from adult donors or virus-naive cord blood. This treatment is far quicker and with a substantially higher success rate than the 3–6 months it takes to carry out HSCT on a patient diagnosed with a primary immunodeficiency. T-lymphocyte therapies are still in the experimental stage; few are even in clinical trials, none have been FDA approved, and availability in clinical practice may be years or even a decade or more away.

Extensive treatments have been used on domestic animals more than on wild animals, probably because infected domestic animals are easier to identify and treat than infected wildlife. Treatment plans and management vary across taxa because this disease tends to affect each species differently. Antifungal drugs are the first line of defense to kill the agents causing phaeohyphomycosis, but despite the significant progress made in the last two decades and a 30% increase in available antifungal drugs since 2000, many drugs are not effective against black fungi. Diseases caused black fungi are hard to treat because the fungi are very difficult to kill. This high resilience may be contributed to the presence of melanin in their cell walls. Current antifungal agents the fungi are not resistant to are posaconazole, voriconazole, and azole isavuconazole.

In 2006, a free-living Eastern box turtle, "Terrapene carolina carolina", was found with a form of phaeohyphomycosis and was brought in the Wildlife Center of Virginia. Its symptom was swelling of the right hindfoot; it was diagnosed as having chromomycosis by histopathology. The center provided a series of antimicrobial treatments and a one-month course of 1 mg itraconazole, administered orally once a day. The eastern box turtle was euthanized due to further complications and the caretakers’ belief that the turtle would not be able to survive if placed back in the wild.

A recent case of a form of phaeohyphomycosis infection was found in a dog in 2011. The Journal of the American Veterinary Medical Association published a case study in which researchers successfully managed an intracranial phaeohyphomycotic fungal granuloma in a one-year-old male Boxer dog. Veterinarians of the Department of Veterinary Clinical Sciences at Tufts University surgically removed the granuloma in the right cerebral hemisphere. The patient was treated with fluconazole for 4 months, and was followed with voriconazole for 10 months. Both are medications used to treat fungal infections. Based on magnetic resonance imaging and cerebrospinal fluid (CSF) analysis 8 months after the surgery, the male Boxer’s outcome was considered excellent.

Emphasis has been placed on how to manage this disease through careful management practices including: proper handling, preventing crowding situation with animals, and transportation. Both the animals and the environment should be treated thoroughly to hinder the spread and control the fungal infection. This is especially important since humans can also contract this disease.

Most patients suffering from KTS have epilepsy that is resistant to anti-epileptic agents. Some patients showed a partial response to treatment, but very few were able to stop their epilepsy through treatment. One case was responsive to treatment using Phenobartbital and vigabatrin which are both anti-epileptic agents. Spasticity can be treated with baclofen, but not all patients are responsive to the treatment.

In the US, approximately 60% of people with HIV use various forms of complementary or alternative medicine, even though the effectiveness of most of these therapies has not been established. There is not enough evidence to support the use of herbal medicines. There is insufficient evidence to recommend or support the use of medical cannabis to try to increase appetite or weight gain.

The medications prescribed for acute toxoplasmosis are the following:

- Pyrimethamine — an antimalarial medication

- Sulfadiazine — an antibiotic used in combination with pyrimethamine to treat toxoplasmosis

- Combination therapy is usually given with folic acid supplements to reduce incidence of thrombocytopaenia.

- Combination therapy is most useful in the setting of HIV.

- Clindamycin

- Spiramycin — an antibiotic used most often for pregnant women to prevent the infection of their children.

(other antibiotics, such as minocycline, have seen some use as a salvage therapy).

If infected during pregnancy, spiramycin is recommended in the first and early second trimesters while pyrimethamine/sulfadiazine and leucovorin is recommended in the late second and third trimesters.

Non-surgical therapies include:

- Shoe modifications: wearing shoes that have a wide toe box, and avoiding those with pointed toes or high heels.

- Oral nonsteroidal anti-inflammatory drugs may help in relieving the pain and inflammation.

- Injections of corticosteroid are commonly used to treat the inflammation.

- Bunionette pads placed over the affected area may help reduce pain.

- An ice pack may be applied to reduce pain and inflammation.

Surgery is often considered when pain continues for a long period with no improvement in these non-surgical therapies.

Several methods of treatment are available, mainly consisting of careful drug therapy and surgery. Glucocorticoids (such as prednisone or methylprednisolone) decrease the inflammatory response to tumor invasion and edema surrounding the tumor. Glucocorticoids are most helpful if the tumor is steroid-responsive, such as lymphomas. In addition, diuretics (such as furosemide) are used to reduce venous return to the heart which relieves the increased pressure.

In an acute setting, endovascular stenting by an interventional radiologist may provide relief of symptoms in as little as 12–24 hours with minimal risks.

Should a patient require assistance with respiration whether it be by bag/valve/mask, BiPAP, CPAP or mechanical ventilation, extreme care should be taken. Increased airway pressure will tend to further compress an already compromised SVC and reduce venous return and in turn cardiac output and cerebral and coronary blood flow. Spontaneous respiration should be allowed during endotracheal intubation until sedation allows placement of an ET tube and reduced airway pressures should be employed when possible.

In people with latent toxoplasmosis, the cysts are immune to these treatments, as the antibiotics do not reach the bradyzoites in sufficient concentration.

The medications prescribed for latent toxoplasmosis are:

- Atovaquone — an antibiotic that has been used to kill "Toxoplasma" cysts inside AIDS patients

- Clindamycin — an antibiotic that, in combination with atovaquone, seemed to optimally kill cysts in mice

Some medications that can be used for erethism are Traid and Ritalin. Methylphenidate (Ritalin) is a stimulant drug approved for therapy of attention-deficit hyperactivity disorder, postural orthostatic tachycardia syndrome and narcolepsy. It may also be prescribed for off-label use in treatment-resistant cases of lethargy, depression (mood), or neural insult.

One treatment of mercury poisoning was to admit fresh air to the patient by having him go outside daily as much as possible. Stimulants such as ammonia have also been documented to help restore pulse to a normal rhythm. For a more comprehensive reading of treatment, see Mercury poisoning, 'Treatment' section.

Penicillin is used to treat neurosyphilis; however, early diagnosis and treatment is critical. Two examples of penicillin therapies include:

- Aqueous penicillin G 3–4 million units every four hours for 10 to 14 days.

- One daily intramuscular injection and oral probenecid four times daily, both for 10 to 14 days.

Follow-up blood tests are generally performed at 3, 6, 12, 24, and 36 months to make sure the infection is gone. Lumbar punctures for CSF fluid analysis are generally performed every 6 months.

Neurosyphilis was almost at the point being unheard of in the United States after penicillin therapy was introduced. However, concurrent infection of "T. pallidum" with human immunodeficiency virus (HIV) has been found to affect the course of syphilis. Syphilis can lie dormant for 10 to 20 years before progressing to neurosyphilis, but HIV may accelerate the rate of the progress. Also, infection with HIV has been found to cause penicillin therapy to fail more often. Therefore, neurosyphilis has once again been prevalent in societies with high HIV rates and limited access to penicillin. Blood testing for syphilis was once required in order to obtain a marriage license in most U.S. states, but that requirement has been discontinued by all 50 states over recent years, also contributing to the spread of the disease.

Medical Care

- Treatment may be provided on an outpatient basis.

- Cataracts that do not regress or disappear with therapy may require hospitalization for surgical removal.

Surgical Care

- Cataracts may require surgical removal.

Consultations

- Biochemical geneticist

- Nutritionist

- Ophthalmologist

Diet

- Diet is the foundation of therapy. Elimination of lactose and galactose sources suffices for definitive therapy.

Activity

- No restriction is necessary.

(Roth MD, Karl S. 2009)

The treatment options for hypohidrosis and anhidrosis is limited. Those with hypohidrosis should avoid drugs that can aggravate the condition (see medication-causes). They should limit activities that raise the core body temperature and if exercises are to be performed, they should be supervised and be performed in a cool, sheltered and well-ventilated environment. In instances where the cause is known, treatment should be directed at the primary pathology. In autoimmune diseases, such as Sjogren syndrome and systemic sclerosis, treatment of the underlying disease using immunosuppressive drugs may lead to improvement in hypohidrosis. In neurological diseases, the primary pathology is often irreversible. In these instances, prevention of further neurological damage, such as good glycaemic control in diabetes, is the cornerstone of management. In acquired generalized anhidrosis, spontaneous remission may be observed in some cases. Numerous cases have been reported to respond effectively to systemic corticosteroids. Although an optimum dose and regime has not been established, pulse methylprednisolone (up to 1000 mg ⁄ day) has been reported to have good effect.

No cure is known for 22q11.2 deletion syndrome. Certain individual features are treatable using standard treatments. The key is to identify each of the associated features and manage each using the best available treatments.

For example, in children, it is important that the immune problems are identified early, as special precautions are required regarding blood transfusion and immunization with live vaccines. Thymus transplantation can be used to address absence of the thymus in the rare, so-called "complete" 22q11.2 deletion syndrome. Bacterial infections are treated with antibiotics. Cardiac surgery is often required for congenital heart abnormalities. Hypoparathyroidism causing hypocalcaemia often requires lifelong vitamin D and calcium supplements. Specialty clinics that provide multi-system care allow for individuals with 22q11.2 deletion syndrome to be evaluated for all of their health needs and allow for careful monitoring of the patients. An example of this type of system is the 22q Deletion Clinic at SickKids Hospital in Toronto, Canada, which provides children with 22q11 deletion syndrome ongoing support, medical care and information from a team of health care workers.

In terms of the management of T cell deficiency for those individuals with this condition the following can be applied:

- Killed vaccines should be used(not "live vaccines" in T cell deficiency)

- Bone marrow transplant

- Immunoglobulin replacement

- Antiviral therapy

- Supplemental nutrition

Most approaches to treatment over the past two decades have not shown consistent symptom improvement. Treatment approaches have included medication such as antidepressants, spinal cord stimulation, vibration therapy, acupuncture, hypnosis, and biofeedback. Reliable evidence is lacking on whether any treatment is more effective than the others.

Most treatments are not very effective. Ketamine or morphine may be useful around the time of surgery. Morphine may be helpful for longer periods of time. Evidence for gabapentin is mixed. Perineural catheters that provide local anesthetic agents have poor evidence when placed after surgery in an effort to prevent phantom limb pain.

Handling may be painful and stressful because of their poor body movement and how the bones have grown. Due to the stress, handling should be kept to a minimum.

Subungual hematomas are treated by either releasing the pressure conservatively when tolerable or by drilling a hole through the nail into the hematoma (trephining), or by removing the entire nail. Trephining is generally accomplished by using a heated instrument to pass through the nail into the blood clot. Removal of the nail is typically done when the nail itself is disrupted, a large laceration requiring suturing is suspected, or a fracture of the tip of the finger occurs. Although general anesthesia is generally not required, a digital nerve block is recommended to be performed if the nail is to be removed.

Subungual hematomas typically heal without incident, though infection or disruption of the nail (onycholysis) may occur.

A reptile with spinal osteoarthropathy does not require a large vivarium. Like all vivaria it needs to be heated according to the particular reptile's needs, with a dark hiding area (e.g. a log or dark box), normal substrate and clean water for the reptile to access. It is advisable not to have anything too high for them to climb because the reptile's ability to hold onto branches (for example) is restricted; floor space is more important. It is best not to keep them with a tank-mate (especially a healthy one), since bullying may occur.

Typically no treatment is needed. If jaundice is significant phenobarbital may be used.
