For neurosyphilis, due to the poor penetration of benzylpenicillin into the central nervous system, those affected are recommended to be given large doses of intravenous penicillin for a minimum of 10 days. If a person is allergic, ceftriaxone may be used or penicillin desensitization attempted. Other late presentations may be treated with once-weekly intramuscular benzylpenicillin for three weeks. If allergic, as in the case of early disease, doxycycline or tetracycline may be used, albeit for a longer duration. Treatment at this stage limits further progression but has only slight effect on damage which has already occurred.

One of the potential side effects of treatment is the Jarisch-Herxheimer reaction. It frequently starts within one hour and lasts for 24 hours, with symptoms of fever, muscle pains, headache, and a fast heart rate. It is caused by cytokines released by the immune system in response to lipoproteins released from rupturing syphilis bacteria.

The Jarisch-Herxheimer reaction, which is the response to the body after endotoxins are released by the death of harmful organisms in the human body, starts usually during the first day of antibiotic treatment. The reaction increases the person's body temperature, decreases the overall blood pressure (both systolic and diastolic levels), and results in leukopenia and rigors in the body. This reaction can occur during any treatment of spirochete diseases.

It is important to realize that syphilis can recur. An individual who has had the disease once, even if it has been treated, does not prevent the person from experiencing recurrence of syphilis. Individuals can be re-infected, and because syphilis sores can be hidden, it may not be obvious that the individual is infected with syphilis. In these cases, it is vital to become tested and treated immediately to reduce spread of the infection.

The most popular treatment forms for any type of syphilis uses penicillin, which has been an effective treatment used since the 1940s.

Other forms also include Benzathine penicillin, which is usually used for primary and secondary syphilis (it has no resistance to penicillin however). Benzathine penicillin is used for long acting form, and if conditions worsen, penicillin G is used for late syphilis.

Radiation (radiotherapy) is frequently used for the treatment of many cancer types, and can be highly effective. Unfortunately, it also can lead to pulmonary toxicity as a side effect.

Radiotherapists are well aware of possible pulmonary toxicity, and take a number of precautions to minimise the incidence of this side effect. There are research efforts to possibly eliminate this side effect in the future.

In the case of rape, the person can be treated prophylacticly with antibiotics.

An option for treating partners of patients (index cases) diagnosed with chlamydia or gonorrhea is patient-delivered partner therapy, which is the clinical practice of treating the sex partners of index cases by providing prescriptions or medications to the patient to take to his/her partner without the health care provider first examining the partner.

The "medical benefit-cost ratio" for the patient should be kept in mind. Medicinal drugs should not be ruled out completely right from the start just because they possibly could cause pulmonary toxicity. A number of medicinal drugs that could cause pulmonary toxicity can be life-saving for certain patients with specific diseases. For example, amiodarone falls into this category. Ideally, the pros and cons should be weighed at the start of therapy and in regular intervals thereafter, based on the available scientific/medical evidence, by an expert physician, together with an informed patient.

The CDC recommendation for chancroid is a single oral dose (1 gram) of azithromycin, or a single IM dose of ceftriaxone, or oral erythromycin for seven days.

Abscesses are drained.

"H. ducreyi" is resistant to sulfonamides, tetracyclines, penicillins, chloramphenicol, ciprofloxacin, ofloxacin, trimethoprim and aminoglycosides. Recently, several erythromycin resistant isolates have been reported.

Treatment failure is possible with HIV co-infection and extended therapy is sometimes required.

Prognosis is excellent with proper treatment. Treating sexual contacts of affected individual helps break cycle of infection.

The disease can be treated with penicillin, tetracycline (not to be used in pregnant women), azithromycin or chloramphenicol, and can be prevented through contact tracing by public health officials. A single intramuscular injection of long-acting penicillin is effective against endemic treponematoses including pinta, yaws, and bejel

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.

Researchers had hoped that nonoxynol-9, a vaginal microbicide would help decrease STI risk. Trials, however, have found it ineffective and it may put women at a higher risk of HIV infection.

If a pregnant mother is identified as being infected with syphilis, treatment can effectively prevent congenital syphilis from developing in the fetus, especially if he or she is treated before the sixteenth week of pregnancy. The fetus is at greatest risk of contracting syphilis when the mother is in the early stages of infection, but the disease can be passed at any point during pregnancy, even during delivery (if the child had not already contracted it). A woman in the secondary stage of syphilis decreases her fetus's risk of developing congenital syphilis by 98% if she receives treatment before the last month of pregnancy. An afflicted child can be treated using antibiotics much like an adult; however, any developmental symptoms are likely to be permanent.

Kassowitz’s law is an empirical observation used in context of congenital syphilis stating that the greater the duration between the infection of the mother and conception, the better is the outcome for the infant. Features of a better outcome include less chance of stillbirth and of developing congenital syphilis.

The Centers for Disease Control and Prevention recommends treating symptomatic or babies born to infected mother with unknown treatment status with procaine penicillin G, 50,000 U/kg dose IM a day in a single dose for 10 days. Treatment for these babies can vary on a case by case basis. Treatment cannot reverse any deformities, brain, or permanent tissue damage that has already occurred.

The drug of choice for the treatment of uncomplicated strongyloidiasis is ivermectin. Ivermectin does not kill the "Strongyloides" larvae, only the adult worms, therefore repeat dosing may be necessary to properly eradicate the infection. There is an auto-infective cycle of roughly two weeks in which Ivermectin should be re-administered however additional dosing may still be necessary as it will not kill "Strongyloides" in the blood or larvae deep within the bowels or diverticula. Other drugs that are effective are albendazole and thiabendazole (25 mg/kg twice daily for 5 days—400 mg maximum (generally)). All patients who are at risk of disseminated strongyloidiasis should be treated. The optimal duration of treatment for patients with disseminated infections is not clear.

Treatment of strongyloidiasis can be difficult and "Strongyloides" has been known to live in individuals for decades; even after treatment. Continued treatment is thus necessary even if symptoms resolve.

Because of the high cost of Stromectol, the veterinary formula Ivomec can be used. Government programs are needed to help citizens finance lifelong medication.

Clothes and sheets must be washed with enzyme washing powder and dried on hot daily.

It is treatable with penicillin or other antibiotics, resulting in a complete recovery.

Some vertically transmitted infections, such as toxoplasmosis and syphilis, can be effectively treated with antibiotics if the mother is diagnosed early in her pregnancy. Many viral vertically transmitted infections have no effective treatment, but some, notably rubella and varicella-zoster, can be prevented by vaccinating the mother prior to pregnancy.

If the mother has active herpes simplex (as may be suggested by a pap test), delivery by Caesarean section can prevent the newborn from contact, and consequent infection, with this virus.

IgG antibody may play crucial role in prevention of intrauterine infections and extensive research is going on for developing IgG-based therapies for treatment and vaccination.

The treatment of TORCH syndrome is mainly supportive and depends on the symptoms present; medication is an option for herpes and cytomegalovirus infections.

Palmar erythema has no specific treatment. Management is based on the underlying cause. When its cause is treated then patients get relief. If it is attributable to a particular drug then the drug should be withdrawn.

TORCH syndrome can be prevented by treating an infected pregnant person, thereby preventing the infection from affecting the fetus.

Each type of vertically transmitted infection has a different prognosis. The stage of the pregnancy at the time of infection also can change the effect on the newborn.

The condition usually resolves on its own, and treatment is not required. Oral antihistamines or topical steroids may be used to decrease itching. Steroids do provide relief from itching, and improve the appearance of the rash, but they also cause the new skin that forms (after the rash subsides) to take longer to match the surrounding skin color. While no scarring has been found to be associated with the rash, scratching should be avoided. It's possible that scratching can make itching worse and an itch-scratch cycle may develop with regular scratching (that is, you itch more because you scratch, so you scratch more because you itch, and so on). Irritants such as soaps with fragrances, hot water, wool, and synthetic fabrics should be avoided. Lotions that help stop or prevent itching may also be helpful.

Direct sunlight makes the lesions resolve more quickly. According to this principle, medical treatment with ultraviolet light has been used to hasten resolution, though studies disagree whether it decreases itching or not. UV therapy is most beneficial in the first week of the eruption.

Oral erythromycin was effective in treating patients in one early trial, but a later study could not confirm these results. Since Human Herpes Virus 6 or Human Herpes Virus 7 has been hypothesized to be the cause, the antiviral drug Acyclovir may reduce length of duration and severity.

Prophylaxis and treatment with an anti-inflammatory agent may stop progression of the reaction. Oral aspirin or ibuprofen every four hours for a day or 60 mg of prednisone orally or intravenously has been used as an adjunctive treatment . However, steroids are generally of no benefit. Patients must be closely monitored for the potential complications (collapse and shock) and may require IV fluids to maintain adequate blood pressure. If available, meptazinol, an opioid analgesic of the mixed agonist/antagonist type, should be administered to reduce the severity of the reaction. Anti TNF-a may also be effective.

The treatment of pulmonary atresia consists of: an IV medication called prostaglandin E1, which is used for treatment of pulmonary atresia, as it stops the ductus arteriosus from closing, allowing mixing of the pulmonary and systemic circulations, but prostaglandin E1 can be dangerous as it can cause apnea. Another example of preliminary treatment is heart catheterization to evaluate the defect or defects of the heart; this procedure is much more invasive. Ultimately, however, the individual will need to have a series of surgeries to improve the blood flow permanently. The first surgery will likely be performed shortly after birth. A shunt can be created between the aorta and the pulmonary artery to help increase blood flow to the lungs. As the child grows, so does the heart and the shunt may need to be revised in order to meet the body's requirements.

The type of surgery recommended depends on the size of the right ventricle and the pulmonary artery, if the right ventricle is small and unable to act as a pump, the surgery performed would be the Fontan procedure. In this three-stage procedure, the right atrium is disconnected from the pulmonary circulation. The systemic venous return goes directly to the lungs, by-passing the heart.Very young children with elevated pulmonary vascular resistance may not able to undergo the Fontan procedure. Cardiac catheterization may be done to determine the resistance before going ahead with the surgery.

Although the organism that causes bejel, "Treponema pallidum endemicum", is morphologically and serologically indistinguishable from "Treponema pallidum pallidum", which causes venereal syphilis, transmission of bejel is not venereal in nature, generally resulting from mouth-to-mouth contact or sharing of domestic utensils, and the courses of the two diseases are somewhat different.

Treatment of aortitis depends on the underlying cause. Infectious causes commonly require antibiotic treatment, while those associated with autoimmune vasculitides are generally treated with steroids.

Management includes the following treatment priorities: stop the inflammation, treat complications, prevent and monitor for re-occurrence.
