Desmopressin (DDAVP) may be used in those with mild haemophilia A. Tranexamic acid or epsilon aminocaproic acid may be given along with clotting factors to prevent breakdown of clots.

Pain medicines, steroids, and physical therapy may be used to reduce pain and swelling in an affected joint.

While there is no cure for haemophilia, treatment improves outcomes.

In regards to the treatment of this genetic disorder, most individuals with severe haemophilia require regular supplementation with intravenous recombinant or plasma concentrate Factor VIII. The preventative treatment regime is highly variable and individually determined. In children, an easily accessible intravenous port ( portacath) may have to be inserted to minimise frequent traumatic intravenous cannulation. These devices have made prophylaxis in haemophilia much easier for families because the problems of "finding a vein" for infusion several times a week are eliminated. However, there are risks involved with their use, the most worrisome being that of infection, studies differ but some show an infection rate that is high These infections can usually be treated with intravenous antibiotics but sometimes the device must be removed, also, there are other studies that show a risk of clots forming at the tip of the catheter.Some individuals with severe haemophilia and most with moderate and mild haemophilia treat only as needed without a regular prophylactic schedule. Mild haemophiliacs often manage their condition with desmopressin, which releases stored factor VIII from blood vessel walls.

Treatment is by intravenous infusion of factor IX, which has a longer half life than factor VIII and as such factor IX can be transfused less frequently. Blood transfusions may be needed, NSAIDS should be discontinued once the individual has been diagnosed with the condition. Any surgical procedure should be done "in concert" with tranexamic acid.

In December 2017, it was reported that doctors had used a new form of gene therapy to treat haemophilia A.

In terms of hemophilia C medication cyklokapron is often used for both treatment after an incident of bleeding and as a preventative measure to avoid excessive bleeding during oral surgery.

Treatment is usually not necessary, except in relation to operations, leading to many of those having the condition not being aware of it. In these cases, fresh frozen plasma or recombinant factor XI may be used, but only if necessary.

The afflicted may often suffer nosebleeds, while females can experience unusual menstrual bleeding which can be avoided by taking birth control such as: IUDs and oral or injected contraceptives to increase coagulation ability by adjusting hormones to levels similar to pregnancy.

Two Dutch studies have followed hemophilia patients for a number of years. Both studies found that viral infections were common in hemophiliacs due to the frequent blood transfusions which put them at risk of getting blood borne infections such as HIV and hepatitis C. In the latest study which followed patients from 1992 to 2001, the male life expectancy was 59 years. If cases with known viral infections were excluded, the life expectancy was 72, close to that of the general population. 26% of the cases died from AIDS and 22% from hepatitis C.

Most people with sickle-cell disease have intensely painful episodes called vaso-occlusive crises. However, the frequency, severity, and duration of these crises vary tremendously. Painful crises are treated symptomatically with pain medications; pain management requires opioid administration at regular intervals until the crisis has settled. For milder crises, a subgroup of patients manage on NSAIDs (such as diclofenac or naproxen). For more severe crises, most patients require inpatient management for intravenous opioids; patient-controlled analgesia (PCA) devices are commonly used in this setting. Diphenhydramine is also an effective agent that doctors frequently prescribe to help control itching associated with the use of opioids.

Management is similar to vaso-occlusive crisis, with the addition of antibiotics (usually a quinolone or macrolide, since cell wall-deficient ["atypical"] bacteria are thought to contribute to the syndrome), oxygen supplementation for hypoxia, and close observation. Should the pulmonary infiltrate worsen or the oxygen requirements increase, simple blood transfusion or exchange transfusion is indicated. The latter involves the exchange of a significant portion of the person's red cell mass for normal red cells, which decreases the percent of haemoglobin S in the patient's blood. The patient with suspected acute chest syndrome should be admitted to the hospital with worsening A-a gradient an indication for ICU admission.

Haemophilia C (also known as plasma thromboplastin antecedent (PTA) deficiency or Rosenthal syndrome) is a mild form of haemophilia affecting both sexes, due to factor XI deficiency. However, it predominantly occurs in Jewish people of Ashkenazi descent. It is the fourth most common coagulation disorder after von Willebrand's disease and haemophilia A and B. In the United States, it is thought to affect 1 in 100,000 of the adult population, making it 10% as common as haemophilia A.

Standard treatment is after delivery. There is tentative evidence about treatment for severe disease before delivery while the baby is inside the womb. As of 2014 the evidence; however, remains insufficient to determine benefits and harms.

Treatment of spina bifida during pregnancy is not without risk. To the mother, this includes scarring of the uterus. To the baby, there is the risk of preterm birth.

Broadly, there are two forms of prenatal treatment. The first is open fetal surgery, where the uterus is opened and the spina bifida repair performed. The second is via fetoscopy. These techniques may be an option to standard therapy.

Most individuals with myelomeningocele will need periodic evaluations by a variety of specialists:

- Physiatrists coordinate the rehabilitation efforts of different therapists and prescribe specific therapies, adaptive equipment, or medications to encourage as high of a functional performance within the community as possible.

- Orthopedists monitor growth and development of bones, muscles, and joints.

- Neurosurgeons perform surgeries at birth and manage complications associated with tethered cord and hydrocephalus.

- Neurologists treat and evaluate nervous system issues, such as seizure disorders.

- Urologists to address kidney, bladder, and bowel dysfunction – many will need to manage their urinary systems with a program of catheterization. Bowel management programs aimed at improving elimination are also designed.

- Ophthalmologists evaluate and treat complications of the eyes.

- Orthotists design and customize various types of assistive technology, including braces, crutches, walkers, and wheelchairs to aid in mobility. As a general rule, the higher the level of the spina bifida defect, the more severe the paralysis, but paralysis does not always occur. Thus, those with low levels may need only short leg braces, whereas those with higher levels do best with a wheelchair, and some may be able to walk unaided.

- Physical therapists, occupational therapists, psychologists, and speech/language pathologists aid in rehabilitative therapies and increase independent living skills.
