It is also a drug approved by the Food and Drug Administration to treat primary and certain secondary carnitine-deficiency syndromes secondary to inherited diseases. Drug interactions and adverse effects
Carnitine interacts with pivalate-conjugated antibiotics such as pivampicillin. Chronic administration of these antibiotics increases the excretion of pivaloyl-carnitine, which can lead to carnitine depletion. Treatment with the anticonvulsants valproic acid, phenobarbital, phenytoin, or carbamazepine significantly reduces blood levels of carnitine.When taken in the amount of roughly 3 grams (0.11 oz) per day, carnitine may cause nausea, vomiting, abdominal cramps, diarrhea, and body odor smelling like fish. Other possible adverse effects include skin rash, muscle weakness, or seizures in people with epilepsy. History
Levocarnitine was approved by the U.S. Food and Drug Administration as a new molecular entity under the brand name Carnitor on December 27, 1985. See also

Unfortunately, having chronic erythrocyte transfusions, it can be extremely harmful to the body and can cause severe complications.To help with dry eye symptoms and visual function, topical lubrication can be used. A more invasive way to help treat Gunthers disease would be to have surgery. There have been numerous studies that have stated that bone marrow transplantation is successful. This is a recently new development for Gunthers disease so the long-term effects are still unresourced. If a patient has a life-threatening infectious complication then bone marrow transplantation is no longer relevant for them. There are also reports that stem cell transplantation is successful in a limited number of participants
