Cycloserine Capsules USP 250 mg
Cycloserine is an antibiotic used to treat tuberculosis when first-line medicines are not enough. It is taken by mouth and is available without a prescription in Nigeria, but medical supervision is strongly advised because of serious side effects.
What it is
Cycloserine is an antibiotic used to treat tuberculosis (a bacterial infection that usually affects the lungs). It is known as a second-line medicine, meaning it is used when standard tuberculosis drugs have not worked well.
What it's used for
Cycloserine is used for active tuberculosis of the lungs and other parts of the body (such as the kidneys) when the bacteria are sensitive to it. It must always be taken together with other tuberculosis medicines, never alone. It may also be used for some urinary tract infections caused by bacteria that are susceptible to it.
Common side effects
Common side effects affect the nervous system and may include: drowsiness, headache, tremor, slurred speech, dizziness, confusion, memory loss, and mood changes such as depression or psychosis (including suicidal thoughts). Seizures (convulsions) can also occur, especially with higher doses. Other reactions include skin rash and allergic reactions.
Important cautions
Do not take cycloserine if you have a history of epilepsy, severe depression, anxiety, psychosis, or if you have severe kidney disease. Also avoid it if you are allergic to cycloserine or if you drink excessive amounts of alcohol. If you develop any nervous system symptoms (such as confusion, drowsiness, headache, or seizures), stop the medicine and contact your doctor immediately – the dose may need to be lowered or treatment stopped. Blood levels above 30 mcg/mL increase the risk of toxicity, so blood tests are typically done.
