What is Cycloserine and how is it used?
Cycloserine is an antibiotic medication used in combination with other drugs to treat tuberculosis and urinary tract infections. It works by inhibiting bacterial growth and is effective only against bacterial infections, not viral ones like the common cold. Available as an oral capsule, it is typically taken twice daily, with or without food, as prescribed. Consistent dosing at evenly spaced intervals is important for effectiveness. It is crucial to complete the entire prescribed course, even if symptoms improve, to prevent the infection from recurring.
What side effects are associated with Cycloserine?
Common side effects may include headache, drowsiness, dizziness, or tremors; consult your doctor if these are persistent or bothersome. While serious side effects are less common, they can occur. Seek immediate medical attention for signs of a severe allergic reaction, such as rash, itching, swelling of the face or throat, severe dizziness, or difficulty breathing. Your healthcare provider has determined that the potential benefits of this treatment outweigh the risks for your condition. This list is not exhaustive, so discuss all possible side effects with your doctor or pharmacist.
