Mycobutol 400 mg Tablet

Mycobutol 400 mg Tablet is a prescription antibiotic tablet that contains 400 mg of ethambutol in each tablet. Ethambutol is used as part of combination treatment for tuberculosis (TB), not by itself. The Mycobutol 400 mg Tablet is taken with other anti-TB medicines to help treat active TB infection and to reduce the chance of resistance.

How it works: Ethambutol in Mycobutol 400 mg Tablet works by blocking a step bacteria need to build their protective cell wall. Without that wall, the TB germs cannot grow and spread as well, especially when the tablet is used with other TB medicines.

Mycobutol 400 mg Tablet is a higher-strength option compared with Mycobutol 100 mg, which can help a doctor build the exact total daily dose using fewer tablets. This strength may suit adults or older children who need a dose that matches their weight and treatment plan, and it can make dosing simpler than using several lower-strength tablets. A clinician chooses the tablet strength based on the full TB regimen, body weight, and kidney function.

• Have regular eye checks while using ethambutol, because vision changes can happen during treatment.

Each Mycobutol 400 mg Tablet provides 400 mg of ethambutol. The number of tablets and how often you take them depends on your weight, kidney function, and the other TB medicines in your regimen; for many patients it is taken once daily, but the prescriber may use a different schedule. Do not assume a maximum daily dose on your own, because the doctor determines the safest total dose for this specific strength.

Do not change your dose or stop the medicine without speaking to your doctor.
