Myambutol Tablets-Uses, Side Effects, Overdose, Warnings, Precautions and FAQs


"Myambutol Tablet: A Comprehensive Guide"

Myambutol is a medication primarily prescribed for the treatment of tuberculosis (TB) infections. It contains the active ingredient ethambutol hydrochloride, which works by inhibiting the growth of TB bacteria. This article aims to provide a thorough understanding of Myambutol's uses, potential side effects, overdose risks, precautions, warnings, and answers to frequently asked questions.

Myambutol is an essential component of the standard anti-TB drug regimen. It helps treat active TB infections and prevents the development of drug-resistant strains. It is often prescribed in combination with other TB medications to increase treatment efficacy.

Take this medication by mouth with or without food as directed by your doctor, usually once daily. This medication may sometimes be taken twice weekly. Take this medication exactly as directed by your doctor. The dosage is based on your age, weight, medical condition, and response to treatment.

If you also take antacids that contain aluminum, take this medication at least 4 hours before the antacid.

For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day.

Continue to take this medication (and other TB medications) until the full prescribed amount is finished, even if symptoms disappear. Stopping the medication too early or skipping doses may allow the bacteria to continue to grow, which may result in a return of the infection and cause the infection to be more difficult to treat (resistant).

Side Effects

Common side effects of Myambutol include vision problems, which can range from blurred vision to changes in color perception. These ocular effects are more likely at higher doses or with prolonged use. It's crucial to promptly report any visual changes to your healthcare provider. Other potential side effects include nausea, vomiting, headache, and joint pain.

Patients should be advised to report promptly to their physician any change of visual acuity.

The change in visual acuity may be unilateral or bilateral and hence each eye must be tested separately and both eyes tested together. Testing of visual acuity should be performed before beginning MYAMBUTOL therapy and periodically during drug administration, except that it should be done monthly when a patient is on a dosage of more than 15 mg per kilogram per day. Snellen eye charts are recommended for testing of visual acuity. Studies have shown that there are definite fluctuations of one or two lines of the Snellen chart in the visual acuity of many tuberculouspatients not receiving MYAMBUTOL.

The following table may be useful in interpreting possible changes in visual acuity attributable to MYAMBUTOL.


In case of an overdose, seek immediate medical attention. Overdosing on Myambutol can exacerbate side effects, particularly vision problems. Close monitoring is necessary, and appropriate supportive measures will be taken by healthcare professionals.


- **Vision Monitoring:** Regular eye exams are crucial during Myambutol treatment. If vision changes occur, treatment might need adjustment or discontinuation.

- **Liver/Kidney Function:** Inform your doctor about any pre-existing liver or kidney conditions. Dosage adjustments might be necessary.
