Overview of Myambutol

Myambutol is an antibiotic primarily prescribed for the treatment of tuberculosis. It specifically targets the actively dividing cells of Mycobacterium tuberculosis by inhibiting bacterial RNA synthesis, disrupting metabolism, and preventing bacterial replication, leading to bacterial death. This medication is effective even against strains of mycobacteria resistant to drugs like streptomycin, isoniazid, ethionamide, and kanamycin.

Dosage and Administration

Always follow your healthcare provider's instructions when taking Myambutol. Do not start or discontinue the medication without consulting your doctor. To reduce the risk of stomach upset, take the medication with food or milk. Patients with impaired kidney function may require dose adjustments.

Important Precautions

Using Myambutol alone without other anti-tuberculosis medications can lead to the rapid development of resistant bacterial strains, so it is typically combined with other treatments.

Contraindications

• Allergy to Myambutol
• Patients with optic neuritis, cataracts, diabetic retinopathy, or other inflammatory eye conditions
• Individuals suffering from gout
• Children under 13 years old
• Pregnant or breastfeeding women
• Patients with chronic kidney failure

Possible Side Effects

Common side effects include stomach discomfort, dizziness, fatigue, and headaches, which often lessen as the body adjusts. Notify your doctor if symptoms worsen. Allergic reactions such as rash, swelling, or tingling sensations in the hands or feet require prompt medical attention. Vision changes, difficulty distinguishing green and red colors, sudden loss of color vision, or blurred eyesight are urgent symptoms that need immediate evaluation. Persistent or severe nausea, vomiting, abdominal pain, dark urine, or jaundice could indicate serious liver issues and must be reported to your doctor immediately.

Drug Interactions

Myambutol can enhance the effects of other anti-tuberculosis drugs and increase neurotoxicity risks when combined with medications such as ciprofloxacin, carbamazepine, asparaginase, aminoglycosides, lithium salts, imipenem, methotrexate, and quinine.

Missed Dose Instructions

If you forget to take a dose, take it as soon as you remember unless the next dose is near. In that case, skip the missed dose and resume your regular schedule. Do not double the dose to compensate.

Overdose Information

The symptoms of an overdose are not well documented. If you suspect an overdose, seek emergency medical care immediately.

Storage Guidelines

Store Myambutol in a cool, dry place at room temperature, inside a tightly closed container, away from moisture.
