Ethambutol/isoniazid/rifampicin

Ethambutol/Isoniazid/Rifampicin is a combination medication used in the treatment of tuberculosis. It contains three antibiotics: ethambutol, isoniazid, and rifampicin. This combination is often used in the initial phase of tuberculosis treatment to reduce the development of drug resistance.

Composition

The medication is composed of three active ingredients:

• Ethambutol: This antibiotic interferes with the formation of the cell wall in the Mycobacterium tuberculosis bacteria, causing them to die.
• Isoniazid: Isoniazid is a first-line antitubercular medication that works by preventing the bacteria from forming mycolic acid, which is necessary for their cell walls.
• Rifampicin: Rifampicin inhibits DNA-dependent RNA polymerase in the bacteria, preventing them from replicating.

Usage

Ethambutol/Isoniazid/Rifampicin is used in the initial phase of tuberculosis treatment, typically for two months. This is followed by a continuation phase of four to six months with isoniazid and rifampicin alone. The medication is taken orally, usually once a day.

Side Effects

Like all medications, Ethambutol/Isoniazid/Rifampicin can cause side effects. These may include:

• Hepatitis
• Peripheral neuropathy
• Optic neuritis
• Rash
• Nausea
• Vomiting

Patients should contact their healthcare provider if they experience any unusual symptoms while taking this medication.

Precautions

Before starting treatment with Ethambutol/Isoniazid/Rifampicin, patients should inform their healthcare provider if they have any other medical conditions, especially:

• Liver disease
