Introduction
Rifampicin with Isoniazid and Pyrazinamide (RIF) is a combination of medicines used to treat various types of bacterial infections. This combination of drugs is often used to treat tuberculosis (TB). It is also used to prevent people with latent TB from developing active TB.
Uses
RIF is used to treat primary and secondary cases of tuberculosis. It can also be used in children and people with HIV infections.
Mechanism of Action
RIF works by inhibiting the synthesis of bacterial cell-wall components, which leads to a decrease in cell division and death of the bacteria. In addition, Isoniazid and Pyrazinamide act as bactericidal inhibitors which prevent the release of Mycobacterium tuberculosis from the infected cells.
How Long Does It Take to Work?
The effectiveness of RIF treatment is dependent on the duration and dose of the medication. It usually takes around two to three months for the treatment to be effective.
Absorption
Rifampicin is poorly absorbed when taken orally, so it is usually given as an injectable form. Isoniazid and Pyrazinamide are both rapidly and completely absorbed when taken orally.
Route of Elimination
Rifampicin is excreted in urine, feces and bile. Isoniazid and Pyrazinamide are mainly eliminated in the urine.
Dosage
RIF is usually given as an injectable or oral form. The usual dose of RIF is 600mg to 1200mg of Rifampicin, 300mg to 600mg of Isoniazid, and 800mg to 1600mg of Pyrazinamide. The dose and duration of therapy depend on the severity of the infection.
Administration
RIF is usually taken orally or as an injectable form. It should be taken three times per week at least two hours before breakfast or four hours after meals. It should be taken with a full glass of water.
Side Effects
Common side effects of RIF include nausea, vomiting, headache, rash, and diarrhea. More serious side effects may include liver damage, low blood pressure, and kidney failure.

Precaution
Before taking RIF, it is important to inform the doctor of any existing medical condition, past diagnoses, and current medications. In addition, women who are pregnant or breastfeeding should consult their doctor before taking this medication.
