Rifampicin Capsules
Product Overview
Rifampicin is a broad-spectrum antibiotic belonging to the rifamycin class, primarily used to treat various bacterial infections, notably tuberculosis and leprosy. It functions by inhibiting bacterial RNA synthesis, effectively eliminating susceptible bacteria.
Indications
-
Tuberculosis (TB): Rifampicin is a cornerstone in the treatment of active tuberculosis infections, typically used in combination with other antitubercular agents to prevent resistance development.
-
Leprosy: Employed as part of multi-drug therapy to treat Hansen's disease.
-
Prophylaxis for Neisseria meningitidis: Used to eliminate meningococcal bacteria from the nasopharynx in asymptomatic carriers, reducing the risk of meningitis outbreaks.
Dosage and Administration
-
Adults: The standard dose for tuberculosis is 10 mg/kg, up to a maximum of 600 mg daily, administered orally on an empty stomach, either 1 hour before or 2 hours after meals, to enhance absorption.
-
Children: Dosage is weight-based; typically, 10–20 mg/kg daily, not exceeding 600 mg per day.
-
Administration: Capsules should be swallowed whole with a full glass of water. Consistent daily dosing is crucial for treatment efficacy.
Precautions
-
Liver Function: Rifampicin can cause hepatotoxicity; therefore, liver function tests should be conducted before and during treatment, especially in patients with pre-existing liver conditions.
-
Drug Interactions: Rifampicin is a potent inducer of hepatic enzymes, which can reduce the effectiveness of other medications, including oral contraceptives, anticoagulants, and antiretrovirals.
-
Discoloration of Body Fluids: Patients should be informed that rifampicin may cause a red-orange discoloration of urine, sweat, saliva, and tears, which is harmless but can stain clothing and contact lenses.

-
Gastrointestinal Disturbances: Nausea, vomiting, diarrhea, or abdominal pain.
-
Allergic Reactions: Rash, itching, or more severe hypersensitivity reactions.
-
Flu-like Symptoms: Fever, chills, and muscle aches, particularly with intermittent dosing.
-
Hepatotoxicity: Elevated liver enzymes, jaundice; monitoring is essential.
Storage
