R-Cinex Capsule (Isoniazid + Rifampicin) | Antitubercular Medicine for Tuberculosis (TB) Treatment

Precaution

R-Cinex Capsule should be used under medical supervision. Isoniazid and rifampicin can affect the liver, so people with liver disease or a history of liver problems should inform their healthcare professional before treatment.

Contact a healthcare professional if symptoms such as persistent nausea, loss of appetite, unusual tiredness, abdominal discomfort, dark urine, or yellowing of the skin or eyes occur, as these may indicate liver problems.

Isoniazid may also cause peripheral neuropathy, particularly in people with certain risk factors. A healthcare professional may recommend vitamin B6 (pyridoxine) supplementation for some patients.

Inform the healthcare professional about all prescription medicines, over-the-counter medicines, vitamins, and supplements being taken because rifampicin can interact with many medicines.

Alcohol should generally be avoided during treatment because of the potential for increased liver toxicity.

Usage

Take R-Cinex Capsule exactly as prescribed by the healthcare professional. It is generally taken on an empty stomach, approximately one hour before or two hours after food, unless otherwise instructed.

Swallow the capsule whole with water. Take it at the prescribed time each day and follow the complete treatment schedule.

Do not stop tuberculosis treatment early or change the dose without medical advice, even if symptoms improve. Missing doses or stopping treatment without guidance can affect treatment response and may contribute to drug resistance.

Uses

R-Cinex Capsule is used as part of treatment for tuberculosis (TB) caused by susceptible Mycobacterium tuberculosis.

It may be included in treatment regimens for tuberculosis involving:

• Pulmonary tuberculosis
• Certain forms of extrapulmonary tuberculosis
• Tuberculosis affecting other organs, when included in the prescribed treatment regimen

The exact combination of medicines and duration of therapy depend on the type of TB, susceptibility results, previous treatment history, and individual patient factors. Active TB should be treated with an appropriate combination of anti-tuberculosis medicines.

Side Effects

Possible side effects of R-Cinex Capsule may include:

Rifampicin may also cause orange-red discoloration of urine, sweat, saliva, or tears. This can occur during treatment and should be discussed with a healthcare professional if there is uncertainty about the symptom.

Seek prompt medical attention for severe weakness, persistent vomiting, yellow skin or eyes, dark urine, severe rash, breathing difficulty, unusual bleeding, significant vision changes, or severe numbness or weakness.

Interactions

R-Cinex Capsule can interact with several medicines because rifampicin can change the activity of drug-metabolizing enzymes and transport systems.

Important interactions may include:

• Oral hormonal contraceptives: Rifampicin can reduce their effectiveness.
• Warfarin and other anticoagulants: Blood-thinning effects may be altered.
• Phenytoin and carbamazepine: Blood levels may be affected.
• Certain HIV medicines: Rifampicin can interact with several antiretroviral medicines.
• Other medicines affecting the liver: Combined use may increase the risk of liver-related problems.
