Rf-4 Kit Tab belongs to the group of medicines called anti-tuberculosis drugs primarily used to treat tuberculosis. Tuberculosis is an infectious disease that mainly affects the lungs, but it can also spread to other body parts such as kidneys, brain, spine and bone marrow. Rf-4 Kit Tab does not work against infections caused by the virus, including cold and flu.

Rf-4 Kit Tab is a combination of four anti-tuberculosis drugs, namely: Rifampicin, isoniazid, pyrazinamide and ethambutol. Isoniazid prevents the formation of the bacterial cell wall, while rifampicin inactivates a bacterial enzyme (RNA-polymerase) which is required by TB bacteria (Mycobacterium tuberculosis) to make essential proteins and to reproduce. Ethambutol and pyrazinamide work by slowing the growth of bacteria. Altogether, they kill the bacteria and treat the infection.

The dose and duration of Rf-4 Kit Tab can vary depending upon your condition and severity of the infection. In some cases, you may experience certain common side-effects such as weakness, nausea, vomiting, malaise (feeling of discomfort), fatigue and vision problems. Most of these side-effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side-effects persistently.

Avoid foods and drinks containing histamine or tyramine such as cured meat, matured cheese, soya, tuna, salmon, mackerel, wine and beer while taking Rf-4 Kit Tab as they might cause interaction. Maintain a gap of one hour between Rf-4 Kit Tab and antacid medicines. Consult your doctor before taking Rf-4 Kit Tab if you are pregnant. Avoid breastfeeding while taking Rf-4 Kit Tab as it passes into breast milk. Rf-4 Kit Tab is not recommended for use in children. Rf-4 Kit Tab may cause dizziness and vision problems, so drive only if you are alert. Avoid consuming alcohol along with Rf-4 Kit Tab as it might lead to liver problems and increased dizziness.
