RIFAMPICIN+ISONIAZID
About
ISONIAZID+RIFAMPICIN is used to treat and prevent tuberculosis. Tuberculosis is an infectious disease that mainly affects the lungs, but it can also spread to other body parts such as the kidneys, brain, spine, and bone marrow.
ISONIAZID+RIFAMPICIN is a combination of two anti-tuberculosis drugs Rifampicin, and Isoniazid. Rifampicin inhibits DNA-dependent RNA polymerase activity in the bacteria. Isoniazid inhibits the biosynthesis of mycolic acid, which is the major component of the cell wall. Together, ISONIAZID+RIFAMPICIN kills Mycobacterium tuberculosis, which causes TB (tuberculosis).
In some cases, you may experience certain common side effects, such as drowsiness, dizziness, headache, weakness, muscle pain, heartburn, diarrhoea, gas, and numbness or tingling sensation. 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.
Consult your doctor before taking ISONIAZID+RIFAMPICIN if you are pregnant or planning for pregnancy. Avoid breastfeeding while taking ISONIAZID+RIFAMPICIN as it passes into breast milk. ISONIAZID+RIFAMPICIN may cause dizziness, and vision problems, so drive only if you are alert. Avoid alcohol consumption while taking ISONIAZID+RIFAMPICIN as it could lead to increased drowsiness, dizziness and liver damage.

Patients Concern
Disease/Condition Glossary
Tuberculosis (TB): Tuberculosis is an infectious disease that affects the lungs, but it could also spread to other body parts such as kidneys, brain, spine, and bone marrow. Tuberculosis is caused by a bacteria named Mycobacterium tuberculosis. It is a contagious disease which can spread to others through small droplets released into the air by a person suffering from tuberculosis. Symptoms include a cough that lasts for a few weeks, pain while coughing or with normal breathing, unexplained fatigue, fever, night sweats, loss of appetite and weight. People who smoke or consume alcohol, people diagnosed with HIV, and immune system problems are more likely at risk of developing active TB.
