Rifampicin
About Rifampicin
Rifampicin is used in combination with other medicines to treat tuberculosis (TB). Tuberculosis is an infectious respiratory disease that affects the lungs but can also spread to other body parts such as the kidneys, brain, spine, and bone marrow. It is also used to treat other bacterial infections. Rifampicin does not work against infections caused by the virus, including cold and flu. As Rifampicin is an antibiotic, it does not work against infections caused by the virus, including cold and flu. The bacteria causing tuberculosis (TB) are highly contagious and spread from one person to another via tiny droplets released into the air (through coughs or sneezes).
Rifampicin consists of a drug called 'rifampicin', which works by inactivating a bacterial protein enzyme (RNA-polymerase) and inhibits bacterial cell death. Rifampicin acts against the bacteria called Mycobacterium tuberculosis, which causes TB (tuberculosis).
Rifampicin should be taken as recommended by your doctor. It should be taken 30 minutes before food or 2 hours after food on an empty stomach. In some cases, you may experience certain common side effects, such as drowsiness, dizziness, headache, weakness, muscle pain, heartburn, diarrhea, gas, and numbness or tingling sensation. Most of these side effects are mild and subside over time. However, if any of these effects persist, contact your doctor immediately.
Rifampicin may raise liver enzymes like ALT and can cause jaundice if taken longer. Hence, a regular liver function test (LFT) is recommended while taking treatment with Rifampicin. Maintain a gap of one hour between Rifampicin and antacid medicines. Rifampicin is not recommended if you are pregnant or planning for pregnancy. Avoid breastfeeding while taking Rifampicin as it passes into breast milk. Rifampicin may cause dizziness, and vision problems; hence avoid driving vehicles or operating machines that require mental concentration. Avoid alcohol consumption while taking Rifampicin as it could lead to increased drowsiness, dizziness, and liver damage.
Uses of Rifampicin
Medicinal Benefits
Rifampicin contains 'Rifampicin' that treats Tuberculosis (TB) by inactivating a bacterial genetic material that allows TB bacteria to make a copy of its protein for further growth inside the host cell (human). Rifampicin is active against gram-positive cocci bacteria like Mycobacteria and Clostridium difficle and gram-negative bacteria like Neisseria meningitides, N. gonorrhoeae and Hemophilus influenzae. Rifampicin is also used as a second-line treatment in the treatment of cholestatic pruritus. It also treats leprosy and severe gram-positive bacterial infections (like osteomyelitis, endocarditis, brain abscess, meningitis and implant infections) in combination with other antibiotics.

Safety Advice
Alcohol
cautionRifampicin intake is not recommended with alcohol. A patient is not advised to take alcohol with Rifampicin as it may increase chances of liver damage.
Pregnancy
unsafeNot recommended during pregnancy. Tell your doctor if you are pregnant or planning to become pregnant. Rifampicin should not be taken during pregnancy as it can affect your unborn baby's growth and may cause complications to the mother and baby after birth.
Breast Feeding

Liver
cautionNot recommended to be taken in liver patients without doctors consultation as Rifampicin has been found to affect liver function with raised ALT enzymes.
Kidney
cautionNot recommended for kidney patients without doctor's consultation. Intake of Rifampicin in these people may result in symptoms like blood in the urine, a change in the amount of urine passed and feeling drowsy or weak.
Children
safe if prescribedRifampicin is safe to be prescribed in children below 12 years. Dose adjustments by the doctor are done according to age, weight, and severity of infection

Rifampicin may affect test results of some blood tests such as folate, vitamin B12, and liver function tests. Hence inform your doctor or the lab person if any such tests are advised.
Patients Concern
Disease/Condition Glossary
Tuberculosis (TB): It is an infectious disease that affects the lungs, but it could also spread to other body parts such as the kidneys, brain, spine, and bone marrow. Tuberculosis is caused by a bacteria named Mycobacterium tuberculosis. It is a contagious disease that 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 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.
