About Rifampicin+isoniazid+pyridoxine
Isoniazid+pyridoxine+rifampicin belongs to the group of medicines called anti-tuberculosis drugs primarily 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+pyridoxine+rifampicin is also used in the treatment of leprosy (infectious disease-causing skin lesions and nerve damage), legionnaires disease (a type of pneumonia caused by legionella bacteria), brucellosis (bacterial infection), and serious staphylococcal infections.
Isoniazid+pyridoxine+rifampicin is a combination of three drugs, namely: Rifampicin, Pyridoxine (vitamin B6), and Isoniazid. Rifampicin works by inactivating a bacterial RNA-polymerase, an enzyme that allows TB bacteria to make and replicate essential proteins. Isoniazid prevents the creation of its protective coating by these bacteria. Together, they destroy the bacteria named Mycobacterium tuberculosis, which causes TB (tuberculosis), and the infection is eliminated. Vitamin B6 treats nerve damage (neuritis) caused by tuberculosis (TB), treating drugs like isoniazid.
Take Isoniazid+pyridoxine+rifampicin as prescribed. The dose and duration of Isoniazid+pyridoxine+rifampicin can vary depending on your condition and the severity of the infection. In some cases, you may experience certain common side effects such as severe diarrhea, possibly with blood in the stools, hypertension, kidney problems, severe stomach pain, mental disturbances, constipation, dry mouth, and upset stomach. 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.
Do not stop taking Isoniazid+pyridoxine+rifampicin despite symptomatic relief. Treat your condition effectually. Continue taking Isoniazid+pyridoxine+rifampicin for as long as it has been prescribed for you. Avoid foods and drinks containing histamine or tyramine such as cured meat, matured cheese, soya, tuna, salmon, mackerel, wine, and beer while taking Isoniazid+pyridoxine+rifampicin as they might cause interaction. Maintain a gap of one hour between Isoniazid+pyridoxine+rifampicin and antacid medicines. Consult your doctor before taking Isoniazid+pyridoxine+rifampicin if you are pregnant or planning for pregnancy. Avoid breastfeeding while taking Isoniazid+pyridoxine+rifampicin as it passes into breast milk. Isoniazid+pyridoxine+rifampicin may cause dizziness, and vision problems, so drive with caution. Avoid alcohol consumption while taking Isoniazid+pyridoxine+rifampicin as it could lead to increased drowsiness, dizziness, and liver damage. Isoniazid+pyridoxine+rifampicin may make the 'contraceptive pill” less effective. So, use a reliable barrier method of contraception such as condoms while on Isoniazid+pyridoxine+rifampicin.

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 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 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.
