Rifampicin+ethambutol+isoniazid
About Rifampicin+ethambutol+isoniazid
Rifampicin+ethambutol+isoniazid belongs to the group of antibiotics called 'antituberculosis agents' used to treat tuberculosis (TB) caused by the bacteria mycobacterium tuberculin. Infectious or harmful bacteria can make you sick and reproduce quickly in your body. These harmful bacteria produce toxins which can damage tissue and make you sick. Tuberculosis (TB) usually attacks your lungs and can also spread to the brain and spine. Common signs and symptoms of TB include fever, cough (sometimes blood-tinged), weight loss, and night sweats.
Rifampicin+ethambutol+isoniazid contains Rifampicin, Ethambutol, and Isoniazid. Rifampicin inhibits DNA synthesis (a process required for bacterial growth and division). On the other hand, Ethambutol and Isoniazid prevent bacterial cell wall (outer covering) synthesis necessary for its growth. This ultimately prevents or kills the bacteria and prevents its spread.
Rifampicin+ethambutol+isoniazid should be taken as directed by the doctor. You may experience common side effects like nausea, vomiting, fever, dark-coloured urine, sweating, and increased saliva. Everyone need not undergo the above symptoms. If any discomfort occurs from this medicine, consult your doctor.
People with liver and kidney diseases should take Rifampicin+ethambutol+isoniazid only after consulting with a doctor. Pregnant women and breastfeeding mothers should take Rifampicin+ethambutol+isoniazid as instructed by the doctor. Do not take this medicine with alcohol which causes drowsiness.

You may experience dark-coloured urine and yellowing of teeth after using Rifampicin+ethambutol+isoniazid.
