About RF-HE Tablet Kit

RF-HE Tablet Kit 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.

RF-HE Tablet Kit 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, which is necessary for growth. This ultimately prevents or kills the bacteria and prevents its spread.

RF-HE Tablet Kit 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 RF-HE Tablet Kit only after consulting with a doctor. Pregnant women and breastfeeding mothers should take RF-HE Tablet Kit as instructed by the doctor. Do not take this medicine with alcohol, which causes drowsiness. While on the medication, your doctor advises some diagnostic and laboratory tests to know the effects of drugs on the body. Use of RF-HE Tablet Kit may also affect oral contraceptive pills, so if you are using any, please consult a doctor and ask for some other birth control methods. You may experience dark-coloured urine and yellowing of teeth after using RF-HE Tablet Kit. However, these are harmless symptoms and may go after stopping RF-HE Tablet Kit.

Medicinal Benefits

RF-HE Tablet Kit is an antibiotic active against the mycobacterium strain of bacteria, which causes TB infection. Rifampicin, Ethambutol, and Isoniazid prevent the bacteria's growth by interfering with the cell wall and DNA (the genetic material of bacteria) required to survive the bacteria. RF-HE Tablet Kit is active against Mycobacterium bacteria which causes TB and leprosy.
