Filmet 400mg Tablet 1 Strip

Introduction
Filmet 400 is an antibiotic medicine that helps your body fight infections caused by bacteria and parasites. It is used to treat infections of the liver, stomach, intestines, vagina, brain, heart, lungs, bones and skin. Filmet 400 helps prevent an infection after surgery. It is also used in the treatment of dental infections, leg ulcers and pressure sores. This medicine is best taken after eating some food. It should be taken at the same time each day to get the most benefit. The amount you are advised will depend on what you are being treated for and how bad it is, but you should take this antibiotic exactly as prescribed by your doctor. Your symptoms may get better after a short time but do not stop taking it until you have finished a full course of treatment, even if you feel well. If you stop taking it early, some bacteria may survive, and the infection may come back. Do not drink any alcohol while taking this medicine and for a few days after stopping it. Otherwise, you may get unpleasant side effects like nausea, vomiting and stomach pain. The most common side effects of this medicine are headache, dryness in mouth, nausea, and a slight metallic taste in the mouth. These are usually mild but let your doctor know if they bother you or last more than a few days. You can try using sugarless candies or lozenges to overcome any dryness or metallic taste in the mouth. Before using this medicine, inform your doctor if you are allergic to any medicine or have any kidney or liver problems or any disease of the nervous system. Your doctor may change the dose or prescribe a different medicine. If you are pregnant or breastfeeding, inform your doctor before taking this medicine.

Mode of Action
Metronidazole is converted to reduction products that interact w/ DNA to cause destruction of helical DNA structure and strand leading to a protein synthesis inhibition and cell death in susceptible organisms. It is active against most anaerobic protozoa, some gm+ve, gm-ve and facultative anaerobes.
Precaution
Patients with CNS diseases; discontinue IV therapy if abnormal neurologic symptoms occur. History of seizure disorder. Evidence or a history of blood dyscrasias; perform total and differential leukocyte counts before and after treatment. Severe hepatic impairment; monitor plasma levels.

Interaction
Concurrent use w/ disulfiram may produce psychotic reactions. May potentiate the effect of oral anticoagulants. May increase risk of lithium toxicity. May reduce the renal clearance resulting to increased toxicity of 5-fluorouracil. May increase serum levels of ciclosporin.
