Flagyl Information:

What is Flagyl?

Flagyl is an antibacterial medicine and is prescribed for treating certain types of bacteria and protozoa-induced illnesses and infections in the gastrointestinal system and reproductive system. Other Flagyl uses include treating gynecologic infections as well as infections of the skin, bones and joints, central nervous system, respiratory system, and other parts of the body. It is not used to treat viral infections.

How do I take Flagyl?

Flagyl is available in either capsule or tablet form and is taken orally two or three times a day with liquid for one to two weeks or longer. It can be taken with or without food. Treatment with Flagyl medicine is individualized, so the dosage strength and frequency varies among patients. Flagyl uses center only on those illnesses caused by bacteria believed susceptible to treatment with this medication.

Before taking Flagyl, tell your doctor if:

  • You are allergic to metronidazole or any ingredients in a Flagyl tablet or capsule
  • You are allergic to any types of medication
  • You are taking blood thinners or anticoagulants such as Warfarin

If any of these problems persist or worsen, contact your healthcare professional.

Severe Flagyl side effects requiring immediate medical attention include pain in the joints, symptoms of an allergic reaction (rash, hives, itching, and swelling of the mouth, lips, tongue, or throat), fever, and a stuffy nose.

What if I forget to take a dose of Flagyl?

If you forget to take Flagyl at the prescribed time, take it as soon as you remember and are able. However, if it is near to the time for the next scheduled dose, forego the missed one and resume the normal schedule. Do not take multiple doses of this medication.

How do I store Flagyl?

Keep Flagyl medicine tightly sealed in its original container, out of the reach of children and away from extremes of temperature and humidity. Dispose of any unused or expired capsules or tablets according to the instructions of your pharmacist.

What happens if I overdose on Flagyl?

When there is an overdose of Flagyl, contact the Poison Control Center at 1-800-222-1222. If the individual has stopped breathing or lost consciousness, call Emergency Services at 911.
