Flagyl, metronidazole information
 
Other names: Helidac Therapy
 
What is Flagyl (Metronidazole, Helidac Therapy)?
Flagyl is an antibacterial drug. It is used to kill any bacteria in the body that are causing infection.
 
How is Flagyl taken?
Flagyl is taken orally in tablet form. It is important to maintain a constant level of Flagyl in the blood. Therefore, it must be taken at regular intervals without missing any doses. Take Flagyl with 8 ounces of water (one glass). Flagyl can be taken by itself, or with meals. If dry mouth occurs, chewing gum, hard candy or ice chips may help.
 
Why is Flagyl prescribed?
Flagyl (Metronidazole, Helidac Therapy) is used to fight or prevent a bacterial infection. It is used for a wide variety of infections including those in the abdomen, bones, joints, nervous system, respiratory tract, skin as well as vaginal and intestinal infections.

What do I do if I miss a dose?
If you miss a dose, take it as soon as you remember. If your next dose should be taken soon, just take that dose. Do not double up, or take more than one dose at a time. 
 
Who should not take Flagyl (Metronidazole, Helidac Therapy)?
Pregnant women in their first trimester should not take Flagyl for vaginal infections. People with an allergy or sensitivity to metronidazole should also not take Flagyl.
 
Flagyl should be used under the close supervision of a physician by anyone with liver disease.
Yeast infections may worsen while taking Flagyl.
 
If I start to feel better, can I stop taking Flagyl?
No, as you are treated with Flagyl (Metronidazole, Helidac Therapy) you may start to feel better, but that does not mean the infection is entirely gone. Take all of the medication that was prescribed to you unless instructed to stop taking it by a health care professional. Stopping the medication before the bacterial infection is completely gone can result in serious consequences. A stronger strain of bacteria may develop, or the infection may come back again and be more difficult to treat.
 
 
What are the side effects?
The most serious side effects from Flagyl are seizures and tingling or numbness in the extremities (arms, legs, hands and feet). If you experience these symptoms stop taking Flagyl and call your doctor immediately.
Other side effects include abdominal cramping, diarrhea, headache, nausea, loss of appetite and vomiting.

Take care to avoid alcohol from unexpected sources, such as over the counter cough suppressants or cold products (Nyquil, for example).
 
Is Flagyl (Metronidazole, Helidac Therapy) safe during pregnancy?

Notify the prescribing doctor if you become pregnant while taking Flagyl. Flagyl does pass into breast milk, and could affect a nursing infant. It should be used in nursing mothers with care.
