General Information

Flagyl is effective against a variety of fungi and some bacteria. It may be prescribed for symptomless diseases when the doctor feels that an underlying infection may be involved. For example, asymptomatic women may be treated with this drug when vaginal examination shows evidence of Trichomonas. Because vaginal Trichomonas infection is a venereal disease, asymptomatic sexual partners of treated patients should be treated at the same time if the organism has been found in the woman’s genital tract This is needed to prevent reinfection of the partner. The decision to treat an asymptomatic male partner without evidence of infection must be made by the doctor. Metronidazole kills microorganisms by disrupting the DNA of the organism after it enters the cell.

Special Information about Flagyl Generic

1. Call your doctor if you become dizzy or light-headed while taking this drug, or if you develop numbness, tingling, pain, or weakness in your hands or feet, or seizures (with high doses of Flagyl generic). Rare side effects that demand your doctor’s attention include clumsiness or unsteadiness; mood changes; unusual vaginal irritation, discharge, or dryness; skin rash, hives, or itching; or severe pain of the back or abdomen accompanied by vomiting, appetite loss, or nausea. Call your doctor if other side effects become particularly bothersome or persistent.
2. Metronidazole may cause darkening of your urine; this is probably not important, but inform your doctor if this happens.
3. Follow your doctor’s dosage instructions faithfully and don’t stop until the full course of therapy has been taken.
4. Metronidazole may cause dry mouth, which usually can be relieved with ice, hard candy, or gum. Call your doctor or dentist if dry mouth persists for more than 2 weeks.
5. If you forget to take a dose of Metronidazole, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take a double dose.

Cautions and Warnings

You should not use this drug if you have a history of blood disease or if you know that you are sensitive or allergic to Flagyl.

People taking this medication have experienced seizures, numbness, or tingling in the hands or feet. This effect is rare with low doses but may be more common in people taking larger doses for long periods (i.e., in Crohn’s disease).

If this happens to you, stop taking the medicine and call your doctor at once. Metronidazole should be taken with caution if you have active nervous-system disease (including epilepsy) or if you have severe liver problems.

Possible Side Effects

• Most common: gastrointestinal (GI) tract symptoms, including nausea (sometimes accompanied by headache), dizziness, loss of appetite, occasional vomiting, diarrhea, stomach upset, abdominal cramping, and constipation. A sharp, unpleasant metallic taste is also associated with the use of this drug.
• Less common: numbness or tingling in the extremities and occasional joint pains, confusion, irritability, depression, difficulty sleeping, and weakness. Itching and a sense of pelvic pressure also have been reported.
• Rare: clumsiness or poor coordination, fever, increased urination, seizures, incontinence, and reduced sex drive.

Drug Interactions

• Avoid alcoholic beverages.: Interaction with Flagyl may cause abdominal cramps, nausea, vomiting, headaches, and flushing. Modification of the taste of alcoholic beverages has also been reported. Metronidazole should not be used if you are taking Disulfiram (used to maintain abstinence from alcohol), because the combination can cause confusion and psychotic reactions.
• People taking oral anticoagulant (blood-thinning) drugs such as Warfarin will have to have their dose reduced because Metronidazole increases the effect of anticoagulants.
• Flagyl raises Lithium blood levels, effects, and toxicity.
• Cimetidine can interfere with the liver’s ability to break down Metronidazole, causing increased amounts of Metronidazole in your blood. Your Metronidazole dosage may have to be reduced if you are taking Cimetidine.
• Phenobarbital and other barbiturates Can increase the rate at which Metronidazole is broken down, compromising its effectiveness.
• Drugs that cause nervous-system toxicity – such as Mexiletine, Ethambutol, Isoniazid, Lindane, Lincomycin, Lithium, Pemoline, Quinacrine, and long-term high-dose vitamin B6 (Pyridoxine) – should not be taken with Metronidazole because nervous-system effects may be increased.
• Metronidazole may increase blood levels of Phenytoin by interfering with its breakdown in the liver. This could increase the risk of Phenytoin side effects and might result in the need to adjust your Phenytoin dosage.

Food Interactions

This drug is best taken with food to avoid stomach upset.

Special Populations

Pregnancy/Breast-feeding

Metronidazole passes into the fetal blood circulation soon after it is taken. This drug should not be taken during the first 3 months of pregnancy and should be used with caution during the last 6 months. About the same amount of Metronidazole passes into breast milk as is in the mother’s blood. Breast-feeding while taking this drug may cause side effects in your infant. If you must take Metronidazole, bottle-feed your baby. After you have finished your treatment, express any milk produced while you were taking the drug and discard it plus any pumped breast milk you might have saved. Nursing can be resumed 1 or 2 days after stopping Metronidazole.

Seniors

Seniors, particularly those with advanced liver disease, are more sensitive to the effects of this drug and may require less medicine. Follow your doctor’s directions and report any side effects at once.
