Precautions While Using This Medicine

If your symptoms do not improve within a few days, or if they become worse, check with your doctor.

Drinking alcoholic beverages while taking this medicine may cause stomach pain, nausea, vomiting, headache, or flushing or redness of the face. Other alcohol-containing preparations (for example, elixirs, cough syrups, tonics) may also cause problems. These problems may last for at least a day after you stop taking metronidazole. Also, this medicine may cause alcoholic beverages to taste different. Therefore, you should not drink alcoholic beverages or take other alcohol-containing preparations while you are taking this medicine and for at least 3 days after stopping it .

Metronidazole may cause dryness of the mouth, an unpleasant or sharp metallic taste, and a change in taste sensation. For temporary relief of dry mouth, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.

This medicine may also cause some people to become dizzy or lightheaded. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert . If these reactions are especially bothersome, check with your doctor.

If you are taking this medicine for trichomoniasis (an infection of the sex organs in males and females), your doctor may want to treat your sexual partner at the same time you are being treated, even if he or she has no symptoms. Also, it may be desirable to use a condom (prophylactic) during intercourse. These measures will help keep you from getting the infection back again from your partner. If you have any questions about this, check with your doctor.
