Metronidazole is a medication in a class of drugs known as antibiotics. According to Drugs.com, metronidazole is used to treat bacterial infections of the vagina, stomach, skin, joints and respiratory tract. It works by killing harmful bacteria in the body that cause these infections. Patients taking an antibiotic should take the medication for the entire time for which it is prescribed. Discontinuing use early may result in a return or worsening of infection. There are some side effects associated with metronidazole 150mg tablets.
Headache and Dizziness
Patients should use caution while operating a vehicle or completing tasks that may be dangerous until they know how metronidazole will affect them. If the headache becomes bothersome, consult a physician regarding the use of an over-the-counter medication such as acetaminophen for the occasional relief of headache. Headache or dizziness that occurs in conjunction with seizure may be a sign of a serious reaction to metronidazole and should be promptly reported to a doctor, says Drugs.com.
Stomach Pain and Discomfort
Additional symptoms can include nausea and diarrhea. Taking this medication with food or milk may help decrease these effects. Alcohol should be avoided during treatment with metronidazole. It may cause an increase in nausea and diarrhea and lead to additional complications. Eating smaller meals more frequently and adhering to a bland diet may help lessen stomach discomfort.
Vaginal Itching and Discharge
In some cases, vaginal itching and discharge may be symptoms of a vaginal yeast infection. During treatment with an antibiotic, some of the body's good bacteria are killed along with the bad bacteria. The lack of good bacteria in the intestinal tract creates an environment in the body susceptible to the growth of Candida, or yeast. Additional symptoms of a vaginal infection include itching, redness, burning, pain during intercourse, and a thick, white-colored vaginal discharge. Women who suspect they may have a vaginal yeast infection should consult their gynecologist. She may recommend the use of an over-the-counter or prescription vaginal cream for treatment.
