Tetracycline is an antibiotic medication. It works by killing harmful bacteria in the body. According to Drugs.com, tetracycline is used to treat many different bacterial infections, such as urinary tract infections, acne, gonorrhea, chlamydia and others. Patients who are prescribed tetracycline should take their medication for the entire duration for which it is prescribed, as stopping treatment early may cause a return or worsening of infection. Side effects are associated with tetracycline use.
Photosensitivity
Photosensitivity may occur in patients taking tetracycline. Photosensitivity is an increased sensitivity to the sun. Those taking tetracycline should avoid being outdoors in the direct sunlight and should abstain from the use of tanning beds and/or sunlamps. Wearing protective clothing and sunblock can help prevent sunburn while taking this medication.
Stomach Discomfort
Patients taking tetracycline may develop stomach discomfort. Symptoms can include mild nausea, vomiting, diarrhea or stomach upset. This medication should be taken on an empty stomach and at least 1 hour before or 2 hours after meals, reports Drugs.com. Small dietary changes such as adherence to a bland diet and eating small meals spaced throughout the day may help to alleviate such symptoms. Patients who develop severe or persistent vomiting or diarrhea may be at risk for dehydration and additional complications; in such cases, medical attention should be sought.
Yeast Infections
Vaginal itching and discharge may occur while taking tetracycline. These symptoms may indicate a vaginal yeast infection. While tetracycline works by killing harmful bacteria in the body, it also kills some of the body's good bacteria. This may lead to an overgrowth of candida, or yeast. Taking a daily probiotic supplement or eating foods higher in natural probiotics, such as yogurt or kefir, may help to prevent or lessen the severity of a vaginal yeast infection. Tetracycline also lessens the potency of oral contraceptives, so while women are taking tetracycline, other forms of birth control should be used.
