Doxymycin is the prescription brand name for the generic drug doxycycline. As of 2010, Doxymycin is not marketed within the United States. Doxymycin is an antibacterial drug used to treat certain types of infections such as gonorrhea, anthrax and urinary tract infections. Patients should be aware of the potential side effects of Doxymycin before beginning treatment with this antibiotic.
Increased Sun Sensitivity
Use of Doxymycin can increase a patient's sensitivity to sunlight, warn medical professionals with the Centers for Disease Control and Prevention. Patients exposed to sunlight while taking this antibiotic are at an increased risk of developing a red, irritated skin rash or sunburn. Severe skin reactions, such as peeling or blistering, should be reported to a medical professional as soon as possible. To limit sun sensitivity side effects, patients should protect their skin with clothing or sunblock before venturing outdoors.
Upset stomach side effects can arise after patients take a dose of Doxymycin, explain health professionals with SAEPI, or South African Electronic Packaging Inserts. These upset stomach side effects can include nausea, vomiting or diarrhea. Frequent bowel movements may be accompanied by abdominal cramping or bloating in certain patients. To limit the severity of upset stomach side effects, patients should avoid taking Doxymycin on an empty stomach.
Unusual body or facial swelling, a side effect called angioedema, can occur in certain people taking Doxymycin. Symptoms of angioedema can include chest discomfort, difficulty swallowing, and arm, leg, lip, tongue or throat swelling, warns PDRHealth. Patients who develop these side effects during treatment with Doxymycin should seek additional care from a medical professional.
Vaginal or Oral Thrush
Treatment with Doxymycin can alter the normal balance of naturally occurring bacteria within the body. A bacterial imbalance within the mouth can cause oral yeast infection symptoms, or thrush, in affected patients. Symptoms of an oral yeast infection can include the appearance of sores or white patches within the mouth or around the lips, explains Drugs.com. These oral skin lesions can be uncomfortable and may cause irritation or bleeding within the mouth. Additionally, women who take Doxymycin are at an increased risk of developing a vaginal yeast infection or vaginal thrush as a side effect of treatment. Symptoms of vaginal thrush include intense vaginal itching and unusually thick or white vaginal discharge. Patients who develop vaginal or oral thrush symptoms while taking Doxymycin should seek additional care from a doctor. Antifungal treatment is typically necessary to resolve vaginal or oral thrush symptoms.
