DORYX® is a prescription oral antibacterial drug that is used in combination with other medicines to treat severe acne. Prescription DORYX® can also be used for the treatment of urethral or endocervical Chlamydia infections. You should use DORYX® only as directed by your doctor to reduce the chance that bacteria will become resistant to this antibacterial drug and similar drugs.
Do not take DORYX® if you are allergic to tetracyclines. Like other tetracyclines, doxycycline can harm an unborn child when taken by a pregnant woman. Talk to your doctor if you are pregnant or are breastfeeding. DORYX® should not be used when a child’s teeth are forming (during the last half of pregnancy and up to the age of 8 years) because it may cause permanent darkening of teeth. Oral contraceptives may not work as well when you are taking DORYX®.
Diarrhea may occur with the use of antibacterial drugs and may range from mild to severe. If you develop watery and bloody stools (with or without stomach cramps or fever) even as late as two or more months after having taken the last dose of DORYX®, please call your doctor as soon as possible.
Sensitivity to natural or artificial sunlight can occur with tetracycline-class drugs. Avoid excessive sunlight and consider using sunscreen or sunblock. Stop taking DORYX® and call your doctor if you develop a severe sunburn.
The most common side effects seen in patients taking tetracyclines include anorexia, nausea, vomiting, diarrhea, rash, sensitivity to sunlight, hives, and low red blood cell count (anemia). The most common side effects in patients taking DORYX® for the treatment of urethral or endocervical Chlamydia infections were nausea, vomiting, diarrhea, and vaginal infection.
