Monodox Drug Center

Monodox (doxycycline monohydrate) is used to treat many different bacterial infections, such as urinary tract infections, acne, gonorrhea, and chlamydia, periodontitis (gum disease), and others. It is also used to treat blemishes, bumps, and acne-like lesions caused by rosacea (but will not treat facial redness caused by rosacea). Monodox is a tetracycline antibiotic. This medication is available in generic form. Common side effects include stomach upset, diarrhea, nausea, or vomiting.

The usual adult dose of Monodox is 200 mg on the first day of treatment (100 mg every 12 hours or 50 mg every 6 hours), and a maintenance dose of 100 mg/day. The maintenance dose may be taken as a single dose or as 50 mg every 12 hours. The recommended dosage for pediatric patients weighing 100 pounds or less is 2 mg/lb of body weight divided into two doses on the first day of treatment, followed by 1 mg/lb of body weight given as a single daily dose or divided into two doses, on subsequent days. Monodox may interact with cholesterol-lowering medications, isotretinoin, tretinoin, antacids, bismuth subsalicylate (e.g., Pepto-Bismol), blood thinners, penicillin antibiotics, or minerals such as iron, zinc, calcium, magnesium, and over-the-counter vitamin supplements. Tell your doctor all medications and supplements you are taking. Monodox is not recommended for use during pregnancy. It may harm a fetus. Use reliable forms of birth control while taking this medication. This drug passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breast-feeding.
