Tetracycline antibiotics are used to treat certain infections such as chlamydia, as well as for the long-term treatment of acne.
Drugs in this family include
- demeclocycline hydrochloride (Declomycin)
- doxycycline (Bio-Tab, Doryx, Doxy-Caps, Doxychel, Monodox, Periostat, Vibramycin, Vibra-Tabs)
- minocycline hydrochloride (Dynacin, Minocin, Vectrin),
- oxytetracycline hydrochloride (Terramycin, Uri-Tet),
- tetracycline hydrochloride (Achromycin V, Panmycin, Robitet, Sumycin, Teline, Tetracap, Tetracyn, Tetralan)
- and others
Take at a Different Time of Day
Numerous minerals, including aluminum (found in many antacids), bismuth (in Pepto-Bismol),
The reason is the minerals and the drugs attach to each other and form insoluble chemicals that simply pass out of the digestive tract. The best solution is to avoid taking supplements that contain these minerals within the 2 hours before or after your dose of tetracycline medication.
Possible Harmful Interaction
Tetracycline antibiotics have been reported to cause increased sensitivity to the sun, amplifying the risk of sunburn or skin rash. Because St. John's wort and dong quai may also cause this problem, taking these herbal supplements during tetracycline treatment might add to this risk.
It may be a good idea to wear a sunscreen or protective clothing during sun exposure if you take one of these herbs with a tetracycline antibiotic.
