What should I discuss with my healthcare provider before taking doxycycline?
You should not take this medicine if you are allergic to doxycycline or to other tetracycline antibiotics such as demeclocycline (Declomycin), minocycline (Dynacin, Minocin, Solodyn, Vectrin), or tetracycline (Brodspec, Panmycin, Sumycin, Tetracap).
To make sure you can safely take doxycycline, tell your doctor if you have any of these other conditions:
If you are using doxycycline to treat gonorrhea, your doctor may test you to make sure you do not also have syphilis, another sexually transmitted disease.
FDA pregnancy category D. Do not use doxycycline if you are pregnant. It could harm the unborn baby or cause permanent tooth discoloration later in life. Tell your doctor right away if you become pregnant during treatment.
Doxycycline can make birth control pills less effective. Ask your doctor about using a non hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while using doxycycline.
Doxycycline passes into breast milk and may affect bone and tooth development in a nursing baby. You should not breast-feed while you are taking doxycycline.
Children should not use doxycycline. Doxycycline can cause permanent yellowing or graying of the teeth in children younger than 8 years old.
How should I take doxycycline?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Take doxycycline with a full glass of water. Drink plenty of liquids while you are taking doxycycline.
Different brands of doxycycline may have different instructions about taking them with or without food.
Most brands of doxycyline may be taken with food or milk if the medicine upsets your stomach.
Take Oracea or Periostat on an empty stomach, at least 1 hour before or 2 hours after a meal.
You may open a Doryx capsule or break up a Doryx tablet and sprinkle the medicine into a spoonful of applesauce to make swallowing easier. Swallow right away without chewing. Do not save the mixture for later use. Drink a full glass (8 ounces) of cool water right away.
Do not crush, break, or open a delayed-release capsule. Swallow the pill whole. Breaking or opening the pill may cause too much of the drug to be released at one time. The enteric coated pill has a special coating to protect your stomach. Breaking the pill will damage this coating.
Measure liquid medicine with a special dose measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose measuring device, ask your pharmacist for one.
Take this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Doxycycline will not treat a viral infection such as the common cold or flu.
If you need surgery, tell the surgeon ahead of time that you are using doxycycline. You may need to stop using the medicine for a short time.
Store at room temperature away from moisture and heat.
Throw away any unused medicine after the expiration date on the label has passed. Using expired doxycycline can cause damage to your kidneys.
