USES: Doxycycline is an antibiotic used to treat a wide variety of bacterial infections. This antibiotic only treats bacterial infections. It will not work for viral infections (e.g., common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
HOW TO USE: Take each dose with a full glass (8 ounces or 240 milliters) of water unless your doctor directs you otherwise. Do not lie down for 30 minutes after taking this drug. Take with food or milk if stomach upset occurs unless your doctor directs you otherwise. Take this medication 2-3 hours before or after taking any medications containing magnesium, aluminum, or calcium. Some examples include quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), vitamins/minerals, and antacids. Sucralfate, bismuth subsalicylate, iron, and zinc are also included. These medications bind with doxycycline preventing its full absorption. The liquid suspension form of this medicine must be shaken well before using. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Do this by taking the medicine at evenly spaced intervals throughout the day and night. Continue to take this medication until the full prescribed amount is finished even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow resulting in a relapse of the infection.
SIDE EFFECTS: This medication may cause stomach upset, diarrhea, nausea, headache or vomiting. If these symptoms persist or worsen, notify your doctor. Very unlikely but report: stomach pain, yellowing of the eyes or skin, vision changes, mental changes. Doxycycline increases sensitivity to sunlight. In the unlikely event you have an allergic reaction to this drug, seek immediate medical attention. Symptoms of an allergic reaction include: rash, itching, swelling, dizziness, trouble breathing. If you notice other effects not listed above, contact your doctor or pharmacist.
