Some examples include antacids, didanosine solution, quinapril, vitamins/minerals, dairy products (such as milk, yogurt), and calcium-enriched juice. These products bind with doxycycline, preventing your body from fully absorbing the drug.

Continue to take doxycycline daily while in the malarious area. Upon returning home, you should keep taking doxycycline for 4 more weeks. If you are unable to finish this course of doxycycline, contact your doctor.
If you are using the liquid form of doxycycline, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.
