Doxycycline is also used to treat blemishes, bumps, and acne-like lesions caused by rosacea. Doxycycline will not treat facial redness caused by rosacea.
Some forms of doxycycline are used to prevent malaria, to treat anthrax, or to treat infections caused by mites, ticks, or lice.
Doxycycline may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking Mondoxyne NL (doxycycline)?
You should not take this medicine if you are allergic to doxycycline or other tetracycline antibiotics such as demeclocycline, minocycline, tetracycline, or tigecycline.
To make sure doxycycline is safe for you, tell your doctor if you have:
asthma or sulfite allergy;
a history of increased pressure inside your skull;
if you also take isotretinoin (Amnesteem, Claravis, Sotret); or
if you take seizure medicine (carbamazepine, phenobarbital, phenytoin), or a blood thinner (warfarin, Coumadin, Jantoven).
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.
Taking this medicine during pregnancy may affect tooth and bone development in the unborn baby. Taking doxycycline during the last half of pregnancy can cause permanent tooth discoloration later in the baby's life. Tell your doctor if you are pregnant or if you become pregnant while using this medicine.
Doxycycline can make birth control pills less effective. Ask your doctor about using a non-hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy.

Doxycycline can cause permanent yellowing or graying of the teeth in children younger than 8 years old.

If you take doxycycline to prevent malaria: Start taking the medicine 1 or 2 days before entering an area where malaria is common.
