Avidoxy

Name: Avidoxy

Avidoxy Overview

Doxycycline is a prescription medication used to treat certain bacterial infections and to prevent malaria infections. Doxycycline belongs to a group of drugs called tetracycline antibiotics, which prevent the growth and spread of certain bacteria by inhibiting protein production.

This medication comes in tablet, capsule, and oral suspension (liquid) forms, and is typically taken once or twice a day. The tablets and capsules should be taken with a glass of water, with or without food. However, taking doxycycline with milk or food may decrease the amount of medication absorbed from your stomach. Do not crush or break the delayed-release tablets or capsule.

Doxycycline also comes as a gel to be administered by a dentist in a clinic setting.

This medication is also available in an injectable form to be given directly into a vein (IV) by a healthcare professional.

Common side effects of doxycycline include nausea, sunlight sensitivity, and rash.

What is Avidoxy (doxycycline)?

Doxycycline is a tetracycline antibiotic that fights bacteria in the body.

Doxycycline is used to treat many different bacterial infections, such as acne, urinary tract infections, intestinal infections, eye infections, gonorrhea, chlamydia, periodontitis (gum disease), and others.

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 Avidoxy (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 ever had:

  • liver disease;

  • kidney disease;

  • asthma or sulfite allergy;

  • increased pressure inside your skull; or

  • if you also take isotretinoin, seizure medicine, or a blood thinner such as warfarin (Coumadin).

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 pass into breast milk and may affect bone and tooth development in a nursing infant. Do not breast-feed while you are taking doxycycline.

Doxycycline can cause permanent yellowing or graying of the teeth in children younger than 8 years old. Children should use doxycycline only in cases of severe or life-threatening conditions such as anthrax or Rocky Mountain spotted fever. The benefit of treating a serious condition may outweigh any risks to the child's tooth development.
