Doxycycline Basics

Doxycycline is a broad-spectrum tetracycline antibiotic used to fight infections. Some infections that respond well to doxycycline include urinary tract infections, respiratory infections, blood-borne infections, wound infections, and tick-borne diseases. Doxycycline treats tick-borne bacterial diseases, like Rocky Mountain spotted fever, lyme disease, and ehrlichiosis. It is also treats water-borne infections such as leptospirosis. Doxycycline slows down bacterial growth by inhibiting protein synthesis in susceptible organisms, resulting in their death.

This medication requires a prescription from your veterinarian. Doxycycline Monohydrate is available in 50mg tablets, 100mg tablets, and 100mg capsules, while Doxycycline Hyclate is available in 50mg capsules and 100mg tablets.

Doxycycline Directions

Give as directed by your veterinarian. Follow the instructions printed on the prescription label. Be sure to complete the prescription to ensure a full recovery, even if your pet seems to be improving, unless instructed otherwise by your veterinarian. Dosage and duration depend on the condition being treated and response to the medication. Allow your pet access to plenty of water. Give with or without food but do not give with dairy products. In the case of a missed dose, give it as soon as you remember or wait until it is time to give the next dose. However, do NOT give a double dose, as this can lead to an overdose.

Store at room temperature, protected from light and moisture.

Doxycycline Warnings

Keep out of the reach of children and pets. Do not use in animals with a known sensitivity to doxycycline. Also, do not use in pregnant animals. Let your veterinarian know if your pet is on any other medications, as interactions with certain medicines can occur. Do not administer any calcium-containing medications, antacids, laxatives, or multivitamins within 2 hours of the last doxycycline dose. Notify your veterinarian if your animal suffers from kidney or liver disease. This medication may increase skin’s sensitivity to sunlight.  If you notice any behavioral or physiological changes in your pet while administering this medication, contact your veterinarian immediately.

Allergic Reactions and Serious Side Effects

Allergic reactions and serious side effects are rare, but in the case of an allergic reaction or a serious side effect you should stop doxycycline treatment and seek veterinary attention. Some common signs of allergic reactions and serious side effects are: hives, breathing difficulty, facial swelling, loss of appetite, or dark colored urine. Symptoms of an overdose may include vomiting, nausea, and diarrhea.
