Doxycycline Hyclate (Generic) Tablets, 100-mg

Doxycycline is a broad-spectrum antibiotic used to treat many diseases carried by ticks. Doxycycline is used to treat infections such as ehrlichiosis, Lyme Disease, Rocky Mountain spotted fever, salmon poisoning, toxoplasmosis, and leptospirosis.

The most commonly reported symptoms have included nausea and diarrhea, which are minor. Some pets may also suffer from loss of appetite, hair loss, lesions, mental confusion, and jaundice. If you observe more severe reactions like facial hives, swelling of the lips or tongue and difficulty breathing, immediately discontinue use and contact your vet, as these may be signs of an allergic reaction.

Talk to your vet about any other drugs the pet is taking before starting this medication.

Do not give Doxycycline to pregnant or nursing pets. Do not give multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after giving this medication, as these products can reduce the effectiveness of Doxycycline. Doxycycline may make a pet's skin more sensitive to sunlight and sunburn may occur. Throw away any unused medication when it expires or when it is no longer needed. Expired Doxycycline can cause a dangerous syndrome that can result in damage to the kidneys.

This drug is FDA-approved for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats.
