Doxycycline is a common treatment for Lyme disease in horses. The typical dosage is 5-10 mg per kilogram of body weight, administered orally once or twice daily. This dosage should be given for at least 21-28 days, depending on your veterinarian’s recommendation and the horse’s response to treatment. Always follow your vet’s instructions precisely.
Factors Influencing Dosage
Your veterinarian will consider several factors when determining the appropriate doxycycline dosage for your horse. These include the severity of the infection, the horse’s overall health, and potential drug interactions. Weight is a key consideration; accurate weight measurement is critical for correct dosage calculation. Pre-existing conditions and age can also influence treatment decisions.
Monitoring Treatment
Regular monitoring is necessary throughout the treatment period. Your vet will likely recommend blood tests to assess the effectiveness of the doxycycline and monitor for any adverse reactions. Observe your horse carefully for any signs of improvement or worsening symptoms. Report any unusual changes to your veterinarian immediately.
Doxycycline Administration and Side Effects
Doxycycline is usually administered orally, often mixed with feed to improve palatability. While generally well-tolerated, potential side effects include gastrointestinal upset (vomiting, diarrhea), loss of appetite, and photosensitivity. Less common side effects may occur. Immediate veterinary attention is needed if you notice any serious side effects.
