Always consult your veterinarian before administering doxycycline to your horse. Never exceed the prescribed dosage.
Avoid using doxycycline in pregnant or lactating mares due to potential fetal or neonatal effects. Similarly, exercise caution when treating young foals, adjusting dosages based on weight and veterinary guidance.
Doxycycline can interact with certain medications. Inform your veterinarian about all medications your horse is currently receiving. This includes supplements, as some may influence absorption or efficacy.
Monitor your horse for signs of gastrointestinal upset, such as vomiting or diarrhea. These side effects are relatively common but usually mild and transient. However, severe reactions should prompt immediate veterinary attention.
Photosensitivity is a potential side effect. Limit sun exposure for treated horses, particularly during peak sunlight hours. Provide shade and consider using sunscreen on unpigmented areas.

Doxycycline may affect kidney and liver function; your veterinarian should monitor these parameters, particularly in horses with pre-existing conditions. Adjustments to dosage may be necessary. Immediate veterinary attention is warranted for any signs of allergic reactions like hives or swelling.
