Always consult your veterinarian before administering Zithromax alongside other medications. Concurrent use with certain drugs can significantly alter their effectiveness or increase the risk of side effects.
Antacids: Administering Zithromax with antacids containing magnesium or aluminum hydroxide can reduce Zithromax absorption. Separate administration by at least two hours is recommended.
Digoxin: Zithromax can increase digoxin levels in the blood, potentially leading to toxicity. Careful monitoring of digoxin levels is necessary during concurrent therapy.
Warfarin: Zithromax may increase the effects of warfarin, increasing the risk of bleeding. Regular blood clotting tests are advised during combined use.
Erythromycin-based medications: Avoid concurrent use of other macrolides, such as erythromycin, as this may increase the risk of adverse events.
Theophylline: Zithromax can raise theophylline blood levels, potentially causing side effects. Regular theophylline monitoring might be needed.
Oral contraceptives: Some studies suggest potential interactions affecting oral contraceptive efficacy; discuss this with your veterinarian if using both.
This information is not exhaustive. Your veterinarian possesses detailed knowledge of your pet’s health and medication history, and can provide the most tailored and accurate advice on potential drug interactions.
