Can I take Cloxacillin with Doxycycline?

Drug Interactions Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracyclines in conjunction with penicillin.

This is general interaction text from the label of a product that contains Doxycycline. It does not mention Cloxacillin, so it does not show how Cloxacillin and Doxycycline affect each other. The verdict above comes from the GoDavaii interaction dataset. Ask your pharmacist to check both medicines' labels before you combine them.

Questions to ask your pharmacist

• Does Cloxacillin change how Doxycycline works, or the other way round?
• Should I take Cloxacillin and Doxycycline at different times of day?
• Which side effects should I watch for while taking both?
• Is there a better option if this combination does not suit me?

• Always tell your doctor/pharmacist about ALL medicines you take - prescriptions, OTC, supplements, and herbal products.
• Keep a current medicine list with doses and timings - photo on your phone is enough.
• Read medicine labels for timing (with food / empty stomach) before combining.
• Even 'safe' combinations need monitoring - note any unusual symptoms in the first few days.
• Use GoDavaii AI to double-check before adding any new medicine, supplement, or desi ilaaj.
