Can I take Ciprofloxacin and Doxycycline together?

Why this happens

Both are antibiotics but they work in different ways. Doxycycline stops bacteria from growing (bacteriostatic), while ciprofloxacin actively kills them (bactericidal). In some cases, stopping the growth can make the 'killing' antibiotic less effective, though this is rarely a problem in clinical practice. Both drugs also share a side effect of making your skin more sensitive to UV light.

What you should do

You can take these together if your doctor has specifically prescribed both. Ensure you wear high-factor sunscreen and protective clothing, as both drugs increase your risk of severe sunburn. If you experience severe diarrhoea or stomach pain, contact your doctor immediately. Take them at least 2 hours apart from any antacids, dairy, or iron supplements, as these can stop both medicines from being absorbed properly.
