Questions to ask your pharmacist

• Does Cimetidine change how Melatonin works, or the other way round?
• Should I take Cimetidine and Melatonin 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.
