Azithromycin (Zithromax) is film-
coated, but it is ok to dissolve the
tablet in water. However, make sure you take the full dose. Also, next time, if you have problem swallowing, you can ask the pharmacist to dispense it as suspension for you.
Please make sure you finish the full course of antibiotic, even if you feel better after a few days of treatment.
Take care!
