the answer is no absolutely not. first of all three days may not be long enough to determine whether or not the biaxin (clarithromycin) is effective or not. you need to complete the full course of antibiotics. take all the pills exactly as prescribed. you may still be experiencing some symptoms even after you take the last pill but symptoms may clear up within a few days after you finish the prescription. if they don't consult your health care provider. a z-pack is a kit of azithromycin which is the same class of antibiotic as biaxin (clarithromycin). combining these two medications can cause serious side effects. do not do it. in fact no one should self-dose with prescription medications. and why do you have an extra z-pack lying around? careless use of antibiotics is what's driving the rise in so-called "superbugs " or bacteria that don't respond to antibiotics. mrsa is one such bacterium. you should always take an antibiotic exactly as prescribed and be sure to take all the pills. if you have any other questions i suggest you consult your health care provider. i was given biaxin for a chest cold and i got worse instead of feeling better went to my dr immediately and found out that i was allergic to biaxin it inflamed my chest was put on something else and felt better within 12 hrs.
have a killer head & chest upp resp inf for 3 days & biaxin is not helping. i have a zpack can i take both at once?
