one week after starting have pain in pelvic and higher. Sharp pain. Discontinued medication at this time.

Second day i felt nasues.

The whole time I felt mildly dizzy, had very sharp pains in the stomach and severe vaginal itching, discharge and swelling. I will never take this again if I can help it.

No side effects. By the third day on the medication I started feeling so much better.

After 2 days of taking it I've got nausea, felt dizzy, have stomach pain, loss of appettite, hypertension, hot and cold spells, difficult to sleep. I have 7 more days of treatment.

It worked great for me

After second day of taking, started having dizzy spells, passed out, felt sick constantly

my son 5 years old was on cefzil and started experiencing wizzing,severe hives, took several days to feel better and the hives to stop popping up.

After a few days on this medication i started having diarhea at least 3 times per day and I still have it even after taking immodium and BIO-K yogurt.

This medicine has given me diaharra, two days after I was on it. Its been over a week and I still have it, several times a day or more! Very bad case, the worst I ever had before. Also I had a few days of dry vaginal itching (which is all I ever get when on an antibiotic) So yeah by far the worst...won't take again!! Other than that I am free from infection.

Was really tired and had an upset stomach. When I napped I had terrible dreams and would sleep for 2 hours at a time during the day, just exhausted. I'd had the sinus infection for several weeks, before going on the Cefzil, without the exhaustion. I was on it a day before the tiredness started.

I had a terrible reaction to this drug. I became short of breath, vomited continually & developed a skin rash. I had to go to the E.R. because of it.
