For Bronchitis "Within 36 hrs, symptoms started to subside. Had no side effects with stomach (take with food). I suffer from bronchitis about twice a year. This medication was much more effective than Z-packs, Amoxicillin, or Cipro. I started getting mild headaches around day 4. Felt better but didn't clear up cough and wheezing."

For Sinusitis "I have been on this for 5 days, sort of working, still have the headache though. I haven't really had any side effects yet. But I was given a 21-day dosage for (2) 300 mg capsules. I have had 4 sinus infections since January. Hope it helps get rid of the headache. It has helped with the drainage and coughing though."

For Pneumonia "Let's talk about my sickness first. I was dipping myself into a freezing water pool for approximately 5 minutes a day. The next morning, I felt the weather was so much colder, so I knew it was a fever. I'm a very healthy person, I make sure that my body is clean. I drink a lot of water and cleaning drinks, so my stomach is always clean. The doctor prescribed me Fevadol and Omnicef. The Omnicef experience was horrible. Very bad diarrhea every 15 minutes or so, even if there was nothing in my body. I couldn't sleep for more than 24 hours with complete alertness and no feeling of exhaustion. Eating it without food will make it worse. I used it for 2 days only. The dosage was 300 mg twice a day. I got dizziness, back pain, headache, and diarrhea."

For Sinusitis "This medicine made me feel worse than the original symptoms. I usually have a high tolerance for meds, don’t usually get dizzy or feel nauseous ever. But this medicine made me feel as if I was suffering from being hungover. I would drive 8 hours later after taking the meds and would feel like I could black out whenever. I would randomly feel nauseous. The headaches were a constant theme. Now that I’ve read the comments, I can attribute some of the diarrhea I had to it. I went back to the doctor and was prescribed Doxycycline, so I’m on day 4 and I feel better but still suffer from a cough."
