"Have taken antibiotics, and this is the only one that makes me feel nauseous. I take it with food because otherwise I couldn’t handle it. Two tablets a day until finished. On my forms from the pharmacy, it said nothing about avoiding dairy products! Will persevere."

"Completed 2-week 50 mg bid dosage; still occasionally cough up yellowish/green phlegm. Doctor said to take with food to avoid upset stomach, yet one reviewer says doctor told her to take 2 hours before or after food. Hers worked; mine seemingly didn't. Some stomach cramping and constipation."

"Very bad side effects. I had to stop after the second pill. After reading the possible side effects, I am wondering how this drug got approved. It can kill you in more than one way or make you blind. Ask your doctor for an alternative."

"I had a chest with mucus, so was given doxy, which improved me through the day. I also took Allegra D, so don't know if it was the doxy or Allegra D that was the one that improved me (or both)."
