Sinusitis
"Wrote on here yesterday. Just updating. Doc advised me to stop taking clarithromycin after I took only one 500mg last night. My experience- awful taste in mouth, vomiting, lower back pain, aching all over, severe stomach pain, couldnt sleep, dizziness, severe anxiety, dull heavy headache (similar to a hang over) and very dry mouth. All this after only ONE tablet. This medication is EVIL! Take with extreme caution people. Good luck x"
