tonsillitis/pharyngitis
"I'm not allergic to penicillin, but was given Clarithromycin due to a very severe antibiotic-resistant bout of tonsillitis. I'd been suffering for weeks taking antibiotics that didn't work, but literally after the first tablet, I noticed a difference. Works VERY well. However, these are not particularly good tablets to take when you have swollen tonsils because they are huge tablets - I had to cut mine up and swallow them in 4 pieces. Also, I've noticed some side effects: I have diarrhoea (not too badly, but it makes life a bit more difficult), wind, and the taste in my mouth is constantly bitter. But overall, a very good medicine!"
