Planning a pregnancy. How long should you wait to get pregnant after being on clarithromycin? I took 2 biaxin XL pills 500 mg once daily for 10 days.

Clarithromycin: The elimination half-life of Clarithromycin was about 3 to 4 hours with 250 mg administered every 12 hours but increased to 5 to 7 hours with 500 mg administered every 8 to 12 hours.

A few days: This type of antibiotic works a little slower than the penicillin based types but eventually works well.

Much of the discomfort of otitis is caused by the pressure of the fluid/germ mix and take time to improve, regardless of treatment. Pain meds like Ibuprofen helps. ...Read more
