I am board certified in family medicine. I believe D.A. gave sound advice, but I would suggest staying away from clindamycin as about 20 percent of people who take it get C. Diff. collitis.
I have several patients who have been successful in purchasing medications through AlldayChemist.com. Typically, at 75 to 90 percent savings of the U.S. price. Keep up the good work. - J.W.
