Hi and thanks for posting. An in person exam with a veterinarian or valid veterinary client patient relationship is needed in order to get any prescription. Unfortunately these can't be prescribed online for legal reasons. You can try the over the counter flea and tick preventatives but they do not always work very well. The one over the counter flea and tick medication that I would recommend over the others is Frontline Gold. I hope this helps!
