They are similar: There are several available--lamisil, lotrimin, tinactin (tolnaftate) etc..Are similar in efficacy. You don't really need strong, just have to be the right medicine. The strength available are appropropriate/adequate to treat commom skin fungal/ringworm infections (not beard/scalp areas). If not better in about 2 wks, consult doc for proper diagnosis/treatment. Good luck.
