Zindaclin is used to treat acne spots. The medication contains clindamycin phosphate, which breaks down in the skin to clindamycin and is antibiotic. Zindaclin helps reduce the number of bacteria present and this, in turn, helps to prevent the pores from becoming blocked and new spots forming. The symptoms you've mentioned (double vision, slurred speech, drowsiness, vomiting, etc.) are some possible side effects of zolmitriptan. You may consult a dermatovenerologist and psychiatrist for each of the problems you are experiencing.
