Vidalista Professional , it is currently listed by an Indian pharmaceutical supplier as a tadalafil 20 mg sublingual product and is supplied internationally. For legal availability in India, the important distinction is between a product being advertised/supplied by an Indian company and being legally authorized for retail sale in India. Indian drug rules require prescription medicines covered by Schedule H to be sold by retail only on a prescription from a registered medical practitioner. I could not verify from the official CDSCO sources that the specific brand “Vidalista Professional” has a current Indian marketing authorization. So I wouldn't assume that every online listing means the product is legally approved for domestic retail sale. If you're looking for a legally available tadalafil alternative in India, prescription tadalafil products are available through licensed pharmacies; for example, Tata 1mg currently lists Vidalista 20 mg as a prescription product.
