Femalegra 100 mg contains sildenafil 100 mg, it should be treated as a prescription medicine, particularly in India. India's drug rules require Schedule H medicines to be sold at retail only on the prescription of a registered medical practitioner. Femalegra 100 mg is a high sildenafil dose; Femalegra 100 mg  is generally the maximum recommended sildenafil dose in a 24-hour period, not a dose to exceed. If you tell me whether you're asking about buying/using Femalegra in India, I can check the specific product's regulatory status and whether 100 mg is appropriate.
