This service is a private, not an NHS service. There is a cost associated with any treatment through this service. The most popular medications include Viagra, Cialis, Levitra and generic Viagra (Sildenafil). They work by allowing better blood flow to the penis, by assisting the blood vessels that act as a gateway to open and stay dilated. Viagra-connect is licensed to be sold by the pharmacy without a need for a prescription to men over 18 years of age that suffer from erectile dysfunction. Currently, it is available in 50mg strength tablet in packs of 2s, 4s and 8s. One of our pharmacists will go through a short questionnaire in a private consultation room to ensure that the drug is safe and suitable for you.
