Viagra is a tablet to be taken as and when needed. When sex drive or erectile disfunction problems arise, Viagra will ensure erections for up to 4 hours when stimulated. Sometimes when the right moment comes at the wrong time – unexpected interruptions, distractions, surprises/events can derail your romantic moment or plan but with Viagra you will be rock hard and ready for action with a quality erection. Safe for diabetics, if you have had a prostatectomy (removal of the prostate) it will improve your ability to get and maintain an erection regardless of age, weight etc.
Up to 4 hours.
2 to 3 days from your last tablet - all traces will be out of your system for the purpose of drug testing/urine/blood samples.
25 to 100mg, 30 minutes before sexual activity. Will last up to 4 hours.
