Sildenafil is a treatment for adult men (aged 18 years and older) with erectile dysfunction (also known as impotence), it contains the active ingredient, Sildenafil Citrate as found in Viagra. ED is when a man cannot get or keep an erection hard enough for satisfactory sexual activity. Perrigo Sildenafil contains the active ingredient sildenafil. It belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors.
It works by relaxing the blood vessels in your penis, allowing blood to flow into your penis when you get sexually excited and causing an erection.
Perrigo Sildenafil will only help you to get an erection if you are sexually excited (stimulated).

The key psychological factors are stress, anxiety, depression, sexual boredom and relationship struggles. Take one tablet, as needed, approximately 1 hour before sexual activity; Do not take more than one tablet a day You will not get an erection just by taking Sildenafil. This medicine will only help you get an erection if you are sexually aroused. You and your partner should engage in foreplay just as you would if you were not taking a medicine for erectile dysfunction. The amount of time this medicine takes to work varies from person to person, but it normally takes between 30 to 60 minutes to work. You may take it up to 4 hours before sexual activity. If you are not successful the first time, try to have sex again, but remember you can only take 1 tablet a day. For most men, Sildenafil will work the first or second time they try it. If it has been some time since you were able to get or keep an erection, it may take a couple of attempts before you are able to achieve an erection. If you feel the effect of Sildenafil is too strong or too weak, talk to your pharmacist or doctor.
