General & Family Physician 's  Response
Hello,
CAVERJECT( ALPROSTADIL ) is a prostaglandin and is used to dilate the blood vessels in muscles of penis,so that there is increased flow of blood in penis resulting in engorgement of penis which ultimately causes hardness and erection of penis.
You get erection in 10-15 minutes after the injection and the effect lasts for appox.one hour.
You have to make sure that you dont consume more drug so as to avoid persistent erection lasting beyond 4 hours becausebsuchna situation may result in permanent damage of muscles and permanent erectile dysfunction.
As far as your dose is concerned,you may take higher dose of 7.5mg,provided your erection is lasting much less than 1 hour with present dose.
You may discuss with your doctor about this.
Thanks
