Caverject is an injectable medication used to help erectile dysfunction in older men. Caverject improves blood flow directly to the penis to help achieve and maintain an erection.

It is important that you read all the paper work and instructions given to you by your pharmacist and follow the doctors instructions on how to inject Caverject. Make sure to sterilize the injection side with rubbing alcohol and apply pressure to avoid bruising after you inject your dose of Caverject. Make sure to change injection areas for each dose to avoid skin problems on the penis. 

Dosage will be decided by your doctor while also considering your response to the treatment. Follow the dosing instructions explicitly when injecting Caverject. Once injected you should feel the effects within five to twenty minutes and be able to maintain an erection for about an hour.

You will need to learn how to store and dispose of needles while taking Caverject. Speak with your pharmacist on ways to use Caverject safely. 

Inspect Caverject for any discoloration or floating particles before injecting, and avoid use if there is discoloration in the liquid. 

Alprostadil is the generic name for Caverject and is able to induce an allergic reaction. Check with your doctor for any known allergies, medication or supplementation you are taking before knowing if Caverject is right for you.
