How does Caverject work?

Alprostadil, the active principle of Caverject, is a prostaglandin E1. Prostaglandin E1 is a substance administered directly to the corpora cavernosa which inhibits the vasoconstrictive activity of the penis, causing the smooth muscle to relax and more blood to flow to the penis producing an erection.

Why switch to Caverject?

Being the only molecule authorized by the FDA to be injected by the patient himself into the penis, Alprostadil proves with its efficacy and safety to be a reliable alternative in the treatment of erectile dysfunction. Patients who have tried other methods without satisfactory results or have contraindications, find in Caverject a cost-effective and direct option, without interaction with drugs or alcohol, and without the need for prior sexual stimulation to achieve an erection.

How to use and dosage of Caverject:

The way Caverject is administered must be explained by a health professional before it can be used at home and self-injected by the patient.

The first step is the preparation of the medication: if you have purchased Caverject in vials, you must use the larger caliber needle to insert the solvent into the vial containing Alprostadil powder, and shake until it is properly diluted. Once it is well mixed, aspirate it again with the large calibre needle. To administer, carefully change the needle to the smaller size (usually labeled 27 to 30).

Caverject should be administered directly to the corpora cavernosa of the penis, with one on each side of the stem. After being naked and in a comfortable position, use an alcohol wipe to clean the area to be injected. Then, hold the penis with your thumb and forefinger forming a “bulging” area to inject into the corpora cavernosa, avoiding visible veins or blood vessels. At a 90-degree right angle, insert the needle and gently push the fluid in. If you notice any resistance, move the needle or move it slightly. Massage the penis so that the medication is well distributed, and within 5 to 10 minutes, there should be an erection.

The dose of Caverject should be individualized for each case. Usually, the dose adjustment is made from 2.5 mcg by the doctor, until a satisfactory erection is achieved, and can be increased if there is no response of 5 to 10 minutes; or decreased if the erection is prolonged for more than one hour, which is highly discouraged.

The use of a single injection of Caverject per day is recommended, and no more than two to three injections per week. Each injection should be separated from the previous injection for at least 24 hours.

Isaverject effective every time it is used?

Because it is a medication that acts directly on the penis, Caverject is usually quite effective if used with the right dose for each case. Of course, the tolerability and demand of each organism is different, and multiple factors can influence its effectiveness.

With administrations higher than recommended, no overdose was observed in clinical trials with Alprostadil. However, systemic effects common to prostaglandin E1 toxicity could occur. If this is the case, you should contact the emergency department immediately for treatment of each systemic symptom and monitoring until it is resolved.

In case of prolonged erection due to overdose, the patient should remain in the medical service until detumescence of the penis occurs.
