Caverject is a sexual enhancer that treats male erectile dysfunction symptoms. It contains the active ingredient alprostadil.
Areas of application for Caverject
Caverject is an injection preparation used to treat erectile dysfunction (impotence) in adult men. It is used for erectile dysfunction of a physical or psychological nature. The sexual enhancer is injected directly into the erectile tissue of the male member.
The increase in blood flow in the penis leads to an erection during sexual arousal. A medical check-up must take place every three months if the sexual enhancer is administered regularly. Caverject is also used as an infusion for the treatment of pronounced arterial circulatory disorders in the case of chronic stage III or IV arterial occlusive disease. This disease is caused by calcification of the blood vessels, which in turn causes blood flow disorders and pain in the limbs. During the treatment, the doctor controls the condition of the vessels.
Another indication is lung malformations or congenital heart defects in babies. The newborns receive an infusion with the active ingredient in their arteries or veins for a short time. This procedure improves oxygenation until surgery can be performed.
In addition, Caverject serves as an aid to diagnose erectile dysfunction as part of medical examinations.
The potency-enhancing effect of Caverject goes back to the drug alprostadil. Alprostadil is also known as prostaglandin E1 and is an endogenous substance. It belongs to the group of prostaglandins.
Alprostadil has the property of dilating and relaxing the blood vessels within the penis. This makes it easier for the blood to flow into the erectile tissue. This process leads to a strong erection. Alprostadil’s mechanism of action differs from that of PDE-5 inhibitors such as Cialis or Viagra. For this reason, Caverject is also effective in the case of erectile dysfunction due to nerve impairment.
Caverject is primarily administered as a solution for injection. The active ingredient, alprostadil is also available as a urethral stick or in the form of a cream. In addition to Caverject, the alprostadil preparations are also available under the trade names:
- MUSE as a urethral rod
Normally, a Caverject injection solution is freshly mixed at home. Then the injection is made directly into the erectile tissue of the penis via syringe. The procedure is also known as SKAT (cavernosal autoinjection therapy).
MUSE urethral sticks are administered through an applicator that is inserted directly into the urethra where they dissolve.
How effective is Alprostadil?
The success rate of alprostadil with an injection or with the use of urethral rods varies between 62 and 93 percent. Injections are considered more effective than urethral sticks. However, the side effects are higher for them.
In principle, however, the effect of alprostadil is weaker than that of the PDE-5 inhibitors. Caverject has the advantage of not being dependent on sexual stimulation. Therefore, it also works in men where PDE-5 inhibitors are unsuccessful.
Caverject is injected directly into the erectile tissue of the penis. The attending physician determines the dose individually, which is usually 2.5 to 20 micrograms. Treatment is usually started with the lowest dose first.
It usually takes 10 to 30 minutes for the effects to kick in. Before the user can prepare and use the injection technique and injection solution by himself, the doctor must provide a thorough explanation. During the therapy, the doctor also regularly monitors its progress.
Is there a risk of injury?
Some patients are concerned that the unusual form of administration via syringe could cause injury to them. It is all the more important that the patient learn how to use it from the doctor. The doctor will also set the appropriate dose before issuing an appropriate prescription.
If there are any questions, it is advisable to clear them up by talking to the doctor. In most cases, after thorough training, the patients master the handling of the syringe well. Injuries to the penis are very rare. In most cases, these are just bruises that heal quickly. However, it is important not to give the injection while under the influence of alcohol or drugs, as this increases the risk of injury.
If, for health reasons, the patient’s fine motor skills are impaired or the patient has visual difficulties, it is also possible for the sexual partner to administer the drug if appropriate training has taken place beforehand under the supervision of a doctor.
Caverject is not suitable for use if there is an allergy to the active ingredient alprostadil or one of the excipients. The same applies if a penile prosthesis is present, if sexual activity is harmful to health or if diseases such as leukemia (blood cancer), bone marrow cancer or sickle cell anemia are present.
