General Information On Caverject

Caverject (generic name: Alprostadil) is a medicine used for treating erectile dysfunction caused due to psychogenic, vasculogenic, neurogenic, or mixed etiology. Alprostadil is a prostaglandin, which works by encouraging the flow of blood to the penis so that an erection is achieved and maintained. You can buy Caverject in the form of 6.15, 11.9, 23.2 and 46.4 mg intracavernosal vials. This drug should not be used by men with penile implants and cannot be used by children or women. Caverject can also be used in diagnostic tests for detecting erectile dysfunction.

Side Effects for Caverject

Mild pain, slight bleeding and irritation at the injection site are likely to surface after Caverject is administered. Most of these side effects subside as your body gets used to the drug, but if the situation becomes intolerable, you should inform your doctor immediately. You should be careful if you notice redness, swelling or tenderness on the penis, or if you see unusual curving or lumps in the penis. Sometimes, you may have a prolonged and painful erection for as long as 4 hours. If this happens, you should immediately stop using Caverject and seek medical help. Other than the above side effects, some patients may also complain of hypertension, headache, dizziness, back pain, sinusitis, nasal congestion, cough, and trauma. Continued use of Caverject may also result in prostatic disorders in the patient.


Before taking Caverject, you should inform your doctor if you are allergic to Alprostadil or to any active or inactive ingredients in the medicine. You should also tell your doctor if you are suffering from a penis condition like fibrosis, scarring, angulation, or Peyronie’s disease, and blood cancers like multiple myeloma, leukemia, or sickle cell anemia. You should remember that Caverject does not provide protection against diseases like Hepatitis B, syphilis, gonorrhea, or HIV, and therefore, you should use a barrier form of contraception like condoms while on this drug. As Caverject causes dizziness, you should not perform any activity which requires complete alertness, such as driving a vehicle or operating a machine.

Caverject Dosage

Caverject treatment usually starts off with Caverject 2.5mg, which can be increased up to Caverject 140mg depending on the patient’s condition and his response to treatment. However, most patients do not need to take 140mg, and many respond well to Caverject 40mg. You should not stop using the drug if you feel that your symptoms have been relieved, and you must also not use Caverject for a longer period than prescribed, as it will not help you more.


Before your doctor advises you to buy Caverject, you should tell him/her if you are taking blood thinners like heparin or warfarin. As the drug causes dizziness, you should not take along it with sedatives, sleeping pills, antidepressants, anti-anxiety medicines, anti-seizure medicines, and narcotic pain relievers. Other than the above drugs, you should inform your doctor about all the medicinal products you are using at present, including prescription and non-prescription drugs, herbal products, and health supplements.
