When it comes to ED, CAVERJECT IMPULSE is designed to help.



    CAVERJECT IMPULSE is a medicine that is used to treat impotence (erectile dysfunction) in adult men.


    Finding your dose

    The first injection of CAVERJECT IMPULSE should be administered under the supervision of a healthcare provider in his or her office. Self-administration of CAVERJECT IMPULSE requires proper training. During this training, an individual dose of CAVERJECT IMPULSE will be established by a doctor.


    What to expect

    After injection, it takes as little as 5 to 20 minutes to develop an erection that should last no longer than 1 hour and be sufficient for sexual intercourse.


    Single use

    CAVERJECT IMPULSE is for one use only and should be thrown away after a single use.
    This means that the prescribed dose can be set each time and confirmed through the "dial-a-dose" window.

Important Safety Information

Do not use CAVERJECT CAVERJECT® (alprostadil for injection) if you have certain conditions that might cause long-lasting erections (lasting more than 4 hours). Long-lasting erections may cause penis damage. These conditions include:

  • sickle cell anemia or trait
  • leukemia
  • tumor of the bone marrow (multiple myeloma)

Do not use CAVERJECT if you

  • have a penile implant
  • have an abnormally formed penis
  • have other penis problems
  • were told by your doctor not to have sex

Women and children should not use CAVERJECT.

Some men who use CAVERJECT may get erections that last more than 4 hours. These can cause serious and permanent damage. Call your doctor or seek professional help immediately if you still have an erection 4 hours after injection.

The most common side effect of CAVERJECT is mild to moderate pain after injection. About one-third of patients report this effect.

You may get a small amount of bleeding at the injection site. This is more likely if you have a medical condition or are taking a medicine that interferes with blood clotting.

CAVERJECT does not protect you from sexually transmitted diseases (STDs), such as HIV (the virus that causes AIDS). Small amounts of bleeding at the injection site can increase the risk of passing diseases carried by the blood, such as HIV.

The use of other medical treatments for impotence (erectile dysfunction) in combination with CAVERJECT is not recommended. Discuss any concerns you may have about combination treatment with your doctor.

Call your doctor if you notice any redness, lumps, swelling, tenderness, or curving of the erect penis. Also, tell your doctor about any penis pain you did not have before or other penis problems you have.

There is a possibility of needle breakage with use of CAVERJECT IMPULSE. To best avoid breaking the needle, you should pay careful attention to your doctor's instructions and try to handle the device properly. If the needle breaks during injection and you are able to see and grasp the broken end, you should remove it and contact your doctor. If you cannot see or cannot grasp the broken end, you should promptly contact your doctor.

Patients should always ask their doctors for medical advice about adverse events.

You may report an adverse event related to Pfizer products by calling 1-800-438-1985 (US only). If you prefer, you may contact the U.S. Food and Drug Administration (FDA) directly. The FDA has established a reporting service known as MedWatch where health care professionals and consumers can report serious problems they suspect may be associated with the drugs and medical devices they prescribe, dispense, or use. Visit MedWatch or call 1-800-FDA-1088.
