Caverject is the brand name for the medication alprostadil. It is a prescription medication that is primarily used to treat erectile dysfunction (ED) in men. Here are some key points about Caverject injections:

1. Indications: Caverject is used to treat erectile dysfunction, a condition where a man has difficulty achieving or maintaining an erection sufficient for sexual activity.
2. Mechanism of Action: Caverject contains alprostadil, which is a synthetic form of prostaglandin E1. It works by relaxing and dilating the blood vessels in the penis, which increases blood flow to the area and helps facilitate an erection.
3. Administration: Caverject is available as an injection, and it is administered directly into the shaft of the penis. The injection is typically given shortly before sexual activity.
4. Onset of Action: Caverject works relatively quickly, often within 5 to 20 minutes after the injection.
5. Dosage: The dosage of Caverject is determined by a healthcare provider based on the individual patient’s condition and response to the medication.
6. Side Effects: Common side effects of Caverject can include pain at the injection site, penile bruising, and an ache in the penis. Priapism, a prolonged and painful erection lasting more than four hours, is a rare but serious side effect that requires immediate medical attention.
7. Precautions: Caverject may not be suitable for individuals with certain medical conditions, especially those at risk of priapism, or those taking specific medications. It’s essential to discuss any existing health conditions and medications with the healthcare provider.
8. Patient Education: Patients should receive education on how to properly administer Caverject, potential side effects, and the importance of reporting any new or worsening symptoms to their healthcare provider.
9. Duration of Treatment: Caverject is used as needed, shortly before sexual activity. It does not need to be taken on a daily basis.
   1. Alternative Treatments: Caverject is one of several options available for treating erectile dysfunction, and the choice of treatment depends on the patient’s preferences and medical advice.
