Caverject injections are typically self-administered by the patient after proper training from a healthcare professional.

It is crucial to discuss with your healthcare provider before combining different treatments to ensure safety and efficacy.

Alprostadil and Caverject should not be used by individuals with certain medical conditions, such as those with a history of priapism, penile fibrosis, or conditions that increase the risk of priapism, such as sickle cell anemia or leukemia. Additionally, caution should be exercised in individuals taking blood-thinning medications or those with certain cardiovascular conditions. Always consult with your doctor to determine if Alprostadil or Caverject is suitable for you.
