Caverject Impulse 10 ug/.5mL (Alprostadil INJECTION, POWDER, LYOPHILIZED, FOR SOLUTION) 10 ug/.5mL

Caverject Impulse is a Prostaglandin E1 analog used to treat erectile dysfunction. It works by relaxing the smooth muscles in the penis and increasing blood flow to produce an erection.

• Erectile Dysfunction: Helps achieve and maintain an erection for sexual activity.
• Diagnostic Tool: Used as an adjunct to other diagnostic tests in the diagnosis of erectile dysfunction.
• Neurogenic Erectile Dysfunction: Effective in patients with spinal cord injuries or other neurogenic causes of erectile dysfunction.

• Alprostadil, the active ingredient in Caverject Impulse, works as a direct vasodilator. It relaxes penile smooth muscle via cAMP-mediated pathways, increasing blood flow to the penis and producing an erection. This mechanism helps to achieve and maintain an erection suitable for sexual activity.

Caverject Impulse may cause side effects, ranging from common to serious or rare. It is important to be aware of these potential effects before using the medication.

Common Side Effects

• Penile pain: The most frequently reported side effect, occurring in about 6.1% of users.
• Prolonged erection: An erection lasting longer than 4 hours, which can be painful and requires immediate medical attention.
• Priapism: A prolonged erection that lasts more than 4 hours and can cause tissue damage if not treated promptly.
• Bruising or bleeding at the injection site: Minor bleeding or bruising may occur where the injection is administered.
• Dizziness or lightheadedness: Some users may experience temporary dizziness after administration.
• Headache: A common side effect that may occur after using the medication.

Serious or Rare Side Effects

• Fibrosis: Prolonged use can lead to scarring or fibrosis of the penile tissue.
• Hypotension: A significant drop in blood pressure, which can be dangerous for individuals with cardiovascular conditions.
• Allergic reactions: Rare but possible, including rash, itching, or swelling.

Caverject Impulse should be used with caution and under the guidance of a healthcare provider. Certain precautions and warnings should be observed to ensure safe and effective use.

• Dosage Adjustment: Start with the lowest effective dose to minimize the risk of prolonged erection or priapism.

Major Interactions (Avoid)

• Other vasodilators: Concurrent use with other vasodilators can increase the risk of hypotension.
• Anticoagulants: May increase the risk of bleeding at the injection site.
• Antiplatelet drugs: Can enhance the risk of bruising or bleeding.

Moderate Interactions (Monitor Closely)

• Alpha-blockers: May enhance the hypotensive effects of alprostadil.
• Nitrates: Can increase the risk of hypotension when used together.
• Other erectile dysfunction medications: Concurrent use may increase the risk of prolonged erection or priapism.
