- Nitrates and Nitroglycerin: These medications, often used to treat angina and other heart conditions, can significantly lower blood pressure when used with Caverject.
5. Alpha-Blockers:

FAQs
Is using Caverject 10mcg/ml Dual Chamber injection painful?
Using Caverject 10mcg can cause some discomfort or pain at the injection site for some men. This is a common side effect and can vary in intensity from mild to moderate. The pain is typically brief and may decrease with regular use as you become more accustomed to the injection process. If you experience significant pain or persistent discomfort, it is important to discuss this with your healthcare provider, as they may adjust your dosage or injection technique to improve your experience.
How does Caverject 10mcg/ml Dual Chamber injection work?
Caverject 10mcg/ml works by using a medication called alprostadil, which is a synthetic version of a naturally occurring substance called prostaglandin E1. Alprostadil helps to relax the smooth muscle and dilate the blood vessels in the penis. This process increases blood flow to the penis, leading to an erection.
Here's how it works in detail:
- Injection: Caverject is injected directly into the corpus cavernosum, which is one of the two cylindrical chambers in the penis that fill with blood to create an erection.
- Relaxation of Smooth Muscle: Alprostadil relaxes the smooth muscle tissue in the corpus cavernosum.
- Dilation of Blood Vessels: The relaxation of smooth muscle tissue causes the blood vessels to dilate, allowing more blood to flow into the penis.
- Increased Blood Flow: The increased blood flow fills the corpus cavernosum, leading to an erection.
Caverject is typically effective within 5 to 20 minutes after injection, and the erection can last for about 30 to 60 minutes. It is important to follow the prescribed dosage and instructions provided by your healthcare provider to ensure safe and effective use of the medication.
What is the difference between the Caverject injection and the Caverject Dual Chamber injection?
Caverject injections and Caverject Dual Chamber injections are both used for treating erectile dysfunction, but they differ in their preparation and convenience. Standard Caverject injections require manual mixing of a powder and a solution using separate vials and syringes, which can be time-consuming and requires careful handling. In contrast, Caverject Dual Chamber injections streamline this process by combining the powder and solution within a single syringe. This dual-chamber system simplifies preparation, as it only requires mixing by twisting the plunger rod, eliminating the need for separate vials and reducing the risk of preparation errors. This makes Caverject Dual Chamber a more user-friendly and convenient option for patients.
