Question 1

How often can I safely use Caverject injections?

Accepted Answer

Clinical guidelines strongly advise using Caverject no more than 3 times per week, leaving at least 24 hours of rest between each individual injection. Overuse significantly increases the risk of localized tissue scarring (penile fibrosis) or prolonged painful erections.

Question 2

What are the available Alprostadil alternative brands in Pakistan?

Accepted Answer

The pioneer, globally recognized brand available via import is Caverject by Pfizer. Other generic equivalents or alternative brands that contain Alprostadil include Edex (injections) and MUSE (intraurethral suppositories), though injectable configurations remain the most effective option.

Question 3

How should Pfizer Caverject 20 mcg be stored?

Accepted Answer

Unreconstituted (dry powder) vials should be kept below 25°C. Once you mix the Alprostadil powder with the bacteriostatic water, the solution should ideally be used immediately. Any remaining reconstituted solution must be stored between 2°C to 25°C and discarded after 24 hours. Do not freeze.

Question 4

Why does the price of Caverject 20 mcg vary in Pakistan?

Accepted Answer

Since Caverject is directly imported from the UK/Europe, its local price fluctuates in accordance with currency exchange rates, import duties, and strict temperature-controlled international logistics fees. All final pricing is finalized during your order confirmation call.

Question 5

Can my partner use Caverject if she is pregnant?

Accepted Answer

No, Caverject is not intended for female use. If your partner is pregnant or attempting to conceive, you must use a condom during intercourse. The added Prostaglandin E1 in the semen can absorb into the vaginal wall and potentially stimulate uterine contractions or cause preterm labor risk.

Question 6

How fast does Caverject 20 mcg work and how long does it last?

Accepted Answer

Typically, an intracavernosal injection of Alprostadil produces a stable erection within 5 to 20 minutes post-administration. The duration of the erection is dose-dependent but should ideally last between 30 to 60 minutes. If an erection persists past 4 hours, seek immediate medical attention.
