What to do if you miss a dose of Caverject

Missing a dose of Caverject (Alprostadil) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Caverject is taken event-driven or daily at 10mcg, 20mcg, 40mcg. The wrong action — doubling up — is not recommended.

For daily Caverject

If Caverject is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Alprostadil, two doses should never be taken close together to "make up" for a miss.

For event-driven Caverject

If Caverject is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. Alprostadil binds prostaglandin E receptors on smooth muscle of the corpus cavernosum, triggering cAMP-mediated relaxation of cavernosal smooth muscle independent of the nitric oxide pathway used by P…

Frequently asked questions

Should I double the dose if I missed Caverject? ▾

No. Doubling doses of Caverject to compensate is not recommended at any 10mcg, 20mcg, 40mcg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.

How many missed doses are too many? ▾

Occasional missed doses of Caverject are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Erectile Dysfunction (ED), consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
