Dual 5α-reductase inhibitor (type 1 and type 2)
What to do if you miss a dose of Dutasteride
Missing a dose of Dutasteride (Dutasteride) 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 Dutasteride is taken event-driven or daily at 0.5mg. The wrong action — doubling up — is not recommended.
For daily Dutasteride
If Dutasteride 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 Dutasteride, two doses should never be taken close together to "make up" for a miss.
For event-driven Dutasteride
If Dutasteride 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. Dutasteride irreversibly inhibits both isoenzymes of 5α-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT).
Frequently asked questions
Should I double the dose if I missed Dutasteride? ▾
No. Doubling doses of Dutasteride to compensate is not recommended at any 0.5mg 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 Dutasteride are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Dual 5α-reductase inhibitor (type 1 and type 2), consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
