Second-generation H1 antihistamine
What to do if you miss a dose of Fexofenadine
Missing a dose of Fexofenadine (Fexofenadine) 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 Fexofenadine is taken event-driven or daily at 30mg, 60mg, 120mg, 180mg. The wrong action — doubling up — is not recommended.
For daily Fexofenadine
If Fexofenadine 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 Fexofenadine, two doses should never be taken close together to "make up" for a miss.
For event-driven Fexofenadine
If Fexofenadine 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. Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle.
Frequently asked questions
Should I double the dose if I missed Fexofenadine? ▾
No. Doubling doses of Fexofenadine to compensate is not recommended at any 30mg, 60mg, 120mg, 180mg 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 Fexofenadine are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Second-generation H1 antihistamine, consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
