Allegra when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Allegra (Fexofenadine) at 30mg, 60mg, 120mg, 180mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Fexofenadine and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Allegra
According to the prescribing information for Fexofenadine, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some Allergy and Antihistamines medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Allegra has any documented effect on fertility depends on Fexofenadine; the prescribing information notes any data. Anyone trying to conceive should discuss Allegra with the prescriber and a fertility specialist if conception is taking longer than expected.

Does Allegra affect male fertility? ▾
