Second-generation H1 antihistamine
Cetirizine when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Cetirizine (Cetirizine) at 5mg, 10mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Cetirizine and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Cetirizine
According to the prescribing information for Cetirizine, the pre-conception decision balances the risk of the medication during pregnancy against the consequences of leaving the underlying condition untreated. Some Second-generation H1 antihistamine medications are continued safely through pregnancy; others are switched to safer alternatives before conception or in early pregnancy. Cetirizine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released by mast cells during allergic responses.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Cetirizine has any documented effect on fertility depends on Cetirizine; the prescribing information notes any data. Anyone trying to conceive should discuss Cetirizine with the prescriber and a fertility specialist if conception is taking longer than expected.
