Claritin when planning pregnancy
For couples trying to conceive, every chronic medication deserves a careful pre-pregnancy review. Claritin (Loratadine) at 5mg, 10mg may need to be continued, switched, or stopped before conception, depending on the active ingredient Loratadine and the indication. The right answer is rarely the same for everyone and rarely "just stop the medication."
Pre-conception review of Claritin
According to the prescribing information for Loratadine, 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. Loratadine selectively blocks peripheral H1 histamine receptors, antagonising histamine effects during allergic reactions.
Effect on fertility itself
Some medications affect fertility directly — by altering ovulation, sperm parameters, hormonal balance or libido. Whether Claritin has any documented effect on fertility depends on Loratadine; the prescribing information notes any data. Anyone trying to conceive should discuss Claritin with the prescriber and a fertility specialist if conception is taking longer than expected.

Does Claritin affect male fertility? ▾
