Is it safe to take Loratadine with Pregnancy?
Loratadine is generally the antihistamine recommended first for pregnant women who need one, based on extensive reassuring data including large registry studies. An early suggestion of a link with hypospadias was investigated and not confirmed in bigger analyses. As with any medicine in pregnancy, use the lowest effective dose and confirm regular use with your midwife or pharmacist — but this is among the best-supported allergy options available.
How do Loratadine and Pregnancy interact?
Loratadine is a non-sedating peripheral H1 antagonist. Swedish and Danish registry data covering thousands of pregnancies show malformation rates equivalent to background. Its metabolite desloratadine shows the same profile.
Data sourced from the US Food and Drug Administration (FDA) drug label database: OpenFDA loratadine label; UKTIS review — no confirmed hypospadias association.

Frequently Asked Questions
Is loratadine safe in pregnancy?
Yes — it's the usual first-choice antihistamine in pregnancy, backed by large reassuring studies.
Didn't loratadine get linked to a birth defect?

Loratadine isn't controlling my hay fever — what next?
Try cetirizine instead, add a pregnancy-suitable steroid nasal spray, and use saline rinses. Ask your pharmacist to check any product before you buy.
Can I take loratadine every day of pregnancy?
Daily use through hay fever season is reasonable when needed — mention it at your antenatal appointments so it's on your record.
