I am nine weeks pregnant and nauseous all the time. I'm considering diclectin but I recently heard of someone who used it and who's child developed many allergies. Have there been any studies that investigated links between this antihistamine-containing drug and allergy development in children?
We are not aware of any studies that examined this particular outcome, nor does there appear to be any evidence after thousands of women have used this medication in the past 40 years, that there is an increased risk for allergies in their children. Keep in mind that there are many reasons for developing allergies. Based on the evidence to date, it is unlikely that using Diclectin during pregnancy had anything to do with her child developing allergies.
