I'm currently 15 weeks pregnant. I took 4 pills Diclectin per day from weeks 8-12, then 3 pills/day weeks 13 and 14 to control nausea and vomiting. Two days ago I stopped Diclectin completely. My nausea is mostly gone - at this point I rather the low level of nausea than the side effects I experienced on diclectin. I found that the Diclectin reduced my allergy symptoms. Since I stopped taking it, my nose my allergies are vey bad - runny nose, itchy eyes with tears, sneezing...it is very unpleasant. Is this because I stopped taking Diclectin? How long will this rebound effect last?
The reason your allergies were reduced while taking the Diclectin, is because one of the active ingredients, (doxylamine) is an older sedating antihistamine which is also effective for nausea and vomiting. It is difficult to say if this is a rebound effect or whether your allergies are worse because you are not taking the antihistamine anymore. Consequently, it is impossible to say how long these effects will last.
