Does Claritin-D Cause Insomnia?
Claritin-D® (loratadine and pseudoephedrine sulfate), like all medications, can cause side effects. Insomnia is one of the most common side effects of Claritin-D. In clinical studies, up to 16 percent of people taking Claritin-D 12 Hour tablets experienced insomnia, compared to just 3 percent of people taking a placebo (a “sugar pill” with no active ingredient). However, insomnia was less common in people taking Claritin-D 24 Hour tablets (which are taken just once a day), occurring in only 5 percent of people.
