Claritin and Dimetapp drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Claritin (loratadine) and Dimetapp (brompheniramine maleate; phenylpropanolamine hydrochloride). Common drug interactions include early satiety among females and lung infiltration among males.

The phase IV clinical study analyzes what interactions people have when they take Claritin and Dimetapp. It is created by eHealthMe based on reports of 53 people who take the same drugs from the FDA, and is updated regularly.
