Dimetapp and Intracranial aneurysm - a phase IV clinical study of FDA data

Summary:

Intracranial aneurysm is reported as a side effect among people who take Dimetapp (brompheniramine maleate; phenylpropanolamine hydrochloride), especially for people who are female, 40-49 old, have been taking the drug for < 1 month also take Contac, and have Nasopharyngitis.

The phase IV clinical study analyzes which people have Intracranial aneurysm when taking Dimetapp. It is created by eHealthMe based on reports of 4,625 people who have side effects when taking Dimetapp from the FDA, and is updated regularly.
