Clopidogrel and Tenormin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Clopidogrel (clopidogrel) and Tenormin (atenolol). Common drug interactions include seizure among females and gastrointestinal haemorrhage among males.

The phase IV clinical study analyzes what interactions people have when they take Clopidogrel and Tenormin. It is created by eHealthMe based on reports of 51 people who take the same drugs from the FDA, and is updated regularly.

What is Clopidogrel?

Clopidogrel has active ingredients of clopidogrel. It is often used in blood clots. eHealthMe is studying from 92,160 Clopidogrel users. Check the latest studies of Clopidogrel.

What is Tenormin?

Tenormin has active ingredients of atenolol. It is often used in high blood pressure. eHealthMe is studying from 20,474 Tenormin users. Check the latest studies of Tenormin.
