Hydrea and Keppra drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Hydrea (hydroxyurea) and Keppra (levetiracetam). Common drug interactions include palmar-plantar erythrodysaesthesia syndrome among females and asthenia among males.

The phase IV clinical study analyzes what interactions people have when they take Hydrea and Keppra. It is created by eHealthMe based on reports of 45 people who take the same drugs from the FDA, and is updated regularly.

What is Hydrea?

Hydrea has active ingredients of hydroxyurea. It is often used in polycythemia vera. eHealthMe is studying from 9,083 Hydrea users. Check the latest studies of Hydrea.

What is Keppra?

Keppra has active ingredients of levetiracetam. It is often used in epilepsy. eHealthMe is studying from 73,504 Keppra users. Check the latest studies of Keppra.
