Hydroxyurea and Timolol drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Hydroxyurea (hydroxyurea) and Timolol (timolol). Common drug interactions include blood cholesterol increased among females and dehydration among males.

The phase IV clinical study analyzes what interactions people have when they take Hydroxyurea and Timolol. It is created by eHealthMe based on reports of 25 people who take the same drugs from the FDA, and is updated regularly.

What is Hydroxyurea?

Hydroxyurea has active ingredients of hydroxyurea. It is often used in polycythemia vera. eHealthMe is studying from 17,240 Hydroxyurea users. Check the latest studies of Hydroxyurea.

What is Timolol?

Timolol has active ingredients of timolol. It is often used in glaucoma. eHealthMe is studying from 9,142 Timolol users. Check the latest studies of Timolol.

How the study uses the data?

The study uses data from the FDA. It is based on hydroxyurea and timolol (the active ingredients of Hydroxyurea and Timolol, respectively), and Hydroxyurea and Timolol (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.

How to use the study?

DO NOT STOP MEDICATIONS without first consulting your doctor. If there are any serious or long term adverse effects discovered in the study, discuss the study with your doctor to ensure that proper medication management will be in place if applicable.
