Amoxicillin side effects by duration, gender and age - a phase IV clinical study of FDA data
Summary:
Side effects are reported by people who take Amoxicillin. Common side effects include drug hypersensitivity among females and renal failure among males.
The phase IV clinical study is created by eHealthMe based on 74,618 reports from the FDA, and is updated regularly. You can use the study as a second opinion to make health care decisions.
With medical big data and AI algorithms, eHealthMe enables everyone to run phase IV clinical trial to detect adverse drug outcomes and monitor effectiveness. Our original studies have been referenced on 600+ peer-reviewed medical publications including The Lancet, Mayo Clinic Proceedings, and Nature. Most recently, phase IV clinial trails for COVID 19 vaccines have been added, check here.
74,618 people who take Amoxicillin and have side effects are studied.
What is Amoxicillin?
Amoxicillin has active ingredients of amoxicillin. It is often used in infection. eHealthMe is studying from 77,807 Amoxicillin users for its effectiveness, alternative drugs and more.
Number of Amoxicillin reports submitted per year:

Do you take Amoxicillin?
Personalize this study to your gender and ageHow to use the study?
You can discuss the study with your doctor, to ensure that all drug risks and benefits are fully discussed and understood.
How the study uses the data?
The study is based on amoxicillin (the active ingredients of Amoxicillin) and Amoxicillin (the brand name). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered.
