Penicillin and Lactulose drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Penicillin (penicillin g potassium) and Lactulose (lactulose). Common drug interactions include hypertension among females and alanine aminotransferase increased among males.

The phase IV clinical study analyzes what interactions people have when they take Penicillin and Lactulose. It is created by eHealthMe based on reports of 49 people who take the same drugs from the FDA, and is updated regularly.

What is Penicillin?

Penicillin has active ingredients of penicillin g potassium. It is often used in strep throat. eHealthMe is studying from 8,567 Penicillin users. Check the latest studies of Penicillin.

What is Lactulose?

Lactulose has active ingredients of lactulose. It is often used in constipation. eHealthMe is studying from 46,960 Lactulose users. Check the latest studies of Lactulose.
