Slow-k and Codeine drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Slow-k (potassium chloride) and Codeine (codeine sulfate). Common drug interactions include nausea among females and tachycardia among males.
The phase IV clinical study analyzes what interactions people have when they take Slow-k and Codeine. It is created by eHealthMe based on reports of 26 people who take the same drugs from the FDA, and is updated regularly.
What is Slow-k?
Slow-k has active ingredients of potassium chloride. It is often used in hypokalemia. eHealthMe is studying from 3,683 Slow-k users. Check the latest studies of Slow-k.
What is Codeine?
Codeine has active ingredients of codeine sulfate. It is often used in pain. eHealthMe is studying from 42,342 Codeine users. Check the latest studies of Codeine.
26 people who take Slow-k and Codeine together, and have interactions are studied.
