K-Dur is an oral supplement (pill) made up of a mineral called potassium chloride. We carry the generic alternative of this medication in 20 MEQ (1500mg)!

K-Dur is used to treat and prevent potassium levels in the blood from becoming too low. This condition is known as hypokalemia and can be a result of a variety of conditions such as vomiting a lot, having diarrhea, having poorly working kidneys or adrenal glands, or urinating a lot. Potassium is an important part of muscle contraction regulation (moving muscles), healthy nerve function, and fluid balance regulation. Potassium also plays a part in affecting the cells in your heart and keeping your blood pressure from getting too high. K-Dur doesn’t only help to keep all these body functions working and potential risks from occurring, but may also help to relieve symptoms of weakness, fatigue, muscle cramps, twitching, constipation, and abnormal heart rhythms (arrhythmia) by treating and preventing this condition.

K-Dur is effective in treating and preventing hypokalemia because the active ingredient in K-Dur is potassium chloride, and is a direct substitute for the potassium that missing or misused that causes the deficiency (hypokalemia).

Only take this medication the way that your doctor has directed you too. Taking the incorrect dose can lead to unwanted side effects, ineffectiveness, or adverse interactions.

Take K-Dur with a full glass of water and with a meal or directly after a meal. Avoid chewing, sucking, or crushing this tablet as doing so may cause irritation.

Ensure you are taking the necessary tests required throughout this treatment such as blood tests.

Store K-Dur at room temperature and protect against moisture and heat.

Can’t swallow pills?
