There are about 4 different kinds/classes of Diuretics.

I have found that I experience severe cramps when I take Thiazide and Thiazide-like Diuretics.(one)

I now take a Loop Diuretic(two) which solved my problem. One of my other Blood Pressure Meds causes me to retain Potassium and even though the Loop Diuretic may deplete some Potassium I maintain stable levels.

The other classes are (three) Potassium-sparing Diuretics and (four) Combination Diuretics.

Ask your Neuro which kind would be best for you then talk to your GP.
