Loss of potassium symptoms and conditions

I have been on Flomax less than a week. Already I am seeing signs of mental confusion, being drowsy to the point of almost falling asleep at inopportune times, muscle cramps, and a dull ache in the area of the prostate.

Flow was good prior to starting Flomax. It has improved slightly but so has a sense of urgency. It seems to be acting a bit like a diuretic in that I am going a lot more frequently and with high volume and good pressure.

Diuretics can cause a loss of potassium, which can result in severe muscle cramps or spasm. I have had a charley horse in the calf, a foot that cramped up when I stood on it, and a tightening of the abdomen such that I could see a lump in one area. One must wonder if these are related.

The precautions include watching for heard palpitations. The heart is a muscle, isn't it? I would not want that muscle cramping up.

Perhaps the doctor thinks it advisable to attain perfection in urinary performance. But perhaps it is better to go through life with a slight problem that will likely not change, and also without irritating a gland that is prone to cancer. In reading the postings here it would seem that this medical perfection comes at a great cost.
