My son playes baseball, and he gets bad leg cramps (charlie horses). Is it ok for him to have potassium pills or should I give him some else?

My son playes baseball, and he gets bad leg cramps (charlie horses). Is it ok for him to have potassium pills or should I give him some else?

Probably Not: A healthy 9 year old who eats a regular diet should not have issues with low potassium unless there is some underlying problem. Low magnesium can also cause leg cramps. Instead of giving potassium pills I would suggest just a regular children's multivitamin. If the problem does not resolve with this I would have his pediatrician check a complete metabolic panel to look for any abnormalities.

I supplement with 100 mg potassium daily-- too much? When I eliminate it I get leg cramps.

I supplement with 100 mg potassium daily-- too much? When I eliminate it I get leg cramps.

Not too much: Potassium is usually dispensed as potassium chloride or potassium citrate. 100 mg usually refers to the weight of the salt. Physicians usually put patients on 10 to 20 meq of potassium as a supplement if needed. 10 meq of potassium = 1, 080 mg of potassium citrate or 750 mg of potassium chloride.

Would a person taking statin drugs that gets leg cramps be helped by k tab potassium pills?

Would a person taking statin drugs that gets leg cramps be helped by k tab potassium pills?

No on 2 counts: Statins don't cause leg cramps and potassium doesn't cure them. Statins can cause generalized aching and reduction of dose is usually all that's required to correct that. Sometimes switching drugs is needed. Leg cramps are very common and generally related to overstretch and overuse. Stretching and warm-up exercises done daily helps most people.

I get leg cramps really bad. I have done everything they say to take magnesium and potassium but not together. They wake me up hurting. Suggestion?

Leg cramps: It may be time to see a neurologist, pmnr doctor, or pain specialists. Things to consider would include nerve irritation and/or a back problem. Your physicians may consider an EMG or a lumbar MRI based on your symptoms and physical exam. Hope you can get to the bottom of it and feel better.

Potassium levels a little low. My potassium levels were a little low, most likely due to water pills I take (triamterene) dr put me on potassium 10 meq once a day, been on them for a month now and still feeling crummy and getting leg cramps and soreness

Yes,: Yes, it is possible that potassium levels can continue to drop even though you are taking potassium pills. Rechecking the potassium would be reasonable. Also you may need a magnesium supplement for your cramping so ask your doctor about that. There are foods that can increase your potassium (bananas, melon, etc), so after your potassium is rechecked and if it is still low that is something to consider.

What is a good mg amount of a potassium supplement to add daily if my potassium is low after hospital blood work? I'm getting severe leg cramps.

Potassium: Potassium comes in 10 mEq tabs. The usual daily replacement dose is 20-40 mEq/day. Usually magnesium is also low and needs to be repleted, too. Talk to your doc about having it prescribed and also have your lytes, K, Mg, etc rechecked in couple of weeks.

Difficult problem: Your magnesium level should be checked. Trying over the counter magnesium is an option even if your level is normal, also although not well understood Benadryl (diphenhydramine) 25 mg (antihistamine) works great for night (nocturnal) leg cramps. Also if not contra indicated for you your md may also try Diltiazem a calcium channel blocker at night.

Check veins: Irritation of muscles due to overwork, swelling can result in cramping. Abnormalities in electrolytes like potassium, calcium can precipitate cramping, but venous insufficiency is a more common cause. Go to www.Phlebology.Org, and seek advice of a phlebologist in your area. For now try stretching exercises prior retiring in the evening.

What can I do for leg cramps?

Go see your doctor: Review your medications w/your doc after telling her/him what bothers you. Any diuretics (water pills)? These can upset your electrolye balance leading to cramps. We used to recommend quinine for leg cramps but it's not easily available, nor inexpensive these days. You could try drinking tonic water, perhaps. Stretching is always helpful. Make sure no swelling in affected leg.
