3.3 in not dangerously low but it certainly can cause symptoms. I've had low potassium around the same range and had symptoms. Not sure how much potassium you're taking viap ills, but if you're still that low my best recommendation is to drink V8 it's the highest potassium/ low sugar ratio drink I've been able to find. It has about 500mg of potassium per cup and only 8 grams of sugar. Add about 3 cups of V8 to on top of what ever your intake is at the moment and you'll be fine.

Sorry for the double post but I should have mentioned that low magnesium can contribute to low potassium so make sure you`re getting enough magnesium.

The normal range for potassium is 3.5 to 5.0, so you can see that your level is really not very low.  However, some people are more sensitive to this, and you do have symptoms that fit with low potassium.

At 3.3, you should not be in danger of anything truly bad, like a heart attack of any kind, but since your symptoms are very troubling to you, and your potassium is staying low in spite of supplements, you are entitled to call your doctor and ask for a further workup to determine what is going on.

There are medical conditions that should be investigated when the blood level of potassium refuses to come back up.  Do not panic, though, because it is usually very treatable.

When you say potassium pills, are they suplements or real pharmaceutical grade potassium medication ordered by your dr.?

Of course you should control all your electrolites periodically and be aware that some of the symptoms that you report seems to me more related to lack of magnesium.

Also be aware of interaction with other medicaments.

I agree with HesAPooka that V8 juice is a good source of potassium, but the sodium/potassium ratio is more important for many people than the absolute amount of postassium.  For that reason, perhaps either or both of you might want to consider using low-sodium V8, rather than the regular V8.  There is a difference in the taste, for obvious reasons, but the low-sodium V8 works better for me.  I was able to get used to the low-sodium taste very quickly.

im up to 2 potassium pills now my doc has me on i also take diamox due to my pseudotumor cerebri thats whats takeing my potassium away i dont see no inprovement yet im still haveing fast heartbeart the muscle cramps and now weakness in my chest i cant really leave my bed im so dizzy and almost falling

Some of your symptoms may be due to psuedotumor cerebri that is not yet under control.

As you may know,  Diamox itself--a well-studied drug for psuedotumor--can cause symptoms similar to those of low potassium.  

There are other treatments for pseudotumor, such as a surgically implanted shunt.  

In addition, for those who are overweight, losing that weight can apparently sometimes be curative.

Here is an article on pseudotumor cerebri:


i suggest you see your doctor again to tell him how bad you feel and to get more information on how to treat your problem more efficiently.
