dizziness and Diaretic

  Is it possible for someone to be on too much Demedex?  I find that I am getting more and more dizzines.  I don't seem to be retaining any fluid and I wonder if is possible to get dizzy from that.  Could I drying out too much?  I am also on K-Dur.  How about that drug,  could that cause a problem with the dizzines?.  I really notice it when I am in bright lights  On my forhead between my eyes actually hurts when the dizziness comes..  Any help on this would be appreciated.

Dear Marlene,
YES, it is possible to be on too much Demedex, or too much of any kind of water pill.  The dizziness could be from too little total water (drying out as you say)and salt in the body which leads to lowered blood pressure which leads to dizziness.
YOU need to talk with your doctor about this as soon as possible, and keep in mind that it is not neccesarily th demedex, but that it is never detrimental to hold a water pill like demedex for a day or two so long as you do not get shortness of breath.
THE K-Dur is a potassium  replacement pill that you take along with the demedex since any water pill, while getting rid of extra water in your body,  will also waste potassium.  SO, if you hold the demedex for any reason, you should also hold off on the potassium(k-dur).
I Think it would be best for you to go to an emergency room to have your blood pressure and potassium checked, unless you are able to see your doctor very soon because you do not know for sure what is causing the dizziness, and the ER can help sort it all out, if not make sure that there is nothing life threatening.
Your head hurting that you speak of usually means that your blood pressure is too low for you to be standing, regardless you should at least sit down if not lie down when you get dizzi.  Also important when  on any type of blood pressure or water pill is that you not stand up too quickly, do it slowly so that the blood pressure can adjust.
IF YOU ARE EVER DIZZY WHILE LYING DOWN, CALL 911 FOR AN ambulance.
