I am concerned that not enough is known about this drug (It has only been approved for 2 years - Caution would dictate waiting until a drug has been on the scene for 5 years.
I would like to know any history that can be related concerning its use and possible side effects with the drug program I am on

I wanted to discuss the new medicine that I am taking with inspra. 18 years ago I was diognosed with bi-lateral arterial renal infarction. This was because I smoked and took rolaides regularly. The Dr. told me that I was overdoseing on both. Since then I have stopped smoking and I do not eat rolaides any more. I do take a water pill everyday and I take a potassium replacement. The amount I take is 8 mill. twice a day.
About 5weeks ago I had a heart attack which was mild and I had a stint put in and my doctor put me on Inspra. He said that my potasium level was low and this would be a good medicine to place me on. I read all the info that is given me on every med that I take. My Question is, will this take care of my problem takeing a water pill and is there any advise that I need to know regarding Inspra. I have side effects of all the meds that I take and I am conserned about what this med will have. Any information that you can give me will help. Thanks for your time and any help you can give me I will Appreciate it.

I am retired and on a very limited income $1500.00 pr month. Your Inspra 25 mg product costs me $123.25 per month.
I understand that you might have a hardship program that would provide me your product at no charge? Please consider.

Happy that Inspra is here.

I am a male who have been taking Spirolactone for over four years and it has caused gynomastica (enlarged breast in men) and other problems for me. According to my doctor, Inspra will work the same from the positive point of view , but without the negative "stuff" that I have had to deal with. I am happy that Inspra is here and I do hope it works as anticipated.
