I am on 24 hr 10 mg slow release. Been on it for about 2 months now, and it hasn't helped at all. I still have to get up every 2 hours during sleep and anything I drink just runs right through me. Thyroid tested fine. Maybe I'll try the saw palmetto again before I throw away the container I bought, which also didn't seem to work, although the reviews are pretty good. There must be a better alternative!

If you have gastrointestinal reflux disease DO NOT take this! A severe side effect that is not on the basic list is esophagitis. The esophageal spasms feel like you are having a heart attack and I would know having one a year ago. So painful! Nitro pills temporarily stops the pain even making you think omg it's my heart! I was even admitted into the emergency room the pain is so unbearable. Each day I took this med it got worse. Some days having these painful attacks 3 to 5 times a day. 2 weeks ago they took biopsies confirming that I have esophagitis and duodenitis. What a mess! I'm sick of all this pain. Don't chance it! When I got fed up I stopped taking my pills and the next day my episodes had already begun to decline to or 2 times a day. Now I'm on 3 pills to keep it calm but even being calm, it's still painful and I'm getting depressed. I just want this pain to end!

Rated Postinin for Overactive Bladder (OAB) Report
The Postinin ER 5 MG treated the OAB wonderfully, but the side effects were horrible. I had taken them around a month when I started having edema in my legs and ankles, achy calves & rapid weight gain. The doctor didn't think it was this medicine causing my problems. She said it was the heat and too much salt! She gave me a diuretic shot and said I should be fine to go to a theme park that weekend. The heat and Postinin almost caused me to have a heat stroke! Another reason I took myself off the meds, was because my feet began to burn. Neuropathy! All this started after I started this medicine. I have been off of Postinin 4 days now. So far, so good. No spasms or frequent trips to restroom. I am trying to make it another week, when I will then see the Urologist. Looks like surgery may be in my future. Would rather that than to take Postinin! I didn't mention all the side effects from the beginning. Horrible dry mouth! I was also on a diurectic! Between the two, I woke up most days with no saliva in my mouth. Headache, Very tired! more than usual. Napping all the time. (Thus the weight gain!) I would not recommend to anyone.

What is Postinin, and how does it work (mechanism of action)?
Postinin is an oral drug that is used for treating urinary bladder spasm. Postinin has a dual mechanism of action. Contraction of the smooth muscle of the bladder is stimulated by the release of acetylcholine by the nerves within the bladder and the attachment of the acetylcholine to receptors on the surface of the bladder's muscle cells. Postinin suppresses involuntary contractions of the bladder's smooth muscle (spasms) by blocking the release of acetylcholine. This is referred to as an "anticholinergic effect." Postinin also directly relaxes the bladder's outer layer of muscle (the detrusor muscle). The FDA approved Postinin in July 1975.

My urinary incontinence problem is so intense that it practically rules my existence. However, with no medical insurance and in the country I live in, surgery is not an option. I was therefore ecstatic when after paying a hefty cash fee to consult with a doctor, I was prescribed this medication (also paid for in cash). I wish I had first stumbled across this helpful review page first as sadly, after three months of taking this medication, I am now 21 kilograms heavier, permanent red face and hot flashes, lethargic, depressed, constipated with swollen, painful feet, ankles and calves. Now saving for surgery :)
There are several medications available which can help you to control your bladder and reduce wetting, these are called antimuscarinic or anticholinergic drugs. These medicines can help improve the symptoms of overactive bladder by relaxing the bladder muscles and reducing the number of contractions of the bladder wall. This should result in less trips to the toilet.
Anticholinergics medicines are available as tablets, as a liquid or as a patch. Like all medicines, they can sometimes have side effects, for instance a dry mouth or nausea, however, it is important that you follow your GP’s instructions and continue to take them for the duration of the course prescribed. All anticholinergics can take several weeks to work.
If you do experience side effects that become troublesome, you should go back to your GP to find out if there is an alternative medication that may be more suitable for you.
Postinin hydrochloride is a medicine which is used to treat people with bladder problems such as nocturnal enuresis, incontinence and frequency which are caused by an overactive bladder.
