What is oxybutynin?
The active component in oxybutynin tablets is oxybutynin hydrochloride. It is categorised as both an anticholinergic and antispasmodic medicine.
Anticholinergics block the action of the chemical acetylcholine. Acetylcholine is released by nerve endings that supply muscles and glands. The muscles are those that work involuntarily controlling the internal body organs, while secretory glands such as sweat glands are found throughout the body. Both ensure the normal functioning of the body. Acetylcholine attaches to specific acetylcholine receptors on muscle cells and glands thereby stimulating muscle cell activity and the secretion of glands. Anticholinergic drugs prevent acetylcholine from attaching to its receptors, inhibiting muscle and gland stimulation. Similarly, antispasmodics are anticholinergics, impeding the action of acetylcholine and preventing muscle and gland stimulation.
Oxybutynin works by blocking the action of acetylcholine. Oxybutynin inhibits gland stimulation including the sweat glands, resulting in a reduction in secretions such as in sweat production. Additionally, by relaxing the bladder muscles, it prevents abrupt muscle contractions or spasms, helping you to control the release of urine from your bladder.
How to use oxybutynin
Oxybutynin is available as a tablet, which can release the drug at a standard rate or over a prolonged period (slow release). Standard oxybutynin tablets are available in strengths of 2.5 mg, 3 mg, and 5 mg. Slow-release oxybutynin tablets contain 5 mg. All oxybutynin tablets are swallowed with a glass of water, with or without food. Slow-release oxybutynin tablets must be swallowed whole, not chewed, broken or crushed. Your doctor will prescribe the dose most appropriate for your symptoms and can change the dose according to your needs. Your doctor will tell you when to stop taking oxybutynin.
You must seek medical attention immediately if you take too many tablets, as this can cause side effects leading to unconsciousness. Take your forgotten tablet(s) as soon as you realise, unless you are due to take your next dose soon. In this case, skip the forgotten dose and take the scheduled next dose (never take two doses to account for a missed dose).
Who can use oxybutynin?
Oxybutynin can be used by adults, older people, and children aged 5 years or older. Speak to your doctor about your plans for having a baby or breastfeeding, or if you are or may be pregnant. Oxybutynin is not recommended during breastfeeding.

Your doctor will also want to know about all the medicines that you take or took recently, including both prescription and non-prescription medicines, as this may interfere with the way oxybutynin or the other treatments work.

This is the treatment I have found to be most effective for excess sweating. I still feel hot, but without the embarrassing sweating. Which has also reduced my anxiety.

Works very well - takes the edge off excessive sweating. Been using for a very long time with no side effects.

Lets say I noticed when I ran out that I could not cope outside and started sweating severely. I have had limited side effects but I suggest not to run out, otherwise this can cause headaches.
