There are a number of medications available to help prevent excessive sweating which are usually recommended when topical treatments have been unsuccessful. These are generally used to treat underarm, chest, back, groin or head sweating. Some examples of which are given here, but other options are available and can be explored with your GP.

Aldioxa/chloroxylenol, available under the brand name Zeasorb®, can be purchased over the counter, without a prescription. It is a powder which relives sweating and helps to prevent infection.

Propantheline bromide belongs to the class of drugs called antimuscarinics and it works by blocking the nerve chemical messenger called acetycholine, preventing signals from reaching the sweat glands.

Beta Blockers can be prescribed for people who suffer anxiety which exasperates their sweating, and work by blocking adrenaline and nor-adrenaline.

It is important to remember that medications are not a cure. They work on a temporary basis and will not completely eradicate the issue. If the medication is stopped, the issue is likely to return.

Side effects of medications for excessive sweating may include dry mouth, extreme thirst, drowsiness, urinary retention, increased body temperature, constipation, blurred vision and difficulty swallowing.

Most medications must be prescribed by your GP but some are available over the counter.
