Dealing with sweating
The treatment you have to stop your sweating depends on what is causing it. If you have an infection, antibiotics will treat the infection and stop the sweating. If your sweating is due to cancer then treating the cancer can stop it.
If you are sweating because treatment has changed your hormone levels, it may settle down after a few weeks or months, once your body is used to the treatment.
Talk to your doctor or nurse about your sweats. There are different treatments you can try.
Some drugs help to reduce the number of hot flushes and sweats you have and can make them less severe. They include drugs such as:
clonidine (a blood pressure and migraine medicine) can help women with breast cancer
anti depressants such as paroxetine or venlafexine
gabapentin (an epilepsy drug) can help women with breast cancer
medroxyprogesterone or cyproterone acetate (hormones) can help men with prostate cancer
cimetidine (a drug to reduce stomach acid) can reduce sweating caused by morphine
All these treatments have side effects. It is important to talk to your doctor about them before you start and discuss how long you should take them. We need more research to find the best way to reduce hot flushes and sweats.
People sometimes use complementary medicines to help control sweating. Research has had varying results so far.

avoid alcohol and caffeine as this dilates the blood vessels in the skin, increasing sweating
avoid spicy foods and eating large meals late at night
keep your room at a cool, comfortable temperature
have a fan nearby at night or use a handheld fan
wear layers of clothes so you can easily take off or put on a layer to adjust your temperature
use light cotton bedclothes so you can take some off if you get hot
if you are sweating a lot at night, lie on a soft towel to soak up moisture and keep your sheets dry
drink at least 2.5 to 3 litres (preferably water) a day as you can lose a lot of fluid in sweat
have a lukewarm shower or bath before bed
