Dealing with sweating

Ways to reduce 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.

Hot flushes and sweats

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.

Things you can do to reduce sweating

  • 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

Skin problems with cancer

Cancer and cancer treatment can cause skin problems. But skin problems can be treated, and there are ways you can manage them at home.

Cancer and its treatment can affect the skin in different ways, causing problems such as itching, sweating or pressure sores (sore skin).

About the skin and cancer

Cancer and its treatment can damage the skin cells and stop them from working properly. Knowing more about how the skin works and what may affect it can help you care for it better.
