Hyperhidrosis has been estimated to affect between one and three in every 100 people which means there are likely to be hundreds of thousands of people living with it in the UK.

Most people suffering from hyperhidrosis will have tried commercial antiperspirants which are based on aluminium chloride or similar chemicals. The doctor will assess whether there might be an underlying cause, and may start treatment.

You will not be able to have Botox injections if you are pregnant, considering becoming pregnant, breast feeding. Also, if you suffer, or have been diagnosed with any muscular or heart problems you must not proceed with treatment. This will also apply if you are taking certain antibiotics or use any drugs as muscle relaxants, or if you have any bleeding disorder or are taking anticoagulant drugs.

Do I need to do anything before coming for the injections?

Please do not shave under your arms or use deodorant during the 24 hours prior to your appointment time. Please wear dark / black clothing as iodine solution is painted onto the skin, which will stain for a few days.

Will I need to take extra care after the treatment?

You can resume normal activity immediately after the treatment but please refrain from using deodorant for at least 2/3 days.

How long will the Botox work for?

Botox is not a permanent cure and some people may get greater benefit than others. In hyperhidrosis, Botox helps to stop or greatly reduce the symptoms. This will usually happen within two weeks of treatment and the effects may last between six and seven months. If you find that this treatment has helped you, it can be repeated, this will give you the greatest benefit.

What are the possible side effects?

Most common side effects are: sweating in sites other than armpits, swelling, stinging and pain in the injection site, headache and hot flushes.

Less common: nausea, itching, temporary muscle pain and weakness, joint stiffness, pain in armpits.
