What is a muscle relaxant?

The muscle relaxant is a non-invasive or non-surgical treatment that is mainly used to treat wrinkles but is highly effective for anti sweating treatments. It consists of botulinum toxin which is a neurotoxin and temporarily blocks the signalling from the nerve that stimulates the production of sweat. It is an effective treatment that has minimal side effects.

What can trigger excessive sweating?

Some factors such as an overheated body, feeling emotional, or a change in hormones may activate the nerves of the sweat gland. These nerves may overreact and lead to excessive sweating. For instance, if a situation can cause anxiety, then it can trigger excessive sweating.

Injectable muscle relaxant has multiple benefits including:

  • The anti-sweat treatment is effective and can reduce the production of sweat at the level of the underarms

How do muscle relaxants work?

Botulinum toxin is a neurotoxin that has the ability to temporarily block the signalling from the nerve or change the function of different neurotransmitters. Muscle relaxant injections help to block the nerve that tells the sweat gland to produce sweat. We can control excessive sweating by using these muscle relaxants.

Is injectable muscle relaxant effective?

The injectable muscle relaxants are very effective to treat excessive sweating. It is approved by U.S. Food and Drug Authority (FDA) to use injectable muscle relaxant for the treatment of excessive sweating at the level of the underarms.

The anti-sweat treatment with muscle relaxant

The muscle relaxant treatment for excessive sweating should be performed by a plastic surgeon. The procedure is simple and takes less than 10 minutes to perform the treatment. Typically, there is no need for local anaesthesia in the underarm area. If you feel discomfort, you can tell Dr Kernohan to use topical anaesthesia before inserting the needles. Dr Kernohan may inject neurotoxin with the help of fine needles.

You can receive multiple injections, so it typically forms a grid pattern on the surface of the treated area. You should be able to get back to the normal routine after the completion of treatment because this procedure has no downtime.
