The trendy cosmetic treatment has, in fact, been used safely in medicine for over 40 years…
Many people know of Botox® only through stories of celebrities with smooth, almost doll-like complexions that seem to defy their age. Yet Botox® has been used in mainstream medicine for decades – and you may well need it yourself one day.
Botox® – What is it really?
Botox® is simply the brand name for a medicine derived from the same substance responsible for botulism – Botulinum Toxin. Although other manufacturers produce similar products, Botox® is so widely used that its name is often used interchangeably, even by clinicians.
Botulism – Isn’t that dangerous?
While botulism itself causes muscle paralysis, extremely small, controlled doses of Botulinum Toxin can safely relax muscles that are in spasm (painful, involuntary tightening). Because the dosage is tiny and injected precisely where it is needed, side effects are uncommon, usually mild, and limited to a small area. Typically, the effects begin to appear within 3 to 10 days and last for around 3 to 4 months.
Over 40 years ago, researchers began using minute doses to treat muscles that were permanently over-contracting. Around 20 years ago, the first medical application of Botulinum Toxin received approval, and it has since been licensed in the UK for the treatment of several medical conditions (reducing wrinkles does not count as a medical use!).
What does it treat?
Most medical uses of Botulinum Toxin relate to muscle overactivity. These include conditions such as cerebral palsy in children and uncontrolled blinking (blepharospasm). Other key uses in adults include:
• Cervical Dystonia – This painful spasm of the neck muscles affects more than 40,000 people in the UK. It twists the head to one side and makes normal posture difficult. Botulinum Toxin injections can ease the spasm, improve appearance, reduce pain, and make everyday activities more manageable.
• Arm Muscle Spasm After Stroke – Around one in three people who experience a stroke develop muscle spasticity. While sometimes mild, it can also cause significant pain and limit movement. Botulinum Toxin can help reduce both discomfort and stiffness.
• Chronic Migraine – This is the most recently approved medical use. It is reserved for people who experience migraine on at least half of the days in a month and only after several other treatments have failed.
• Excessive Sweating (Hyperhidrosis) – Although it may sound minor, it can be extremely distressing. Botulinum Toxin is one of several effective treatment options.
• Urinary Urgency – Administered under anaesthetic, Botulinum Toxin can selectively relax an overactive bladder muscle. This helps retrain bladder function and reduces reliance on long-term medication.
Is it for me?
Botulinum Toxin isn’t suitable for everyone and must be administered by a doctor who is properly trained in the field. If you think you may benefit from treatment, speak to your GP for further guidance.
