Like all medicines, Botulinum Toxin can have side effects, although not everybody gets them. In general, side effects occur within the first few days following injection. They usually last only for a short time, but they may last for several months and in rare cases, longer. These adverse reactions may be related to treatment, injection technique or both.
Diffusion of botulinum toxin into nearby muscles is possible when high doses are injected, particularly in the neck area.
As expected for any injection procedure, pain/burning/stinging, swelling and/or bruising may be associated with the injection. Speak to your doctor if you are worried about this.
Adverse reactions possibly related to the spread of toxin distant from the site of administration have been reported very rarely with botulinum toxin (e.g. muscle weakness, constipation, difficulty in swallowing, food or liquid accidentally going into the lungs which in some cases may lead to pneumonia). Injection of Botulinum Toxin is not recommended in patients with a history of dysphagia (difficulty to swallow) and impaired swallowing.
The chance of having a side effect is described by the following categories:
- Common - More than 1 out of 100 persons and less than 1 out of 10 persons.
- Uncommon - More than 1 out of 1,000 persons and less than 1 out of 100 persons.

The aesthetic effects of Botulinum Toxin last for an average of 3-4 months but will vary depending on the condition of the skin, area treated, amount of product injected, injection technique and lifestyle factors such as sun exposure and smoking. (Please note: Although rare, some clients do not respond to Botulinum Toxin and therefore results may be minimal.)
After treatment, please avoid extreme facial expressions, alcohol consumption and applying make up for 12 hours. Please avoid extreme sun exposure, UV light, freezing temperatures and saunas for 2 weeks after treatment.
