Years of experience has proven botox to be safe and effective. As with any procedure, there are certain complications that are possible. However, with a non-surgical treatment like botox, these are almost unheard of. But, it’s still important for you to do your own research before you making your decision.

Typically, the adverse events are related to the injection technique of the practitioner, rather than the neurotoxin itself. As such, they are preventable with thorough knowledge of muscle anatomy and adequate training technique.
Injection site pain, oedema, bruising are general adverse effects associated with the physical act of intramuscular injection itself. Local diffusion (spreading) of the product can lead to ptosis (hanging of the eyelid) that needs to be treated with eye drops to reverse the effect of the botox. Total reversal could take 3 weeks.
A totally “frozen look” is due to poor patient selection and incorrect injection technique. Headaches which can last for around 24 hours have been cited as a side effect of botox therapy, although it may only be due to the act of the injection itself. Interestingly, botox has been shown to be effective in the treatment of chronic headaches.
Contraindications to botox use are: neuromuscular medical conditions, pregnant or lactating women, inflammatory skin conditions at injection sites, allergy to human serum albumin. Additionally, patients on Disprin and Warfarin may experience excessive bruising.
