What are the Side Effects
Botox has been used safely in ophthalmology for over 10 years, and in wrinkle therapy for over 6 years.
Botox side effects are relatively uncommon. The longest any Botox side effect can last is a maximum of 6 months. This is because Botox treatments are temporary. Anyone with a neuromuscular disorder should first consult their physician before undergoing a Botox injection.
The most common side effects include bruising at the site of the injection and headache. Less frequently occurring side effects (less than 3%) include face pain, erythema at the site of the injection, and temporary eyelid droop. These less likely side effects are related to the injection itself, and usually subside within 1 week.
