Itchy forehead after Botox. Could that be to do with the injections?

Good Morning, thank you for your question. You should know that itching it's not a common effect after botox injection. Some bruising and/or swelling on injection site can happen but is usually temporary. You should consider an allergic reaction to latex or other product if were used in your consult. 

Thank you for
your question cinzia. I am sorry to hear about your situation. Botox is
a purified protein used to address wrinkles associated with facial expression. With any injection there is a risk for redness and swelling. Itching is less common but can be possible for those with a latex allergy if latex gloves were used during the treatment. I recommend to my patients who experience pruritus (itching) to use over-the-counter strength hydrocortisone twice daily for a few days. If it persists, other treatments are available. Please consult with
a doctor for specific recommendations. Good luck!
