Mild pain, swelling, and bruising are common after Botox injections. Even the smallest needle can cause bruising or swelling, with a recent study showing that 9.2% of 218 patients experienced flu-like symptoms. Headaches can be easily treated with an over-the-counter (OTC) medication, such as acetaminophen. Other side effects may include swelling of the lips, eyelids, hands, or feet; swelling of the mouth, tongue, or throat; and flu-like symptoms.
To minimize the risk of side effects, it is important to work with a licensed medical professional. Working with someone who is not licensed can significantly increase the risk of side effects. After the procedure, it is important to take care of yourself to enjoy the full effects of your Botox experience. The use of anticholinergic drugs following administration of BOTOX may potentiate systemic anticholinergic effects.
These side effects don't always occur, and if they do, they usually resolve on their own within a few days. If you're thinking of using Botox to treat your condition, talk to your doctor about possible side effects you may have. The formation of neutralizing antibodies against Botulinum toxin type A may reduce the effectiveness of BOTOX treatment by inactivating the biological activity of the toxin. The toxic effects of Botox can sometimes spread from the area where the injections* are given, leading to a condition called botulism.
In studies, Botox side effects in children with blepharospasm or strabismus were similar to those seen in adults who used Botox for these conditions. People with neuromuscular disorders such as amyloid lateral sclerosis (ALS), Lambert-Eaton myasthenic syndrome, or myasthenia gravis may be at increased risk of certain side effects with Botox. However, side effects may indicate an allergic reaction and could be a reason for you to seek immediate help.
