What You Need To Know About The Potential Side Effects Of Botox

During clinical research, the most common adverse reactions following Botox injection were headache, flu syndrome, respiratory infection, drooping eyelid and nausea.

Some of the less frequent adverse reactions were redness and swelling at the injection site, facial pain, tingling sensation and muscle weakness. Obviously we shouldn't be surprised at weakness of the injected muscles because this is what Botox is meant to do. However, occasionally local spreading can lead to weakness of the neighbouring muscles. The good news is that these side effects were largely temporary, but there is a chance that they may last longer than several months.

In real life setting, temporary ptosis (the medical term for eyelid drooping) happened in about 5 percent of the patients according to the literature. Other adverse reactions that have been found since Botox has gone on sale are blurred eyesight, tummy pain, decrease in hearing, diarrhoea, ear noise, fever, focal numbness, appetite loss, malaise, glaucoma, muscle pain, focal facial paralysis, erythema multiforme, itchiness, psoriasiform eruption, blockage of the retinal blood vessels, myasthaenia gravis and fainting.

It must be stressed that these reactions are volunteered in a non-controlled environment, so whether these can be directly linked to Botox remains unknown. Also, the incidence of these adverse reactions cannot be reliably predicted.

In very rare cases, there have been reports of spontaneous death, which can be accompanied by anaphylaxis, swallowing difficulty and/ or severe chest infection. Other rare serious adverse reactions are myocardial infarction, arrhythmia and/ or seizure.

Should you be deterred by this article, don't. The truth is, most people will never suffer from these serious side effects, and go on to improve their looks through Botox. To make things better, since Botox only linger in your system up to a maximum of six months, any adverse reactions will disappear eventually.
