Knowing The Possible Adverse Reactions To Botox
| by Dr Vincent T | August 01, 2007
Before deciding on Botox to smooth your wrinkles, your doctor should let you know about some of the possible adverse events that could take place. Because your consultation time with the doctor may be limited, this article outlines a broad overview of the side effects that may not have been mentioned.
During scientific research, the most common side effects following injection of Botox were headache, nausea, flu-like symptoms, respiratory infection, and drooping eyelid.
Some of the less frequent side effects included redness and swelling at the injection site, facial pain, tingling sensation and muscular weakness. Naturally we shouldn't be surprised at weakness of the injected muscles because this is what Botox is meant to do. Having said that, occasionally spread of the toxin can cause weakness of the neighbouring muscles. Fortunately these side effects were largely temporary, but there is a chance that they may last longer than several months.
In real life setting, temporary eyelid drooping occurred in approximately five percent of the patients in literature reviews. Other side effects which have been reported since Botox has gone on the market are visual blurring, tummy pain, decrease in hearing, loose stool, noise in the ear, fever, localised parasthesia, appetite loss, feeling weak, glaucoma, muscular pain, localised facial paralysis, erythema multiforme, pruritus, psoriasis-like rash, blockage of the retinal blood vessels, myasthaenia gravis and fainting.
It must be emphasised that these side effects are volunteered in a non-controlled environment, so whether these can be directly linked to Botox remains unclear. Furthermore, the incidence of these events cannot be accurately predicted.
In very rare cases, there have been anecdotes of spontaneous death, which can be associated with anaphylaxis, dysphagia and/ or serious pneumonia. Other almost unheard of severe adverse events are myocardial infarction, heart rhythm disturbance and/ or epilepsy.
Should you be deterred by this piece, don't. The truth is, most people will never suffer from these severe side effects, and continue to reap the benefits of Botox. In any case, since Botox only stay in your system for between 4 to 6 months, any side effects will disappear after this time period.
