During scientific trials, the most frequent side effects after injection of Botox were discovered to be headache, nausea, flu syndrome, respiratory infection, and drooping eyelid. Some less frequent side effects included injection site redness and swelling, facial pain, mild numbness and muscle weakness. Naturally we should expect weakness of muscles that are injected because this is what Botox is meant to do. However, sometimes spread of the toxin can lead to weakness of the neighbouring muscles. Fortunately these adverse events were generally temporary, but there is a chance that they may last longer. In real life setting, transient ptosis (the medical term for eyelid drooping) were reported in approximately 5 percent of patients in literature reviews. Other side effects which have been found since Botox has gone on sale are visual blurring, tummy pain, temporary hearing loss, loose stool, tinnitus, fever, localised parasthesia, appetite loss, malaise, glaucoma, muscle pain, localised facial paralysis, erythema multiforme, pruritus, psoriasis-like rash, blockage of the retinal blood vessels, myasthaenia gravis and syncope. It must be noted that these side effects are reported voluntarily outwith a clinical trial, so whether these can be directly attributed to Botox remains unclear. Also, the frequency of these events could not be precisely predicted. In very rare cases, there have been reports of spontaneous death, which may be associated with anaphylaxis, difficulty in swallowing and/ or severe chest infection. Other almost unheard of serious adverse reactions include myocardial infarction, arrhythmia and/ or seizure. Should you be frightened by this article, don’t. The fact is, more than 99% of people will never suffer from these serious adverse reactions, and continue to reap the benefits of Botox. Even better, since Botox only linger in your system up to a maximum of six months, any side effects should subside after this time period.
