Botox is a drug which is used to treat muscle spasms and relax tense muscles. These days it is commonly called as onabotulinum toxin A, while previously it was named as Botulinum toxin A. it is really an effective and useful option for getting rid of wrinkles and lines on the body. However, like any other medicine it has few adverse or side effects. They are not compulsorily to come. Few individuals tolerate them well enough while few do not.
In discussion here we divide the side effects into common and uncommon ones as common side effects are those which are faced by most of the users. You should not be worried about their side effects because most of these side effects are not dangerous at all and they are gone even without using any medicine.
So the common but minor side effects of botox associated with cosmetic use or treatment of other medical conditions like torticollis, tic douloreux etc are:
- It results in drooping of eyelids because of excessive relaxation of the muscles holding the eyelids in position.
- Swallowing may become difficult, also known as dyspahgia by using botox in high doses especially while treating medical conditions.
- Nausea and if not controlled resultant vomiting is also another side effect of botox use.
- As it relaxes the muscles, so if it is used to treat the facial wrinkles, facial muscle weakness is the outcome, muscles which are paralysed are orbicularis oris, orbiculrais oculi etc.
- It may result in unusual pain in the face with no obvious reason and it is sometimes really unbearable.
- Heartburns, indigestion, gastroesophageal reflux are also likely to occur while using botox. They can be prevented by using some anti reflux or gastroprotective medicines.
- Elevated blood pressure known as hypertension and resultant headaches are also one of the common side effects of botulinum toxin use.
- Other minor side effects are like cough, flu like symptoms, toothaches, back pain, dizziness, local reaction to the injection site and backaches.
However, in some cases botulinum toxin may spread to other parts of the body where not required and thus may result in some serious side effects which may require intervention by a healthcare provider. This condition is known as botulism. One of the serious side effects is muscle weakness all over the body including respiratory muscles causing respiratory difficulty. Moreover diplopia or double vision, speech problems and severe swallowing problems may also ensue which required some immediate management. However, they are unusual.
