Botox treatment is safe only if its use is limited as per the recommended dosage. Botox is the untainted or purified form of a strong chemical called botulinum toxin. This chemical is injected underneath the skin to paralyze the muscles underneath the face to smoothen and soften the fine lines and wrinkles. Unfortunately, there are numerous health related hazards if this drug is used for a long term. First and foremost, over-dosage or wrong dosage of this powerful drug can paralyze the nearby muscles of the intended area. This can cause inactivity of those muscles for a temporary period. Such a condition may make the eyelids droopy as well as trigger paralysis of other facial organs. In adverse reaction towards the induction of Botox, patients can experience pain, redness / rashes at the injected spot and a short-lived weakness of certain facial muscles. Further, bruising at the site of the injection is one of most common side effects of this non-surgical cosmetic treatment. Other potential side effects include headaches, nausea, flu-like symptoms and much more. In rare cases, the drug used in Botox injection can react with other medications already being used by the patient for the treatment of certain medical conditions.
