Severe side effects are very rare but can happen if the botulinum toxin unexpectedly spreads throughout the body from the site of the shots. This can cause muscle weakness, hoarseness or trouble talking, trouble saying words clearly, loss of bladder control, trouble breathing, trouble swallowing, double vision, blurred vision and drooping eyelids. The breathing and swallowing problems can be life-threatening. If this happens, seek medical attention right away.
I increase the dose at each treatment cycle to 195 units. This is based on experience with patients with cervical dystonia, in whom higher doses result in a longer duration of effect. In addition, I transition to the next onabotulinumtoxinA treatment at 12 weeks by using occipital and trigeminal nerve blocks at 10 weeks. Most insurance companies will not cover onabotulinumtoxinA treatments earlier than 12 weeks, but in rare cases, 10-week cycles have been approved.
Preventative Botox has been getting lots of buzz. “It can potentially have a preventive effect on dynamic wrinkles, which are caused by underlying muscle movement,” Shah explains. “That being said, muscle movement is only one factor that contributes to the development of wrinkles, so Botox may not be completely preventive.” (Some other wrinkle causes: sun exposure, smoking, and diet.)
Children do very well after having this procedure in our clinic and are not upset when they leave. We rarely use sedation. We use distraction and a quick injection method instead. In rare cases, localization of a muscle may be needed using an electromyograph (EMG) machine or electric stimulator. If this is needed we will discuss this before scheduling the injections.
In 1820, Justinus Kerner, a small-town German medical officer and romantic poet, gave the first complete description of clinical botulism based on extensive clinical observations of so-called “sausage poisoning”. Following experiments on animals and on himself, he concluded that the toxin acts by interrupting signal transmission in the somatic and autonomic motor systems, without affecting sensory signals or mental functions. He observed that the toxin develops under anaerobic conditions, and can be lethal in minute doses. His prescience in suggesting that the toxin might be used therapeutically earned him recognition as the pioneer of modern botulinum toxin therapy.
For most of our guests, the effects of the treatment can last anywhere from 3-6 months. Many factors can influence how long the effects last. As the product wears off, muscle action returns gradually, & the previously treated lines & wrinkles may begin to reappear, and need to be treated again. With repeated treatment, the lines and wrinkles often appear less severe than before, as the muscles are being trained to relax.Some of these factors that may shorten or lengthen the effects include:
Postmarketing reports indicate that the effects of BOTOX® Cosmetic and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and spasticity and at lower doses.
Twenty two adult patients, enrolled in double-blind placebo controlled studies, received 400 Units or higher of BOTOX for treatment of upper limb spasticity. In addition, 44 adults received 400 Units of BOTOX or higher for four consecutive treatments over approximately one year for treatment of upper limb spasticity. The type and frequency of ad verse reactions observed in patients treated with 400 Units of BOTOX were similar to those reported in patients treated for upper limb spasticity with 360 Units of BOTOX.
Other potential adverse events that may occur with breast implant surgery include: asymmetry, breast pain, breast/skin sensation changes, capsular calcification, delayed wound healing, hematoma, hypertrophic scarring/scarring, implant extrusion, implant malposition, implant palpability/visibility, infection, nipple complications, redness, seroma, swelling, tissue/skin necrosis, wrinkling/rippling.
Unopened vials of BOTOX should be stored in a refrigerator (2° to 8°C) for up to 36 months. Do not use after the expiration d ate on the vial. Administer BOTOX within 24 hours of reconstitution; during this period reconstituted BOTOX should be stored in a refrigerator (2° to 8°C). Reconstituted BOTOX should be clear, colorless, and free of particulate matter.
Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.
