Co-administration of BOTOX® or other agents interfering with neuromuscular transmission (eg, aminoglycosides, curare-like compounds) should only be performed with caution as the effect of the toxin may be potentiated. Use of anticholinergic drugs after administration of BOTOX® may potentiate systemic anticholinergic effects. The effect of administering different botulinum neurotoxin products at the same time or within several months of each other is unknown. Excessive neuromuscular weakness may be exacerbated by administration of another botulinum toxin prior to the resolution of the effects of a previously administered botulinum toxin. Excessive weakness may also be exaggerated by administration of a muscle relaxant before or after administration of BOTOX®.

If you find that your Botox wears off really fast, speak to the person who gave you the injections to find out why (i.e. if the Botox was too diluted, not enough was injected, the Botox was old, your anatomy requires a different technique, you might be resistant to Botox, etc). A reputable doctor will work with you to figure out how to make the Botox treatments worth your time and money. Keep in mind that for some people, Botox takes time to kick in - approximately 1-2 days to be noticeable and 1-2 weeks to peak.
Richard Clark, a plastic surgeon from Sacramento (CA), was the first to document a cosmetic use for botulinum toxin.[51] He treated forehead asymmetry caused by left sided forehead nerve paralysis that occurred during a cosmetic facelift. Since the injured nerve could possibly regenerate by 24 months, a two-year waiting period was necessary before definitive surgical treatment could be done. Clark realized that botulinum toxin, which had been previously used only for cross eyed babies and facial tics, could also be injected to smooth the wrinkles of the right forehead to match her paralyzed left. He received FDA approval for this cosmetic application of the toxin and successfully treated the person and published the case study in 1989.[51]

Patients with compromised respiratory status treated with BOTOX for spasticity should be monitored closely. In a double-blind, placebo-controlled, parallel group study in patients treated for upper limb spasticity with stable reduced pulmonary function (defined as FEV1 40-80% of predicted value and FEV1/FVC ≤0.75), the event rate in change of Forced Vital Capacity (FVC) ≥15% or ≥20% was generally greater in patients treated with BOTOX than in patients treated with placebo (see Table 5).
Before I could try Botox, my health insurance — Cigna — required me to try and fail at least two other meds. I tried tricyclic antidepressants, which made me groggy and turned my brain into molasses, and beta blockers, a class of drugs used for high blood pressure and heart problems. (All treatments to prevent migraines are borrowed from other conditions, except a new class of drugs that was just approved by the Food and Drug Administration.) The beta blockers worked for a few months: they slightly reduced the number of migraines and made the headaches more bearable. But late last year, the migraines became chronic again — I had more than 15 in a month. That’s when my neurologist said: “I think it’s time to try Botox.”
“I see a lot of patients who come in from sun damage, or who have creases in their foreheads, more lines around the sides of their mouths, crow's feet, and wrinkles on the side of their nose,” Shah says. “At this age, a dermatologist can inject Botox in the right places to help train a person’s face to no longer fall into that habit, which can help decrease the odds that they’ll develop permanent wrinkles in those spots later on.”
Launched in 2002, Practical Neurology is a publication uniquely dedicated to presenting current approaches to patient management, synthesis of emerging research and data, and analysis of industry news with a goal to facilitate practical application and improved clinical practice for all neurologists. Our straightforward articles give neurologists tools they can immediately put into practice.
In a double-blind, placebo-controlled, parallel group study in adult patients with detrusor overactivity associated with a neurologic condition and restrictive lung disease of neuromuscular etiology [defined as FVC 50-80% of predicted value in patients with spinal cord injury between C5 and C8, or MS] the event rate in change of Forced Vital Capacity ≥15% or ≥20% was generally greater in patients treated with BOTOX than in patients treated with placebo (see Table 6).
It is not known whether BOTOX® is safe or effective to treat increased stiffness in upper limb muscles other than those in the elbow, wrist, fingers, and thumb, or in lower limb muscles other than those in the ankle and toes. BOTOX® has not been shown to help people perform task-specific functions with upper limbs or increase movement in joints that are permanently fixed in position by stiff muscles. BOTOX® is not meant to replace existing physical therapy or other rehabilitation that may have been prescribed.
