The potency Units of BOTOX® Cosmetic are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX® Cosmetic cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method.
SkinMedica® TOTAL DEFENSE + REPAIR Broad Spectrum/PA++++ Sunscreens (SPF 34, SPF 34 Tinted, and SPF 50+) and Essential Defense Broad Spectrum/PA++++ Sunscreens (Everyday Clear SPF 47, Mineral Shield Tinted SPF 32, and Mineral Shield SPF 35) are over-the-counter drug products that are formulated and marketed pursuant to the FDA's governing regulations set forth at 21 CFR § 352.
Botox is administered by injection and dosing depends on the condition that it is used for. Administration of botulinum toxin with other agents (for example, aminoglycosides, curare) that affect neuromuscular function may increase the effect of botulinum toxin. There are no adequate studies of Botox in pregnant women and it has not been evaluated in nursing mothers.
Now Allergan hopes to replicate the findings on a larger scale, and the company is currently running its own Phase 2 clinical trial. If its results are in line with Rosenthal and Finzi's, it would be huge, paving the way for Botox to obtain official approval for the drug as a depression treatment. That wouldn't change anything for doctors, of course--they can already prescribe it off-label, and some do, with great results--but it would allow Allergan to begin marketing Botox for depression, a change that could dramatically increase its adoption and sales.

Though botulinum toxin is available under different names, Botox is the only one that is FDA-approved for migraine prevention. To be considered for Botox, patients must have migraines 15 days or more per month, which is considered chronic daily migraine. About 4 million Americans have such migraines, according to the Migraine Research Foundation. Also, patients must have tried and failed on at least 2 other medications first.
Still, there have been enough concerns that the FDA instituted a REMS (Risk Evaluation and Mitigation Strategy) requirement for all botulinum toxin preparations that specifically addresses the issues of distant spread of the toxin and the risk of problems, leading to death, from swallowing or breathing issues in certain patients who may be susceptible after botulinum toxin treatment. All products, including Dysport, Myobloc, Xeomin, and Botox, are monitored via this strategy. This is specifically aimed at a certain population of patients receiving more than the usual doses of botulinum toxin and not aimed at the casual user of Botox, per se.
Some doctors, however, say their experience with their own patients indicates Botox — which was approved by the FDA in 2010 to treat migraines — is quite effective for this purpose. Lawrence Newman, MD, a neurologist and director of the headache division at NYU Langone Medical Center in New York City, says many of his patients have experienced a significant decline in the number of headaches per month after receiving Botox. In many cases, he says, it has cut down that number by 50% and frequently more than that.
Safety and effectiveness of BOTOX® have not been established for the treatment of other upper or lower limb muscle groups or for the treatment of spasticity in pediatric patients under age 18 years. BOTOX® has not been shown to improve upper extremity functional abilities, or range of motion at a joint affected by a fixed contracture. Treatment with BOTOX® is not intended to substitute for usual standard of care rehabilitation regimens.
Over time, the muscles above and between the eyebrows repeatedly contract and tighten, causing wrinkles. Botox Cosmetic works beneath the skin’s surface and targets the underlying muscle activity that causes frown lines and crow’s feet to form over time. Normally when we squint, frown, or make other facial expressions, our nerves release a neurotransmitter chemical, known as acetylcholine. This neurotransmitter binds to receptors within the muscle to make it contract. Wrinkle relaxers like Botox and DYSPORT® work by binding to the acetylcholine receptors, and blocking the signal from the nerve to the muscles.
Think about it this way: people make facial expressions every single day, whether it's expressing an emotion (i.e. smiling) or simply out of habit (i.e. raising your brows). Making facial expressions causes temporary dynamic lines to show up in your face. These lines go away when your face returns to rest. However, as you continue to make facial expressions, day after day and year after year, and as your skin ages, these lines start to get etched in your skin. That's when frown lines get progressively deeper for people who frown all the time. Or when crow's feet stay put even after you stop smiling or squinting. Eventually, what once were dynamic wrinkles become wrinkles that are just there, even when you don't make any facial expressions.
After Hoffman’s husband was diagnosed with Parkinson’s at 55, his health insurance decided to stop paying for the drug he had taken successfully unless he tried cheaper alternatives. She appealed on behalf of her husband and was eventually able to get approval for the drug, which would have cost them $8,000 a year otherwise. “I felt terrible and I had to fight and it took a long time,” Hoffman tells The Verge. “It caused a lot of anxiety and a lot of these patients don’t have a law professor wife to fight for them.”
On average, each BOTOX treatment requires 32 injections, though individual patients may require fewer or more. You’ll receive injections every twelve weeks, and each session only takes a few minutes. BOTOX begins to work as soon as it’s injected, and you should see full results within a week of your first injections. Most patients who benefit from BOTOX treatments receive five rounds of injections over 15 months. BOTOX is injected using a very fine needle. Most patients describe it as feeling like a tiny pinprick.
Step therapy is largely unregulated both at the state and federal level, though individual states have started to pass legislation to limit step therapy and protect patients: 19 US states, including California, Mississippi, and Illinois, have laws that require insurance companies to grant certain exemptions or to review appeals from doctors within 72 hours so patients can get a waiver. But even then, getting a waiver isn’t always easy.
In double-blind, placebo-controlled chronic migraine efficacy trials (Study 1 and Study 2), the discontinuation rate was 12% in the BOTOX treated group and 10% in the placebo-treated group. Discontinuations due to an adverse event were 4% in the BOTOX group and 1% in the placebo group. The most frequent adverse events leading to discontinuation in the BOTOX group were neck pain, headache, worsening migraine, muscular weakness and eyelid ptosis.
This imbalance can affect a joint in varied ways such as at the ankle with foot position (always points toes or up on toes when walking) or at the wrist with hand position (hand in flexion with problems grasping). After a contracture occurs (not able to bring the joint through its full range of motion, even with forceful / prolonged stretching) it can be hard to re-establish full range of motion at that joint without surgery.
