The toxin itself is released from the bacterium as a single chain, then becomes activated when cleaved by its own proteases.[11] The active form consists of a two-chain protein composed of a 100-kDa heavy chain polypeptide joined via disulfide bond to a 50-kDa light chain polypeptide.[35] The heavy chain contains domains with several functions: it has the domain responsible for binding specifically to presynaptic nerve terminals, as well as the domain responsible for mediating translocation of the light chain into the cell cytoplasm as the vacuole acidifies.[1][35] The light chain is a zinc metalloprotease and is the active part of the toxin. It is translocated into the host cell cytoplasm where it cleaves the host protein SNAP-25, a member of the SNARE protein family which is responsible for fusion. The cleaved SNAP-25 is unable to mediate fusion of vesicles with the host cell membrane, thus preventing the release of the neurotransmitter acetylcholine from axon endings.[1] This blockage is slowly reversed as the toxin loses activity and the SNARE proteins are slowly regenerated by the affected cell.[1]
Simply put, "Baby Botox" uses a lower volume of Botox (a.k.a. botulinum toxin injections) than a traditional injection to smooth fine lines and wrinkles. "Instead of using 25 units in an area, you may use 10 units," Melissa Doft, a board-certified plastic surgeon in New York City, tells Allure. "I have many patients who ask for half the normal dose, as they do not want to look frozen but are tired of wrinkles in photos. First-time Botox patients are perfect for this."

In patients who are not catheterizing, post-void residual (PVR) urine volume should be assessed within 2 weeks post treatment and periodically as medically appropriate up to 12 weeks, particularly in patients with multiple sclerosis or diabetes mellitus. Depending on patient symptoms, institute catheterization if PVR urine volume exceeds 200 mL and continue until PVR falls below 200 mL. Instruct patients to contact their physician if they experience difficulty in voiding as catheterization may be required.
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.
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.

That’s enough to generate buzz on the patient forums like RealSelf among those who have tried it: “My neck is killing me” wrote one user;  I’ve got “Stiffness, pain in the neck, headache and can’t look down” reported another. Like anything, results vary widely. “I have since felt nauseous and dizzy on and off every day, as well as have blurry vision.


Botulinum toxin produced by Clostridium botulinum is the cause of botulism.[9] Humans most commonly ingest the toxin from eating improperly-canned foods in which C. botulinum has grown. However, the toxin can also be introduced through an infected wound. In infants, the bacteria can sometimes grow in the intestines and produce botulinum toxin within the intestine and can cause a condition known as floppy baby syndrome.[32] In all cases, the toxin can then spread, blocking nerves and muscle function. In severe cases, the toxin can block nerves controlling the respiratory system or heart, resulting in death.[1] Botulism can be difficult to diagnose, as it may appear similar to diseases such as Guillain–Barré syndrome, myasthenia gravis, and stroke. Other tests, such as brain scan and spinal fluid examination, may help to rule out other causes. If the symptoms of botulism are diagnosed early, various treatments can be administered. In an effort to remove contaminated food which remains in the gut, enemas or induced vomiting may be used.[33] For wound infections, infected material may be removed surgically.[33] Botulinum antitoxin is available and may be used to prevent the worsening of symptoms, though it will not reverse existing nerve damage. In severe cases, mechanical respiration may be used to support patients suffering from respiratory failure.[33] The nerve damage heals over time, generally over weeks to months.[4] With proper treatment, the case fatality rate for botulinum poisoning can be greatly reduced.[33]

* LS mean change, treatment difference and p-value are based on an analysis using an ANCOVA model with baseline weekly endpoint as covariate and treatment group, etiology at study entry (spinal cord injury or multiple sclerosis), concurrent anticholinergic therapy at screening, and investigator as factors. LOCF values were used to analyze the primary efficacy variable.

Temporary bruising is the most common side effect of Botox. Headaches, which resolve in 24-48 hours, can occur, but this is rare. A small percentage of patients may develop eyelid drooping. This usually resolves in three weeks. This usually happens when the Botox moves around so you shouldn't rub the treated area for 12 hours after injection or lay down for three to four hours.
On April 6, 2016, the company announced it would partner with Heptares Therapeutics in a deal valued up to $3.3 billion to collaborate on the development of a subtype-selective muscarinic agonists for Alzheimer's disease and other major neurological disorders.[21] On April 21, the company announced the acquisition of Topokine Therapeutics for at least $85 million, gaining the phase IIb/III compound XAF5 - a treatment for dermatochalasis.[22] On August 2, the company sold its generic drugs business to Teva Pharmaceutical Industries for $33.4 billion and 100.3 million shares of Teva.[23] On August 11, the company announced the acquisition of ForSight VISION5 for more than $95 million.[24] On September 6, the company acquired RetroSense Therapeutics for more than $60 million, gaining the positive photosensitivity gene therapy treatment, RST-001. RST-001 is to be used in retinas in which rod and cone photoreceptors have degenerated over time, causing in increase in the sensitivity of light hitting the retina.[25] On September 20, the company announced the acquisition of Tobira Therapeutics for $1.695 billion[26] and, a day later, the acquisition of Akarna Therapeutics for $50 million.[27] On October 3, the company sold Anda, its generic drug distribution business, to Teva for $500 million.[28] On October 25, the company acquired Vitae Pharmaceuticals, focused on dermatology treatments, for $639 million.[29] On October 27, the company announced it would acquire Motus Therapeutics, a developer of treatments for gastrointestinal disorders, for $200 million.[30] On November 22, 2016, the company acquired Chase Pharmaceuticals for an upfront payment of $125 million.[31]
Now, thanks in large part to off-label use, Botox--the wrinkle smoother that exploded as a cultural phenomenon and medical triumph--is increasingly being drafted for problems that go far beyond the cosmetic. The depression suffered by Rosenthal's patient is just one example on a list that includes everything from excessive sweating and neck spasms to leaky bladders, premature ejaculation, migraines, cold hands and even the dangerous cardiac condition of atrial fibrillation after heart surgery, among others. The range of conditions for which doctors are now using Botox is dizzying, reflecting the drug's unique characteristics as much as the drug industry's unique strategies for creating a blockbuster.
"The difference between using a cannula and a 'needle injection' technique is cannulas are a blunt tip needle that lets us place filler on a plane that allows it to last longer," explains Goodman. "They look better and preserve the 'untouched look' we're known for. Also, it's a more advanced technique that ensures the patient will not leave the office bruised."

Three percent of patients experienced eyelid drooping in the frown lines studies, one percent of patients experienced eyelid swelling in the crow's feet studies, and one percent of patients experienced brow drooping in the forehead lines studies. Other possible side effects include: dry mouth; discomfort or pain at the injection site; tiredness; headache; neck pain; eye problems: double vision, blurred vision, decreased eyesight and dry eyes; and allergic reactions. These are not all of the possible serious side effects of BOTOX® Cosmetic. Please see the Important Safety Information including Boxed Warning and Medication Guide and talk to your specialist.


BOTOX is administered about every three months, and must be injected at the site of each nerve trigger, relaxing the surrounding muscles so that they won’t compress the nerve and trigger a migraine. It is a potent drug, and we only recommend using it if other preventative treatment options haven’t helped you. It is generally only administered to patients who have at least 14 headaches a month, or don’t respond to other treatments.
BOTOX® treats the symptoms of severe underarm sweating when topical medicines do not work well enough in people 18 years and older. It is not known whether BOTOX® is safe or effective for severe sweating anywhere other than your armpits. BOTOX® treatments temporarily block the chemical signals from the nerves that stimulate the sweat glands, resulting in reduced sweating.
