Warnings
Black Box Warnings
Effects of all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects
These symptoms may include asthenia, generalized muscle weakness, diplopia, blurred vision, 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 death have been reported
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 underlying conditions that would predispose them to these symptoms
In unapproved uses, including spasticity in children and adults, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and at lower doses
Contraindications
Hypersensitivity
Allergy to cow milk protein
Injection site infection
Cautions
Exercise caution when administering to patients with surgical alterations to facial anatomy, excessive weakness or atrophy in the target muscle(s), marked facial asymmetry, inflammation at the injection site(s), ptosis, excessive dermatochalasis, deep dermal scarring, thick sebaceous skin or the inability to substantially lessen glabellar lines by physically spreading them apart
Not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of abobotulinumtoxin cannot be compared to or converted into units of any other botulinum toxin products assessed with any other specific assay method
Toxin may spread - watch for dyspnea, dysphagia or speech impairment
Product contains albumin, a derivative of human blood; based on effective donor screening and product manufacturing processes; carries an extremely remote risk for transmission of viral diseases and variant Creutzfeldt-Jakob disease (vCJD); there is a theoretical risk for transmission of Creutzfeldt-Jakob disease (CJD), but if that risk actually exists, the risk of transmission would also be considered extremely remote; no cases of transmission of viral diseases, CJD, or vCJD have ever been identified for licensed albumin or albumin contained in other licensed products
Neutralizing antibody formation and loss of efficacy associated with higher doses or more frequent administration of the drug
Arrhythmia and myocardial infarction reported with use
Dysphagia reported with use for cervical dystonia; may persist for several weeks following administration and could cause the patient to require alternative feeding methods, including a feeding tube; smaller neck muscle mass, injections into the elevator scapulae or injections into the sternocleidomastoid muscle may increase risk of dysphagia; risk of aspiration may result from severe dysphagia when swallowing is already compromised; occurrence may be reduced by limiting the dose injected into sternocleidomastoid muscle
Use caution in patients with neuromuscular disease, including myasthenia gravis and Eaton-Lambert syndrome, and neuropathic disorders, such as, amyotrophic lateral sclerosis
Injection of the orbicularis muscle may reduce blinking and lead to corneal exposure and ulceration, when treating blepharospasm
Use caution when treating patients with preexisting respiratory disease; treatment of cervical dystonia, may weaken accessory muscles necessary to patients to maintain adequate ventilation; serious breathing difficulties, including respiratory failure reported
Dry eye has been reported in the treatment of glabellar lines; reduce tear production, reduced blinking, and corneal disorders, may occur with use of botulinum toxins; if symptoms of dry eye (eg, eye irritation, photophobia, visual changes) persist, consider referring patient to an ophthalmologist
Possibility of an immune reaction when injected intradermally is unknown; safety for the treatment of hyperhidrosis has not been established; approved only for IM injection
Exercise caution when administering to patients with surgical alterations to the facial anatomy, marked facial asymmetry, inflammation at the injection site(s), ptosis, excessive dermatochalasis, deep dermal scarring, thick sebaceous skin
Drug interaction overview
-
Aminoglycosides and other agents interfering with neuromuscular transmission
- Coadministration with aminoglycosides or other agents interfering with neuromuscular transmission (eg, curare-like agents) should only be used with caution because the effect of the botulinum toxin may be potentiated
- If coadministered, closely monitor patients
-
Anticholinergic drugs
- Use of anticholinergic drugs after administration may potentiate systemic anticholinergic effects such as blurred vision
-
Other botulinum neurotoxin products
- Effect of administering botulinum neurotoxin products, at the same time or within several months of each other is unknown
- Excessive weakness may be exacerbated by another administration of botulinum toxin prior to the resolution of the effects of a previously administered botulinum toxin
-
Muscle relaxants
- Excessive weakness may be exaggerated by administration of a muscle relaxant before or after botulinum toxin administration
Pregnancy & Lactation
Pregnancy
There are no adequate and well-controlled clinical studies in pregnant women
Use only during pregnancy if the potential benefit justifies the potential risk to the fetus
In rats, abobotulinumtoxinA produced adverse effects on mating behavior and fertility
Animal data
- AbobotulinumtoxinA produced embryofetal toxicity in relation to maternal toxicity when given to pregnant rats and rabbits at doses lower than or similar to the maximum recommended human dose (MRHD) of 1000 units on a body weight (units/kg) basis
Lactation
There are no data on the presence in human or animal milk, the effects on the breastfed infant, or the effects on milk production
Consider developmental and health benefits of breastfeeding along with the mother’s clinical need and any potential adverse effects on the breastfed infant or from the underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

BOTULINUM TOXIN - INJECTION
(BOT-ue-LYE-num)
WARNING: See also Uses section.This medication can spread to other parts of the body after your injection, causing serious (possibly fatal) side effects. These can occur hours or even weeks after the injection. However, the chances of such serious side effects occurring when this medication is used for migraines or skin conditions such as wrinkles, eye spasm, or excessive sweating are extremely unlikely.Children being treated for muscle stiffness/spasms have the greatest risk of these effects, as well as anyone that has certain medical conditions (see Precautions section). Discuss the risks and benefits of this medication with your doctor.Get medical help right away if any of these very serious side effects occur: chest pain, difficulty breathing, excessive muscle weakness, irregular heartbeat, severe difficulty swallowing or speaking, loss of bladder control.
USES: There are different types of botulinum toxin products (toxin A and B) with different uses (eye problems, muscle stiffness/spasms, migraines, cosmetic, overactive bladder). Different brands of this medication deliver different amounts of medication. Your doctor will choose the correct product for you.Botulinum toxin is used to treat certain eye disorders such as crossed eyes (strabismus) and uncontrolled blinking (blepharospasm), to treat muscle stiffness/spasms or movement disorders (such as cervical dystonia, torticollis), and to reduce the cosmetic appearance of wrinkles. It is also used to prevent headaches in people with very frequent migraines. Botulinum toxin relaxes muscle by blocking the release of a chemical called acetylcholine.Botulinum toxin is also used to treat overactive bladder by patients who do not respond to or who cannot tolerate the side effects of other medications. It helps to reduce leaking of urine, feeling of needing to urinate right away, and frequent trips to the bathroom.It is also used to treat severe underarm sweating and drooling/excess saliva. Botulinum toxin works by blocking the chemicals that turn on the sweat and salivary glands.Botulinum toxin is not a cure, and your symptoms will gradually return as the medication wears off.
