Two hundred thirty-one patients enrolled in a double-blind placebo controlled study (Study 8) received 300 Units to 400 Units of BOTOX, and were compared with 233 patients who received placebo. The data reflect the patients whose test results were considered positive for neutralizing activity to BOTOX in a mouse protection assay or negative based on a screening ELISA assay or mouse protection assay. Botulinum toxin is produced by a specific type of bacteria. Dysphagia and symptomatic general weakness may be attributable to an extension of the pharmacology of BOTOX resulting from the spread of the toxin outside the injected muscles [see WARNINGS AND PRECAUTIONS]. Double vision, drooping or swollen eyelid, eye irritation, dry eyes, tearing, reduced blinking, and increased sensitivity to light may also occur. However, only small, weaker doses of botulinum toxin are used to reduce facial wrinkles.

[1] Clinicians have used this neurotoxin in practice since late 1970. The following adverse reactions to BOTOX (onabotulinumtoxinA) for injection are discussed in greater detail in other sections of the labeling: Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. 1996-2022 RxList, Inc. All rights reserved. [18][12], These treatments are in addition to supportive therapy. The table below presents the most frequently reported adverse reactions during the 12 weeks following intradetrusor administration of BOTOX 200 Units. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Local weakness of the injected muscle(s) represents the expected pharmacological action of botulinum toxin. Botulinum toxin A inhibits the release of acetylcholine, relieving muscle contraction and spasm associated with many conditions, such as incontinence and dystonia. In a double-blind, placebo-controlled trial (Study 1), 78 patients were treated with 3 Units/kg of BOTOX, and 77 patients received 6 Units/kg to a maximum dose of 200 Units of BOTOX, and were compared to 79 patients who received placebo [see Clinical Studies]. .

Check with your doctor or nurse immediately if any of the following side effects occur while taking onabotulinumtoxinA: More common Difficulty with swallowing Rare Difficulty with breathing or speaking muscle weakness More commonfor blepharospasm Dryness of the eyes inability to close the eyelids completely More commonfor upper limb spasticity Several countries developed botulinum toxin as aerosol weapons in the past. Animal models suggest that inhaling 0.7-0.9 g of aerosolized botulinum toxin would be enough to kill a standard weight person (70 kg or 154 lbs). This mechanism allows for antidystonic effects not only caused by target muscle paresis. There are a few drugs that facilitate acetylcholine release, including tetraethylammonium and 4-aminopyridine. Botulism causes flaccid paralysis, which begins in the muscles of the head and neck and progresses to the muscles of the trunk and extremities. Eur J Neurol. A release of aerosolized botulinum toxin would likely result in an outbreak of acute flaccid paralysis (sudden, profound muscle weakness) among persons in the same geographic area who have had no obvious common dietary exposure. Reduction of formalin-induced pain suggests direct analgesic BT effects possibly mediated by blockade of substance P, glutamate and calcitonin gene-related peptide. In patients with reduced lung function treated for upper limb spasticity, upper respiratory tract infections were reported more frequently in treated patients compared with placebo (up to 11% vs 6%). No change was observed in the overall safety profile with repeat dosing during an open-label, uncontrolled extension trial. Symptoms of a serious allergic reaction may include: itching/swelling (especially of the face/tongue/throat), rash, severe dizziness, trouble breathing. BT affects the spinal stretch reflex by blockade of intrafusal muscle fibres with consecutive reduction of Ia/II afferent signals and muscle tone without affecting muscle strength (reflex inhibition).
