BOTOX or Botulinum toxin is a neurotoxin that causes denervation by inhibiting the calcium-dependent acetylcholine release in the presynaptic neurons. It is used to treat the following conditions:
-
Treatment of patients with axillary sweating also called axillary hyperhidrosis in adults that do not respond to topical therapy.
- Therapy with BOTOX should be initiated only when secondary causes like hyperthyroidism have been ruled out..
- Other than in the axillary region, treatment for hyperhidrosis may have negative side effects like weakness.
-
Treatment for patients 16 years of age or older with cervical dystonia.
-
For the prevention of persistent migraines that last longer than four hours per day for at least 15 days each month.
-
For the treatment of adult lower limb spasticity.
-
For the treatment of overactive bladder and urge incontinence in patients who have a poor or inadequate response to anticholinergic medicines.
-
For the treatment of Strabismus and blepharospasm associated with dystonia including benign blepharospasm in patients older than 12 years of age.
-
For the treatment of Upper limb spasticity.
-
For the treatment of Urinary incontinence due to detrusor overactivity in patients with neurologic conditions like multiple sclerosis and spinal cord injury.
-
Patients with children who have a dynamic equinus foot deformity have cerebral palsy.
-
Off-Label Uses of BOTOX in Adults include:

Warnings & Precautions
- Allergic reactions:
- There might be dyspnea, urticaria, soft tissue edoema, anaphylactic responses, and serum sickness.
- Antibody formation:
- Repeated and higher doses result in loss of efficacy due to antibody formation.
- Autonomic dysreflexia:
- After receiving a BOTOX injection intradetrusor, individuals with spinal cord injuries may have dysautonomia.
- Patients may develop resting tachycardia, fluctuating Blood Pressure readings, sweating, and may at times present with hypertensive crisis.
- Cardiovascular events:
- Patients with risk factors for cardiovascular diseases and those with preexisting heart disease may develop cardiac arrhythmias and myocardial infarction.
- Dysphagia:
- Patients with smaller neck muscles, injections into the levator scapulae, and those with bilateral injections are at risk of dysphagia.
- Dysphagia may be severe enough to require alternative feeding methods and may put the patients at risk of aspiration.
- Hematologic:
- Patients with a bleeding disorder and those on anticoagulants should use the drug with caution.
- Ophthalmic effects:
- When the orbicularis oculi muscle is injected, patients may have dry eyes, discomfort, photophobia, ocular pain, and altered vision.
- Respiratory effects:
- Upper respiratory tract infections like bronchitis can occur in patients undergoing treatment for upper or lower limb spasticity.
- Systemic toxicity: [US Boxed Warning]:
- Dysphagia and life-threatening respiratory failure may occur as a result of the systemic spread of the drug.
- In the hours or weeks following the injections, patients may also have diplopia, impaired vision, ptosis, asthenia, dysarthria, dysphonia, widespread muscular weakness, and incontinence.
- Urinary retention:
- Urinary retention can occur in patients receiving treatment for an overactive detrusor or an overactive bladder.
- Treatment should be offered only if the patient is willing for post-treatment catheterization.
- Urinary tract infections:
- An increase in the incidence of UTIs has been reported with its use, following intradetrusor administration.
- Patients who have had 2 or more episodes of UTIs in the past 6 months and diabetic patients are especially at risk.
- Episodic migraines:
- Efficacy of treatment in patients with less than 14 headaches per month has not been established.
- Neuromuscular disease:
- Patients with neuromuscular diseases such myasthenia gravis, Lambert-Eaton myasthenic syndrome, and motor neuron disease may experience a worsening of their symptoms.
- Ocular diseases:
- Exposure of the cornea When treating blepharospasm, decreased blinking may result in persistent corneal epithelial defects and ulceration.
- When treating strabismus, needle penetration into the orbit might cause retrobulbar haemorrhage.
- Glaucoma patients should use the medication with care.
- Respiratory disease:
- Patients who already have a respiratory condition should use the medication extremely cautiously since it may deteriorate the supporting muscles for breathing.
Monitor:
- Detrusor overactivity:
- two weeks after therapy, and then at regular intervals for up to twelve weeks, measure the volume of postvoid residual (PVR) urine.
- When the PVR urine volume is greater than 200 mL, catheterization should start and continue until the PVR is less than 200 mL.
How to administer BOTOX (ona botulinum toxin A)?
-
Administration of intradetrusor for the treatment of neurologic condition-related bladder dysfunction, including hyperactive detrusors and overactive bladder:
- Prophylactic antibiotic therapy (other than aminoglycosides) is advised to be given one to three days prior to, the day of, and for one to three days following BOTOX administration.
- Antiplatelet medication should be ceased for at least three days prior to its administration.
- In order to prepare the bladder for a local anaesthetic injection prior to therapy, the bladder must first be drained and irrigated with normal saline.
- Saline should be injected into the bladder to improve vision (avoid overdistention).
- Prime the syringe with roughly 1 mL of reconstituted BOTOX before injecting it to get rid of any air bubbles.
- To deliver BOTOX, use a flexible or rigid cystoscope.
- Place the needle 2 mm into the detrusor using the required volume and without touching the trigone.
- Approximately 1 centimetre should separate each injection.
- Drain the saline from the patient's bladder after the surgery, and continue to watch them for at least 30 minutes.
- In situations of the overactive bladder, a spontaneous void should also occur before the patient leaves the clinic.
-
Blepharospasm:
- Use a needle that is 27 or 30 gauge.
- Avoid injecting close to the medial lower lid and the levator palpebrae superioris.
- To avoid ecchymosis, pressure should be administered to the injection site.
-
Cervical dystonia:
- For the deep muscles, use a longer 22 gauge needle and a larger 25, 27, or 30 gauge needle. To pinpoint the affected muscles' locations, electromyography may be utilised.
-
Chronic migraines:
- 5 units per 0.1 mL should be injected into each of the 31 locations using a 0.5 inch, 30 gauge needle.
Spasticity as in cerebral palsy and related conditions:
- Use a needle between 23 and 26 gauge.
- Administer the medication to the afflicted limb's medial and lateral gastrocnemius muscles.
-
Spasticity in the upper or lower limb:
- For the deeper muscles, use a longer 22 gauge needle instead of a shorter 25, 27, or 30 gauge needle.
- The affected muscles can be identified using nerve stimulation or electromyography.
-
Strabismus injections:
- When using BOTOX to treat strabismus, electromyographic guidance or surgical exposure are necessary.
- The placement of the medication into the target muscle may be guided by the electrical activity detected at the injection needle's tip.
- A topical anaesthetic and an eye decongestant should be administered prior to the injection.
- 0.05 to 0.15 ml may be injected per muscle, however, the majority of patients will need further doses.
-
Primary axillary hyperhidrosis:
- At a 45° angle, inject intradermally to a depth of roughly 2 mm.
- Prior to the injection, the injection location should be designated and characterised using common staining methods such as Minor's Iodine-Starch Test.
- Instructions for Test:
- The patient should shave their underarms prior to the test and wait 24 hours before applying deodorants or antiperspirants.
- The patient should take a 30-minute nap and abstain from hot liquids.
- After drying, an iodine solution should be administered to the underarm region.
- The starch powder should be sparingly dusted over the surface once it has dried.
- In approximately 10 minutes, the sweating area should be a deep blue-black hue when the extra powder is blown off.
Administration of BOTOX for cosmetic purposes
-
Reduction of glabellar lines:
- Use a needle between 30 and 33 gauge.
- inject into every one of the five places (2 injections in each corrugator muscle and 1 injection in the procerus muscle).
- Utilize the smallest volume feasible and stay away from the levator palpebrae superioris while injecting.
-
Reduction of forehead lines:
- Use a needle of 30 to 33 gauge.
- Five locations in the frontalis muscle should get injections.
-
Reduction of lateral canthal lines:
- Make use of a 30 to 33-gauge needle.
- The bevel tip of the needle should be injected up and away from the eye.
- Inject the lateral orbicularis oculi muscle at 3 places on each side (a total of 6 injection points).
Mechanism of action of BOTOX (Botulinum toxin A):
- The neurotoxin BOTOX is created by the bacterium Clostridium botulinum and is sometimes referred to as Ona botulinum toxin A (formerly known as botulinum toxin type A).
- The anaerobic spore-forming bacterium Clostridium botulinum produces the botox toxin, which prevents the calcium-dependent release of acetylcholine in the presynaptic membrane of the neuromuscular junction in humans. Denervation is the term for this disorder.
- Muscle inactivation lasts as long as junction plates do not develop from new fibrils that emerge from the nerves.
- By blocking the release of acetylcholine, botox injections intratumorally alter the efferent pathways of detrusor activity.
- When botox is injected intradermally, sweat glands are momentarily rendered inactive, which lessens localised perspiration.
Improvement in the symptoms may be noted as follows:
- Improvement in blepharospasm is noted in 3 - 4 days.
- Improvement in Cervical dystonia is noted in 2 weeks.
- Improvement in Detrusor overactivity is noted in about 2 weeks.
- Improvement in the reduction of glabellar lines may be seen in 1 - 2 days
- Improvement in Spasticity in patients with focal and cerebral palsy may be noted in 2 weeks or less time.
- Improvement in strabismus may be observed in 1 - 2 days
Duration of action of BOTOX:
It is effective for the following duration:
- Blepharospasm:
- 3 to 4 months
- Detrusor overactivity associated with the neurologic condition:
- 42 - 48 weeks
- Cervical dystonia:
- 3 - 4 months
- Primary axillary hyperhidrosis:
- For a mean duration of 201 days.
- Spasticity:
- 3 - 3.5 months
- Reduction of glabellar lines:
- 3 - 4 months
- Strabismus:
- 2 - 6 weeks
- 2 - 6 weeks
It is not absorbed when administered Intramuscularly at the recommended doses.
