Botox 100 Unit

Beskrivelse

Botox 100 Unit (onabotulinumtoxinA) is the flagship formulation of botulinum toxin type A produced by Allergan (now part of AbbVie). It contains 100 units of purified neurotoxin complex and is supplied as a vacuum-dried powder in a single-use vial, reconstituted with preservative-free 0.9% sodium chloride solution before injection. Botox works by blocking the release of acetylcholine at the neuromuscular junction, causing dose-dependent, reversible relaxation of injected muscles or inhibition of glandular secretion—making it the gold standard for both aesthetic and therapeutic neuromodulation.

Aesthetic Uses

Botox 100 Unit is FDA-approved and globally recognized for the temporary improvement of moderate to severe:

• Glabellar frown lines
• Lateral canthal lines (crow’s feet)
• Horizontal forehead lines
• Additional off-label aesthetic indications include bunny lines, perioral rhytids, chin dimpling, masseter hypertrophy (jaw slimming), platysmal bands, and gummy smile correction

Typical cosmetic doses range from 20–60 units per treatment session, with results appearing within 3–7 days, peaking at 10–14 days, and lasting 3–5 months (sometimes longer with repeated consistent treatments). The 100-unit vial is versatile for full-face treatments or multiple patients in busy clinics.

Therapeutic Uses

Botox 100 Unit is approved for numerous medical conditions, including:

• Chronic migraine (≥15 headache days/month)
• Cervical dystonia (abnormal head position and neck pain)
• Upper and lower limb spasticity (adult and pediatric)
• Overactive bladder and neurogenic detrusor overactivity
• Severe primary axillary hyperhidrosis
• Blepharospasm and strabismus
• Sialorrhea (chronic drooling) in adults

Therapeutic doses vary widely (e.g., 155–195 units for chronic migraine, 200–300 units for spasticity), requiring precise anatomical knowledge and often electromyography guidance.

Administration & Handling

• Reconstitute with 2.5 mL (for 4 U/0.1 mL) or 1.0–4.0 mL of sterile, preservative-free saline, depending on desired concentration
• Use within 24 hours when refrigerated (2–8°C)
• Administer via fine-gauge needles (30–33G) or cannulas in aesthetic applications

Safety & Side Effects

Common side effects are mild and transient: injection-site pain, swelling, bruising, headache, eyelid ptosis, dry eyes, or flu-like symptoms. Serious risks (rare) include distant spread of toxin effects (dysphagia, respiratory distress), allergic reactions, or antibody-induced treatment failure with long-term use. Contraindications include known hypersensitivity to botulinum toxin or human albumin, active infection at injection site, and certain neuromuscular disorders (e.g., myasthenia gravis, ALS).

As of 2026, Botox remains the most studied and widely used botulinum toxin worldwide, with billions of units safely administered over decades. The 100-unit vial offers flexibility for both aesthetic and therapeutic applications. Botox must be administered only by qualified healthcare professionals (dermatologists, plastic surgeons, neurologists, ophthalmologists, urologists, etc.) trained in botulinum toxin injection techniques, with proper patient selection, informed consent, and follow-up. Always use genuine Botox from authorized distributors to ensure safety and efficacy.
