Product Overview

Dysport® (abobotulinumtoxinA) is an Ipsen-manufactured prescription botulinum toxin type A medicine supplied in 300-Unit and 500-Unit single-dose vial presentations documented in US and UK labeling. Both contain a lyophilized toxin complex with human albumin and lactose excipients, and require refrigerated storage. The strengths can be compared by labeled potency, packaging, and market authorization; Dysport Units cannot be converted directly to those of other botulinum toxin products. Galderma markets Dysport for aesthetic uses in certain territories, while approved indications vary by country.

Key Features

Two established vial strengths. Dysport is documented as 300 Units and 500 Units per vial in US and UK product labeling; specific market availability varies.
AbobotulinumtoxinA formulation. The active substance is a botulinum toxin type A complex, also described in European labeling as a toxin–haemagglutinin complex.
Human albumin and lactose excipients. Both ingredients are identified in official prescribing information; the US label specifies 125 micrograms of human serum albumin and 2.5 mg lactose per vial.
Prescription-only, refrigerated product. Unopened vials are labeled for 2–8°C refrigerated storage, with market-specific additional handling provisions.
Product-specific potency Units. Dysport Units are defined by the product's own biological potency assay and cannot be converted directly into Units of other botulinum toxin brands.

How Dysport Works

AbobotulinumtoxinA acts at peripheral cholinergic nerve endings and inhibits the release of acetylcholine, a neurotransmitter required for muscle activation. Its botulinum toxin type A activity involves cleavage of SNAP-25, a protein involved in neurotransmitter release. This produces a temporary reduction in activity of the affected muscle. Neuromuscular transmission gradually recovers over time.

In the United States, Dysport has approved indications including adult cervical dystonia, spasticity in patients aged two years and older, and temporary improvement of moderate to severe glabellar lines in adults younger than 65 years. These are US-label examples, not universal approvals. Exact indications, eligibility and safety warnings must be checked in the relevant local prescribing information. Clinical action, duration and dosing must not be inferred by comparing Dysport's potency Units with those of other botulinum toxin products.

Available Vial Strengths: Dysport 300U & 500U

For professional product evaluation, compare the labeled Dysport potency, the exact pack configuration, cold-chain requirements, and the authorization applicable to the destination country. Both formulations contain abobotulinumtoxinA; a higher vial strength is not evidence of broader approval or interchangeable dosing.

Comparison of documented Dysport strengths
Product	Labeled Potency	Dosage Form	Packaging / Market Note
Dysport 300U	300 Dysport Units per vial	Lyophilized powder	Single-dose vial; authorized in the US and UK, among other markets
Dysport 500U	500 Dysport Units per vial	Lyophilized powder	Single-dose vial; documented in the US, UK and South Korean drug records

Other regional presentations and brand names may exist. This comparison is limited to the 300U and 500U strengths documented in the cited US and UK labels; availability at TEOSQUARE is determined separately by its live product options.

Professional Product Selection Considerations

When comparing Dysport 300U and 500U product options, identify the strength printed on the original vial, the package size, the local prescribing-information version, and the destination-market authorization. A 300-Unit vial is not automatically approved in every country that authorizes a 500-Unit vial.

Strength and pack identity. Confirm the Dysport-specific potency and the exact number of single-dose vials in the commercial carton.
Market-specific labeling. Verify the locally approved indications, warnings, and any eligibility or distribution restrictions for the intended destination.
Cold-chain requirements. Match storage and transport planning to the label for the supplied market; do not generalize limited temperature-excursion provisions from a different jurisdiction.

Storage & Handling

Unopened Dysport vials should be stored refrigerated at 2–8°C and must not be frozen. The US label also specifies protection from light. The current UK SmPC permits a specific, limited temperature excursion for unopened vials, but this exception should not be applied to products from other markets without confirming their own labeling.

Dysport is a prescription medicine for administration by appropriately qualified healthcare professionals. Follow the exact market-specific package insert for professional handling and use; no preparation or administration protocol is provided here. The product carries serious warnings concerning the potential spread of toxin effects, including swallowing or breathing difficulties. The US label also cautions that Dysport may contain trace amounts of cow's milk proteins. Inspect the original packaging, authentication features and expiration date before professional use.

Frequently Asked Questions

Who manufactures Dysport?

Dysport is manufactured by Ipsen Biopharm Ltd. in the United Kingdom, according to the US prescribing information. Galderma markets Dysport for aesthetic indications in selected territories, which does not make it the manufacturer.

What is the difference between Dysport 300U and Dysport 500U?

The two presentations contain 300 or 500 Dysport-specific potency Units per vial, respectively. Both are lyophilized abobotulinumtoxinA products, but their authorized indications, available pack formats and local prescribing instructions must be checked by market.

Is Dysport the same as Botox?

No. Dysport contains abobotulinumtoxinA, whereas Botox contains onabotulinumtoxinA. Both are botulinum toxin type A medicines, but their potency Units are product-specific and must not be directly converted or treated as interchangeable.

Does Dysport contain human serum albumin?

Yes. Official US and UK product information lists human albumin and lactose. The US label specifies 125 mcg human serum albumin and 2.5 mg lactose per 300U or 500U vial.

How should unopened Dysport vials be stored?

The standard labeled requirement is refrigeration at 2–8°C without freezing. The UK SmPC includes a limited unopened-vial temperature-excursion provision; do not assume it applies to other jurisdictions or shipments.

What should a professional buyer verify when comparing Dysport vial strengths?

Check the exact 300U or 500U label, pack quantity, destination-market authorization, product expiration date, and storage conditions. Dysport is a prescription product; distribution and eligibility rules vary by jurisdiction.
