ARTICLE SUMMARY

A change in botulinum toxin effects does not always mean resistance. Dose, injection sites, muscle changes and product characteristics should be reviewed together before adjusting repeat intervals and cumulative dose.

What is botulinum toxin resistance?

It means a reduced expected response due to neutralizing antibodies against botulinum toxin.

However, reduced effects can have other causes, including treatment site, dose and muscle changes, which need to be distinguished.

What should be checked before repeat treatment?

Confirm recent treatment dates, products and doses by area as accurately as possible.

Avoid unnecessarily short repeat intervals and discuss the minimum effective dose for your goal with your clinician.

Can product selection alone prevent resistance?

Protein composition matters, but one product alone cannot determine the likelihood of resistance.

A record-based approach managing history, total dose and intervals together is important.

FAQ

Frequently asked questions

Q01Can I repeat treatment immediately if effects wear off quickly?

First assess why the effect declined. Plan around your treatment records and current muscle movement, rather than repeating at short intervals on your own.
