What is Daxxify?

Daxxify is a longer-lasting botox (Botulinum toxin) injection used to reduce frown lines and for the treatment of cervical dystonia in adults. Daxxify (DaxibotulinumtoxinA-lanm) injection works by relaxing the affected muscles, which can reduce frown lines (glabellar lines) or the spasming and stiffness from cervical dystonia. Daxxify lasts longer than other first-generation botulinum toxins as it is formulated with a unique stabilizer (cell-penetrating peptide).

Daxxify is an acetylcholine release inhibitor and neuromuscular blocking agent. Daxxify works by blocking the transmission of specific chemical signals from nerves, mainly signals those cause muscles to contract. It works on frown lines by temporarily relaxing the facial muscles that cause the lines, which reduces their appearance. Daxxify works to treat cervical dystonia by relaxing muscles, which relieves abnormal involuntary movements and postures. 

Daxxify became an FDA-approved medicine on September 8, 2022, for moderate to severe frown lines (glabellar lines) in adults. Then on August 11, 2023, it became FDA-approved to treat cervical dystonia in adults. Approval for cervical dystonia was based on positive results from the Phase 3 clinical program (ASPEN 1, ASPEN OLS), which showed a median length of time that it lasted for cervical dystonia was 24.0 and 20.3 weeks for each trial.
