Yes — the active ingredient is metabolized by a gene known to vary between individuals.
Relevant genes: BCHE
Mivacron is affected by pharmacogenetics through the BCHE gene. Your genotype for this gene can change how your body processes Mivacron, which can affect both how well it works and how well you tolerate it. The strongest evidence level on this page is Strong, based on CPIC or FDA guidelines.
Published guidance from FDA on how mivacurium should be dosed or substituted based on your BCHE phenotype.
| Phenotype | What it means | Recommendation | Evidence |
|---|---|---|---|
|
Intermediate Metabolizer
BCHE
|
Your genetic result suggests you may process this anesthetic more slowly, increasing the risk of prolonged muscle effects; your doctor may choose a different medicine. |
FDA
Avoid use of mivacurium or use with extreme caution and close monitoring; consider alternative agents.

|
Poor Metabolizer
BCHE
|
Because your body processes this drug much more slowly, there’s a higher risk of long-lasting muscle effects; your doctor will likely choose another option. |
FDA
Avoid use of mivacurium; select alternative agents not affected by BCHE activity.

Normal Metabolizer
BCHE
|
Your genetic result suggests you should process this medicine normally, but your doctor will manage dosing as usual. |
FDA
Initiate therapy with recommended starting dose and adjust per standard clinical practice.

|
Indeterminate
BCHE
|
The impact of your genotype on response to this drug is unknown. |
FDA
Initiate therapy with recommended starting dose.
