Interactions

No Results
Contraindicated
Serious - Use Alternative
Significant - Monitor Closely
Minor
Contraindicated (0)
Serious - Use Alternative (2)
- metoclopramide intranasal
mirabegron will increase the level or effect of metoclopramide intranasal by affecting hepatic enzyme CYP2D6 metabolism. Avoid or Use Alternate Drug. Concurrent use of metoclopramide intranasal and strong CYP2D6 inhibitors is not recommended since the metoclopramide intranasal dose cannot be adjusted.
- ozanimod
ozanimod increases toxicity of mirabegron by sympathetic (adrenergic) effects, including increased blood pressure and heart rate. Avoid or Use Alternate Drug. Because the active metabolite of ozanimod inhibits MAO-B in vitro, there is a potential for serious adverse reactions, including hypertensive crisis. Therefore, coadministration of ozanimod with drugs that can increase norepinephrine or serotonin is not recommended. Monitor for hypertension with concomitant use.

Pregnancy & Lactation
Pregnancy
There are no studies with the use in pregnant women to inform drug-associated risk for birth defects or miscarriage
Animal data
- Administration to pregnant animals during organogenesis resulted in reversible skeletal variations (in rats) at 22-fold (via AUC) the maximum recommended human dose (MRHD) of 50 mg/day and decreased fetal body weights (in rabbits) at 14-fold the MRHD
- At maternally toxic exposures in rats (96-fold), decreased fetal weight and increased fetal mortality were observed and, in rabbits (36-fold), cardiac findings (fetal cardiomegaly and fetal dilated aortae) were observed
Lactation
There is no information on the presence of mirabegron in human milk, the effects on the breastfed child, or the effects on milk production
Mirabegron-related material was present in rat milk and in the stomach of nursing pups following administrations of a single 10 mg/kg oral dose of 14C-labeled mirabegron to lactating rats
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

MIRABEGRON EXTENDED-RELEASE - ORAL
(MIR-a-BEG-ron)
COMMON BRAND NAME(S): Myrbetriq
USES: This medication is used to treat overactive bladder. Overactive bladder is a problem with how your bladder stores urine that causes a sudden urge to urinate. The urge may be hard to control, and overactive bladder symptoms may include frequent urination, strong sudden urges to urinate, or involuntary loss of urine (incontinence). Mirabegron works by relaxing a certain bladder muscle (detrusor), which helps the bladder hold more urine and lessens symptoms of overactive bladder.

If you have any questions, ask your doctor or pharmacist.Take this medication by mouth as directed by your doctor, usually once daily.
