Warnings and Precautions (
5.6 HyperprolactinemiaAs with other drugs that antagonize dopamine D2receptors, risperidone elevates prolactin levels and the elevation persists during chronic administration. Risperidone is associated with higher levels of prolactin elevation than other antipsychotic agents.
Hyperprolactinemia may suppress hypothalamic GnRH, resulting in reduced pituitary gonadotropin secretion. This in turn may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds. Long-standing hyperprolactinemia may lead to decreased bone density in both female and male patients.
UZEDY is an atypical antipsychotic indicated:
- for the treatment of schizophrenia in adults. ()1.1 SchizophreniaUZEDY is indicated for the treatment of schizophrenia in adults.
- as monotherapy or as adjunctive therapy to lithium or valproate for the maintenance treatment of bipolar I disorder in adults. ()1.2 Bipolar DisorderUZEDY is indicated as monotherapy or as adjunctive therapy to lithium or valproate for the maintenance treatment of Bipolar I Disorder in adults.
- Establish tolerability with oral risperidone prior to initiating UZEDY. ()2.1 General Administration InformationFor patients who have never taken risperidone, establish tolerability with oral risperidone prior to initiating UZEDY.UZEDY must be administered by a healthcare professional as an abdominal or upper arm subcutaneous injection. Do not administer UZEDY by any other route.For detailed preparation and administration instructions,see Dosage and Administration.
- Administer UZEDY by subcutaneous injection in the abdomen or upper arm by a healthcare professional. Do not administer by any other route. ()2.1 General Administration InformationFor patients who have never taken risperidone, establish tolerability with oral risperidone prior to initiating UZEDY.UZEDY must be administered by a healthcare professional as an abdominal or upper arm subcutaneous injection. Do not administer UZEDY by any other route.For detailed preparation and administration instructions,see Dosage and Administration.
- See Full Prescribing Information for important preparation and administration information. ()
2.7 Preparation and Administration Instructions- Read the instructions for preparation and administration below before administering UZEDY.
- For subcutaneous injection only. Do not inject by any other route.
- To be administered by a healthcare professional only.
- Allow UZEDY to come to room temperature for at least 30 minutes prior to administration.
- As a universal precaution, always wear gloves.
STEP 1Check to make sure UZEDY kit contains:
- One sterile single-dose, prefilled glass syringe
- One sterile 21G x 5/8” needle
Do not substitute any components of the kit for administration.

STEP 2Remove the kit from refrigerated storage and allow the package to sit at room temperature (20°C to 25°C [68°F to 77°F]) for at least 30 minutes.
Note: UZEDY is a solid at refrigerated temperatures and must reach room temperature prior to administration. Do not warm any other way and keep protected from light.
STEP 3Check that the drug in the syringe is white to off-white, opaque in color, and free from non-white particulate matter. Check that the pouch label states the needle size is 21G x 5/8”.
Do not use if any component of the kit is damaged or if the expiration date has passed.
STEP 4Expose the safety needle hub by peeling back the paper tab of the needle pouch. Set aside for use in Step 7.
STEP 5IMPORTANT:This step must be performed to ensure complete dosing. UZEDY is viscous and forceful downward flicks are required to move the bubble to the cap of the syringe. Failure to move the bubble to the cap of the syringe could result in incomplete dosage.Firmly hold the syringe by the white collar.
Flick Syringe Forcefully Three Times to Move the Bubble to the Cap- Flick with a forceful downward whipping motion of your full arm to move the bubble to the cap of the syringe.
- Repeat this action 3 times to ensure that the bubble is at the cap of the syringe.
Note: Standing while you do this may help achieve required force.
Check that the Bubble is at the Cap of the Syringe- The bubble will appear partially opaque.
- Holding the syringe up to light or against a dark backdrop may improve visibility.
- If the bubble is not at the cap, repeat Step 5 until it is.

STEP 6Hold the syringe vertically by the white collar. Bend and snap off the cap.
Do not touch the syringe tip to avoid contamination.
STEP 7Attach the Needle to the Syringe- Hold the syringe vertically with the white collar at the top.
- Push the green hub of safety needle inside the white collar of syringe and rotate the safety needle while holding the white collar until secure and tight.
Inspect the needle connection to check that the hub is not damaged.

STEP 8Select Injection Site from the Following Areas:- Stomach area (abdomen) around the belly button
- Back and outer area of the upper arms
Do not inject UZEDY anywhere except in the areas specified above.
Do not inject UZEDY into an area that is tender, red, bruised, callused, tattooed, hard, or has scars or stretch marks.
STEP 9Clean the Injection Site with an alcohol wipe.
STEP 10Remove the needle sheath by pulling the needle sheath away from the green hub to expose the needle.
Do not expel any visible air bubble.
STEP 11Pinch at least 1 inch of the area of cleaned skin with your free hand.
STEP 12Insert the needle into subcutaneous tissue (actual angle of injection will depend on the amount of subcutaneous tissue). Do not apply pressure to the plunger.
STEP 13Release the pinched skin once the needle is in the subcutaneous tissue.
STEP 14Inject the Medication- Push on the plunger using a slow, firm, and steady push until the entire dose is delivered.
- Inject the entire dose at one time, without interruption.
- Check that the plunger stopper is at the White Collar.
IMPORTANT: UZEDY is viscous. Resistance will be experienced during dose delivery. Do not use excessive force in an attempt to deliver UZEDY faster.

STEP 15Wait 2-3 seconds after the entire dose is delivered before removing the needle. Slowly pull the needle out from the injection site at the same angle as insertion.
STEP 16Activate (lock) the safety needle shield using one of the following methods:
- Surface Activation:Place the needle shield on a flat surface and pull the syringe backward until the needle shield covers the needle tip.

- Finger/Thumb Activation:Press either your thumb or finger on the needle shield and push it forward until the needle shield covers the needle tip.

There will be an audible click when the needle safety shield is locked.
Dispose of all syringe components in a suitable sharps container.

Pregnancy: May cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure. (
8.1 PregnancyThere is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including UZEDY, during pregnancy. Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or online at
Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery (
Oral administration of risperidone to pregnant mice caused cleft palate at doses 3- to 4-times the oral maximum recommended human dose (MRHD) of 16 mg/day with maternal toxicity observed at 4-times MRHD based on mg/m2body surface area. Risperidone was not teratogenic in rats or rabbits at doses up to 6-times the oral MRHD based on mg/m2body surface area. Increased stillbirths and decreased birth weight occurred after oral risperidone administration to pregnant rats at 1.5-times the oral MRHD based on mg/m2body surface area. Learning was impaired in offspring of rats when the dams were dosed at 0.6-times the oral MRHD and offspring mortality increased at doses 0.1- to 3-times the oral MRHD based on mg/m2body surface area.
The background risks of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
There is a risk to the mother from untreated schizophrenia or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide. Schizophrenia or bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors.
Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including risperidone, during the third trimester of pregnancy. These symptoms have varied in severity. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization.
Published data from observational studies, birth registries, and case reports on the use of atypical antipsychotics during pregnancy do not report a clear association with antipsychotics and major birth defects. A prospective observational study including 6 women treated with risperidone demonstrated placental passage of risperidone. A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk for major birth defects. There was a small increase in the risk of major birth defects (RR = 1.26, 95% CI = 1.02 to 1.56) and of cardiac malformations (RR = 1.26, 95% CI = 0.88 to 1.81) in a subgroup of 1566 women exposed to risperidone during the first trimester of pregnancy; however, there is no mechanism of action to explain the difference in malformation rates.
No developmental toxicity studies were conducted with subcutaneous risperidone suspension.
Oral administration of risperidone to pregnant mice during organogenesis caused cleft palate at 10 mg/kg/day which is 3-times the oral MRHD of 16 mg/day based on mg/m2body surface area; maternal toxicity occurred at 4-times the oral MRHD. Risperidone was not teratogenic when administered orally to rats at 0.6 to 10 mg/kg/day and rabbits at 0.3 to 5 mg/kg/day, which are up to 6-times the oral MRHD of 16 mg/day risperidone based on mg/m2body surface area. Learning was impaired in offspring of rats dosed orally throughout pregnancy at 1 mg/kg/day which is 0.6-times the oral MRHD and neuronal cell death increased in fetal brains of offspring of rats dosed during pregnancy at 1 and 2 mg/kg/day which are 0.6- and 1.2-times the oral MRHD based on mg/m2body surface area; postnatal development and growth of the offspring were also delayed.
Rat offspring mortality increased during the first 4 days of lactation when pregnant rats were dosed throughout gestation at 0.16 to 5 mg/kg/day which are 0.1- to 3-times the oral MRHD of 16 mg/day based on mg/m2body surface area. It is not known whether these deaths were due to a direct effect on the fetuses or pups or to effects on the dams; a no-effect dose could not be determined. The rate of stillbirths was increased at 2.5 mg/kg or 1.5-times the oral MRHD based on mg/m2body surface area.
In a rat cross-fostering study the number of live offspring was decreased, the number of stillbirths increased, and the birth weight was decreased in offspring of drug-treated pregnant rats. In addition, the number of deaths increased by Day 1 among offspring of drug-treated pregnant rats, regardless of whether or not the offspring were cross-fostered. Risperidone also appeared to impair maternal behavior in that offspring body weight gain and survival (from Day 1 to 4 of lactation) were reduced in offspring born to control but reared by drug-treated dams. All of these effects occurred at 5 mg/kg which is 3-times the oral MRHD based on mg/m2and the only dose tested in the study.
