IMPORTANT SAFETY INFORMATION

JORNAY PM is a federally controlled substance (CII) because it contains methylphenidate and has a high chance of abuse and misuse and may lead to substance use problems, including addiction. Misuse and abuse of JORNAY PM can lead to overdose and death, which is increased with higher doses of JORNAY PM or if it is used in ways that are not approved, such as snorting or injection. Your healthcare provider (HCP) should check for signs of abuse, misuse, and addiction before starting and during treatment with JORNAY PM. JORNAY PM may lead to physical dependence after prolonged use, even if taken as directed by your HCP. Tell your HCP if you or your child have ever abused or been dependent on alcohol, prescription medicines, or street drugs.


JORNAY PM can be a target for people who abuse prescription medicines or street drugs. Keep JORNAY PM in a safe place to protect it from theft. Never give your JORNAY PM to anyone else, because it may cause death or harm them. Selling or giving away JORNAY PM may harm others and is against the law.

JORNAY PM should not be taken if you or your child is allergic to methylphenidate or any of the ingredients in JORNAY PM or is taking or has taken an antidepressant called a monoamine oxidase inhibitor (MAOI) within the last 14 days.

JORNAY PM may cause other serious side effects, including:

  • Risks for people with serious heart disease. Sudden death has happened in people who have heart defects or other serious heart disease. Your HCP should check carefully for heart problems before starting JORNAY PM. Tell your HCP about any heart problems, heart disease, or heart defects. Call your HCP or go to the nearest hospital emergency room right away if there are any signs of heart problems, such as chest pain, shortness of breath, or fainting during treatment.
  • Increased blood pressure and heart rate. Blood pressure and heart rate should be checked regularly during treatment.
  • Mental (psychiatric) problems, including new or worse behavior and thought problems, new or worse bipolar illness, new psychotic symptoms (such as hearing voices or seeing or believing things that are not real) or new manic symptoms. Tell your HCP about any mental problems, or about a family history of suicide, bipolar illness, or depression. Call your HCP right away if there are any new or worsening mental symptoms or problems during treatment.
  • Painful and prolonged erections (priapism) in males. If painful and prolonged erections happen, get medical help right away.
  • Circulation problems in fingers and toes (peripheral vasculopathy, including Raynaud’s phenomenon). Signs and symptoms may include fingers or toes feeling numb, cool, painful, sensitive to temperature, and/or changing color from pale, to blue, to red. Tell your HCP about any circulation problems in fingers or toes. Call your HCP right away if any signs of unexplained wounds appear on fingers or toes.
  • Slowing of growth (height and weight) in children. Children should have their height and weight checked often while taking JORNAY PM.
  • Eye problems (increased pressure in the eye and glaucoma). Tell your HCP about any eye problems. Call your HCP right away if changes in vision or eye pain, swelling, or redness occurs.
  • New or worsening tics or worsening Tourette’s syndrome. Tell your HCP if any new or worsening tics or worsening Tourette’s syndrome occurs.

Before taking JORNAY PM, tell your HCP if you or your child:

  • are pregnant or plan to become pregnant. It is not known if JORNAY PM will harm an unborn baby.
  • are breastfeeding or plan to breastfeed. JORNAY PM passes into the breast milk.

Tell your HCP about all of the medicines that you or your child takes, including prescription and over-the-counter medicines, vitamins, and herbal supplements. JORNAY PM and some medicines may interact with each other and cause serious side effects. Especially tell your HCP if you or your child takes medicine to treat depression, including MAOIs.

Avoid drinking alcohol during treatment with JORNAY PM. This may cause a faster release of the medicine in JORNAY PM.

The most common side effects of methylphenidate include decreased appetite, trouble sleeping, nausea, vomiting, indigestion, stomach pain, weight loss, anxiety, dizziness, irritability, mood swings (affect lability), increased heart rate, and increased blood pressure.

The most common side effects of JORNAY PM in clinical studies in children ages 6 to 12 with ADHD include trouble sleeping, nausea, decreased appetite, restlessness (psychomotor hyperactivity), headache, nausea, mood swings, and vomiting. These are not all the possible side effects of JORNAY PM.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
