Long-lasting symptom control from a liquid non-stimulant1

Effective when combined with a stimulant or when used alone2,3

Monotherapy:

  • The effectiveness of clonidine XR has been assessed in a clinical study in children 6 to 17 years old with ADHD. Patients were randomly assigned to 1 of 3 treatment groups: clonidine XR 0.2 mg/day, clonidine XR 0.4 mg/day, or placebo, and for those who were given clonidine the dose was gradually increased until they had reached their fixed doses. Patients remained on the medication for eight weeks while others took a placebo. Each week, each child's attention and behavior was measured using ADHD-RS-IV scores.2
  • At week 5, patients in the clonidine XR groups had significantly greater improvement in inattention and hyperactivity scores from baseline than those in the placebo group.2
  • The most common adverse events in the study were somnolence, fatigue, irritability, pharyngolaryngeal pain, increased body temperature, ear pain, emotional disorder, nightmare, insomnia, constipation and dry mouth.2

Combined with stimulants:

  • The effectiveness of clonidine XR has been assessed in a clinical study in children 6 to 17 years old with ADHD who had been previously treated with stimulants and had inadequate response. In combination with their baseline stimulant medication, each patient was given either placebo or clonidine XR and the dose of clonidine XR was gradually titrated until they had reached their flexible doses. Each child's attention and behavior was measured weekly using ADHD-RS-IV scores.3
  • At 5 weeks, patients in the clonidine XR + stimulant group improved from baseline in ADHD symptoms measured by ADHD-RS-IV scores compared to those taking placebo + stimulant.3
  • The most common adverse events in the study were somnolence, fatigue, headache, upper abdominal pain, nasal congestion, pharyngolaryngeal pain, cough, irritability, insomnia, dizziness, and increased body temperature.3

Important Safety Information

Who should not take ONYDA XR?

  • Do not take ONYDA XR if you are allergic to clonidine.

ONYDA XR can cause serious side effects including:

  • Allergic reactions: You may develop an allergic reaction to ONYDA XR if you had an allergic reaction to clonidine taken through your skin in a patch. Stop taking ONYDA XR and call your healthcare provider right away or go to the nearest emergency room if you develop any signs or symptoms of an allergic reaction, including:
    • skin rash
    • hives
    • swelling of the eyes, face, lips, or tongue
  • Decreased blood pressure and heart rate. ONYDA XR can decrease your blood pressure and heart rate, which can increase your chance of passing out (syncope). If you have a history of passing out or have other medical problems as mentioned above, your risk is higher. Your healthcare provider should check your heart rate and blood pressure before starting treatment and regularly during treatment with ONYDA XR. Do not become dehydrated or too hot (overheated) to decrease your chance of passing out during treatment with ONYDA XR. Before taking ONYDA XR, tell your healthcare provider about all of your medical conditions, including if you: have kidney problems, have low or high blood pressure, have heart problems, including slow heart rate or other heart rhythm problems, had a stroke or have stroke symptoms.
  • Sleepiness and tiredness that could cause slow reaction times (sedation and somnolence). Do not drive, operate heavy machinery, or do other dangerous activities until you know how ONYDA XR affects you because ONYDA XR can cause sleepiness and tiredness that could cause slow reaction times. Do not drink alcohol or take other medicines that make you sleepy or dizzy during treatment with ONYDA XR until you talk with your healthcare provider.
  • Rebound high blood pressure (hypertension). Suddenly stopping ONYDA XR can cause high blood pressure to return if you have a history of high blood pressure. Suddenly stopping ONYDA XR may also cause withdrawal symptoms including headache, increased heart rate, nausea, flushing or warm feeling, lightheadedness, tightness in your chest and nervousness or anxiety. Do not suddenly stop ONYDA XR treatment without first talking to your healthcare provider.

The most common side effects of ONYDA XR when used alone include:

  • falling asleep or sleepiness and tiredness that could cause slow reaction times
  • irritability

  • dry mouth

The most common side effects of ONYDA XR when used with other ADHD medicines include:

  • falling asleep or sleepiness and tiredness that could cause slow reaction times

ONYDA XR may cause fertility problems in females and males, which may affect your ability to have a child. Talk to your healthcare provider if this is a concern for you.

These are not all of the possible side effects of ONYDA XR. Call your doctor for medical advice about side effects.

ONYDA XR and certain other medicines may affect each other causing serious side effects. Especially tell your healthcare provider if you take:

Before taking ONYDA XR, tell your healthcare provider, if you:

  • are pregnant or plan to become pregnant. It is not known if ONYDA XR will harm the unborn baby.
    There is a pregnancy registry for females who are exposed to ADHD medications, including ONYDA XR, during pregnancy. The purpose of the registry is to collect information about the health of females exposed to ONYDA XR and their baby. If you become pregnant during treatment with ONYDA XR, talk to your healthcare provider about registering with the National Pregnancy Registry of ADHD Medications at 1-866-961-2388 or visit online at https://womensmentalhealth.org/adhdmedications/.
  • are breastfeeding or plan to breastfeed. ONYDA XR passes into the breast milk. Babies who are breastfed during treatment with ONYDA XR may become very sleepy, develop relaxed or floppy muscles, and develop trouble breathing. Call the baby’s healthcare provider if the baby is breastfed during treatment with ONYDA XR and develops any of these symptoms. Talk to your healthcare provider about the best way to feed your baby if you take ONYDA XR.
