ADHD Home > Quillivant XR Warnings and Precautions
Some of the conditions you should tell your doctor about before taking Quillivant XR include heart problems, high blood pressure, and mental illness. This drug is not suitable for everyone, so be sure you understand the risks of dependence, abuse, and drug interactions before starting treatment with Quillivant XR. Warnings and precautions also apply to people with certain allergies or who are taking an MAOI.
- Heart problems of any kind, including heart disease, heart defects, or a heart arrhythmia (abnormal heart rhythm)
- High blood pressure (hypertension)
- A mental health or psychiatric problem, such as depression, bipolar disorder, or a psychotic disorder
- A family history of depression, bipolar disorder, or suicide
- A history of drug or alcohol abuse or dependence
- Any allergies, including to foods, dyes, or preservatives.
- Pregnant or thinking of becoming pregnant
- Medications that contain methylphenidate, such as Quillivant XR, have a high potential for dependence and abuse. Because of this potential, these medications are considered "controlled substances," and strict rules and regulations must be followed when using them.
Let your healthcare provider know if you have the desire to take more Quillivant XR than prescribed, to take it for a reason other than why it was prescribed, or if you feel you may be developing a problem with Quillivant XR abuse.
- Medications such as Quillivant XR have been reported to cause heart-related problems, including heart attacks and strokes in adults and sudden death in people with underlying heart conditions. Let your healthcare provider know if you develop signs of heart problems during treatment, such as chest pain, shortness of breath, fainting, or an abnormal heartbeat.
- Quillivant XR could increase your blood pressure and heart rate (pulse). Your healthcare provider should monitor you for these potential side effects.
- Stimulants used to treat ADHD have been associated with problems in blood vessels in the fingers and toes, sometimes causing problems such as Raynaud's disease. Alert your healthcare provider to any signs of this problem, such as cold or numb toes or fingers.
- This medication may worsen symptoms of bipolar or psychotic disorders, such as schizophrenia. It could also cause hallucinations (seeing or hearing things that are not real), delusions (believing things that are not true), or mania (an abnormal elevation in mood), even in people who have never had these symptoms in the past. Let your healthcare provider know if you develop any new or worsening changes in your mood, thoughts, or behavior.
- Stimulant medications, such as Quillivant XR, may cause weight loss and slow down growth in children. This slowing down of growth is usually small (a decrease of about 0.8 inches in height and 5.9 pounds in weight over three years). Children who are treated with Quillivant XR should have their height and weight monitored throughout treatment, and may need to stop treatment if they are not growing as expected.
- There have been reports of priapism in people taking ADHD medications, including this one. This side effect is an abnormally long-lasting, painful erection and can cause serious, permanent damage to the penis. It can occur in males of any age. Young boys might not recognize this side effect, and males of any age might be hesitant to seek parental or medical attention, due to embarrassment. Prompt treatment is necessary to avoid damage.
- Quillivant XR may react with several other medications (see Quillivant XR Drug Interactions).
- Quillivant XR is a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are currently unknown (see Quillivant XR and Pregnancy).
- Quillivant XR passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Quillivant XR and Breastfeeding).
