How Can I Stay Healthy While Taking Focalin?

Although Focalin helps you cope with ADHD, it may cause harmful reactions, including sudden death and seizure.

If you or your child are coping with ADHD, additional ways to support your family include behavioral therapy for both you and your children and organizational and social skills training. Studies have shown that biofeedback may be a viable therapy to help support the development of attention in adults and children. There is also evidence that ADHD may have roots in adverse childhood experiences. While it's not the root cause for everyone, addressing trauma with a licensed therapist may be a step in your healing process. Speak with your or your child's healthcare provider about different approaches and treatment options. 

It's important to note that several medical conditions can be mistaken for ADHD, for example, anemia (low iron levels), hypothyroidism (low thyroid function), or prolonged sleep disturbances. You and your healthcare provider must rule these out first to make a definitive diagnosis of ADHD. For example, studies show that sleep disturbances may increase a child's odds of developing ADHD over time. Your healthcare provider can help you discuss sleep hygiene and rule out or address any potential sleep disorders (ex., sleep apnea, restless leg syndrome) in yourself or your child before starting the process of an ADHD diagnosis. Other conditions that need to be ruled out before making a precise ADHD diagnosis include anxiety, depression, learning disorders (ex., dyslexia), and vision or hearing problems. Work with your or your child's healthcare provider to help figure out the root cause of your or your child's issue.

To stay healthy:

  • Be sure to ask your or your child's healthcare provider about evaluating you or your child for any nutritional deficiencies or conditions that may contribute to tiredness or inattention, such as low iron levels, thyroid conditions, or sleep disturbances.
  • Be sure to have your child's healthcare provider monitor them for any decrease in growth, which may happen with stimulants like Focalin.
  • Tell your healthcare provider about all your health problems, including if you have glaucoma, heart problems, or seizure disorder. 
  • Continue taking your medicine even if you feel better.
  • Do not share your pills. Keep this medicine locked in a safe place.
  • Report all side effects you experience to your healthcare provider.
