There are a number of less common (but more serious)
Concerta side effects that you should report to your healthcare provider, including, but not limited to:
- Suicidal thoughts
- Confusion
- Anxiety
- Chest tightness or chest pain or heart palpitations
- A rapid heart rate (tachycardia)
- Shortness of breath
- Depression (see Concerta and Depression)
- More outgoing or aggressive behavior than normal
- Strange behavior, agitation, or restlessness
- Hallucinations (seeing, hearing, or feeling things that are not really there)
- Fainting or seizures
- Uncontrolled movements of the head, neck, mouth, arms, or legs (known as tics)
- Signs of an allergic reaction, including an unexplained skin rash, itching, hives, wheezing or trouble breathing, or unexplained swelling.
You may experience some or none of the Concerta side effects explained above. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, be sure to let your healthcare provider know if you develop any side effects while taking Concerta. Also, let your healthcare provider know if you develop something that "just does not seem right." While the issue may not be due to a side effect, your healthcare provider will be able to diagnose and treat the problem.
