How should I take Concerta?
Take Concerta exactly as prescribed by your doctor. Using this medicine improperly can cause death or serious side effects on the heart.
Concerta extended-release tablets are taken once each day in the morning. Concerta is an extended-release tablet. It releases methylphenidate into your or your child’s body throughout the day.
Concerta extended-release tablets can be taken with or without food. Follow the directions on your medicine label
The extended-release tablet does not dissolve completely in the body after all the medicine has been released. You or your child may sometimes notice the empty tablet in a bowel movement. This is normal.
Do not crush, chew, or break a Concerta extended-release tablet. Swallow the tablet whole. Breaking the tablet may cause too much of the drug to be released at one time.
While using Concerta, your doctor will need to check your progress at regular visits. Your heart rate, blood pressure, height and weight may also need to be checked often.
From time to time, your doctor may stop treatment for a while to check ADHD symptoms.
If you need surgery, tell the surgeon ahead of time that you are using Concerta. You may need to stop using the medicine for a short time.
Methylphenidate may be habit-forming. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. Selling or giving away this medicine is against the law.
Store at room temperature away from moisture and heat.
Keep track of the number of Concerta extended-release tablets used from each new bottle. Methylphenidate is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
