Drug Interactions between Concerta and house dust mite allergen extract

Do not use alcohol or medications that contain alcohol while you are receiving treatment with methylphenidate. This may increase nervous system side effects such as drowsiness, anxiety, depression, and seizures. In addition, with certain long-acting forms of methylphenidate, alcohol can cause too much of the drug to be released at one time. High blood levels of the drug may increase the risk of side effects. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
