ADHD Home > Metadate ER Dosage
People typically start with immediate-release methylphenidate and then switch to an extended-release version, like Metadate ER. The dosage for this drug will start at 20 mg a day if your previous methylphenidate dose was 10 mg twice daily. If you were taking 20 mg twice a day, your new Metadate ER dosage would be 40 mg a day.
The dose of Metadate ER® (methylphenidate extended-release) that your healthcare provider prescribes will vary, depending on a number of factors, including:
- Your age
- Other narcolepsy or ADHD medications you may have tried
- Other medical conditions you may have
- Other medications you are currently taking.
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
Metadate ER is intended to replace immediate-release methylphenidate tablets (such as Ritalin®) once you have found the dose that works best for you. You should start with immediate-release methylphenidate. Once you are stable on a specific dose of this drug, your healthcare provider may switch you to Metadate ER (which is taken just once a day instead of twice a day).
If you were taking methylphenidate 10 mg twice a day, your new Metadate ER dose would be 20 mg, taken once daily in the morning. If you were taking methylphenidate 20 mg twice a day, your new Metadate ER dose would be 40 mg, taken once daily in the morning.
Considerations for people taking Metadate ER include the following:
- If you do not take your Metadate ER as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your regular schedule. Taking a dose after morning may cause trouble sleeping. Do not take a double dose.
- Your Metadate ER dose can be taken with or without food. If the medicine upsets your stomach, try taking it with food.
- For the medication to work properly, you have to take it as prescribed. It will not work if you take it differently than how your healthcare provider recommends.
- If you are unsure about anything related to Metadate ER or your Metadate ER dosage, talk to your doctor, nurse, or pharmacist. Do not stop taking the medicine without first discussing it with your healthcare provider.
