What is the dosage for methylphenidate?
The dose of methylphenidate is adjusted based on patients' responses. It may be given once, twice, or three times daily depending on formulation.
The recommended dose for Concerta is 18-72 mg once daily.
The recommended dose for Ritalin LA is 10-60 mg once daily and for regular Ritalin the recommended dose is 10-60 mg daily in 2 or 3 divided doses.
Which drugs or supplements interact with methylphenidate?
The stimulation effects of methylphenidate on the CNS can be additive when used with other chemicals and medications that stimulate the CNS, such as caffeine (found in coffee, tea, or cola drinks), and pseudoephedrine or phenylpropanolamine (found in many cough-and-cold preparations). The combination of methylphenidate and monoamine oxidase inhibitors (MAOIs), for example, isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), and procarbazine (Matulane), should not be taken with methylphenidate since a hypertensive crisis (severely high blood pressure) may occur. Moreover, methylphenidate should not be given to any patient within 14 days of receiving such an inhibitor. The blood pressure lowering effects of medications used to treat hypertension may be reduced by methylphenidate. As a result, blood pressure needs to be monitored when starting or stopping methylphenidate in patients who are receiving medications for controlling their blood pressure.
PREGNANCY There are no adequate studies of methylphenidate in pregnant women.
