Central Nervous System (CNS) Stimulant
Last reviewed June 2026
Who is this for?
Methylphenidate (sold as Ritalin in Nigeria) is a stimulant medicine that works by increasing certain natural chemicals in the brain to help improve focus, attention, and self-control.
Inhibits the reuptake of norepinephrine and dopamine at the presynaptic neuron, increasing their synaptic concentration and enhancing catecholaminergic neurotransmission in the central nervous system. This potentiation of monoaminergic activity improves attention, reduces impulsivity, and promotes wakefulness.

For adults, the usual starting dose is one 10 mg tablet taken 2 to 3 times a day, 30 to 45 minutes before meals. Your doctor will adjust the dose based on how you respond. Take it in the morning and afternoon — avoid taking it late in the evening as it can stop you from sleeping. Swallow the tablet with water.
If you miss a dose, take it as soon as you remember — but if it is already late afternoon or evening, skip it and take your next dose at the normal time. Do not take a double dose to make up for the missed one, as this can cause serious side effects.
Ritalin is a controlled substance in Nigeria — do not share it with anyone else, as misuse can be dangerous and is illegal. Only buy from a licensed pharmacy with a valid doctor's prescription; do not purchase from roadside sellers or unverified online sources. Monitor your weight and appetite closely, especially in children, as this drug can cause significant weight loss over time.
Do not take methylphenidate with MAO inhibitor drugs (some types of antidepressants) as this can cause a dangerously high blood pressure crisis. Be careful if you are taking blood pressure medicines, as methylphenidate can affect how well they work. Avoid alcohol while on this medicine, as it can worsen side effects like dizziness and heart problems.
