What it is
- methylphenidate (Ritalin, Concerta (ER), Metadate ER/CD) — cNS stimulant (dopamine/norepinephrine reuptake inhibitor); Schedule II.
- Used for: ADHD; Narcolepsy.
Usual adult dosing
- Adults – Ritalin IR tablets (label): Average 20–30 mg/day in 2–3 divided doses; max 60 mg/day (Give 30–45 min before meals; last dose before ~6 pm. Reassess if no improvement after 1 month of dose adjustment.)
- Extended-release products: Product-specific dosing (e.g., Concerta, Ritalin LA) (Not detailed in this beta – verify against the specific product label.)
Boxed warning
- Abuse, misuse, and addiction: high potential for abuse and misuse, which can lead to substance use disorder including addiction; misuse can result in overdose and death (risk higher with higher doses or non-oral routes such as snorting/injection). Assess risk before prescribing, educate about safe storage/disposal, and reassess frequently during treatment.
Monitor
- Blood pressure & heart rate [Baseline, after dose changes, periodically]
- Abuse / misuse / diversion risk [Every visit; before refills]
Nursing priorities
- Baseline BP, HR, weight (height/growth in children), sleep, appetite.
- Cardiac history, family history of sudden death or ventricular arrhythmia.
- Give early in the day (last dose before ~6 pm) to limit insomnia, unless otherwise ordered.
- Check BP and pulse at baseline, after dose changes, and periodically; report sustained elevations.
- Monitor weight/appetite; offer meals before dose/high-calorie snacks as appropriate.
Major interactions
- MAOIs (incl. linezolid, IV methylene blue) – within 14 days: Hypertensive crisis – contraindicated.
Key teaching
- Take it exactly as prescribed, usually in the morning. Taking it late in the day can keep you awake.
- Never share it, sell it, or take extra – it can be misused and is dangerous in overdose. Keep it locked up and dispose of leftovers safely.
- It can lower your appetite, raise your heart rate and blood pressure, and make it hard to sleep. Eat regular meals and have your vitals checked.
