Ritalin (methylphenidate)
Ritalin (methylphenidate) is a central nervous system stimulant prescribed for ADHD and narcolepsy. At HealthDeliver Clinic, patients already prescribed methylphenidate can consult a doctor and refill their prescription in Bangkok, with proper medical review at every step.
Who this refill service is for
This is a prescription-refill service for patients who have already been diagnosed with ADHD or narcolepsy and prescribed methylphenidate, and who need to continue their treatment while in Thailand. A doctor consultation and assessment is required before any medication is dispensed. Methylphenidate is a controlled medication — we do not supply it without medical review and a valid clinical need.
What is Ritalin?
Ritalin is a brand of methylphenidate, a stimulant that increases dopamine and noradrenaline activity in the brain. In people with ADHD, this improves focus, attention, and impulse control; in narcolepsy, it helps manage excessive daytime sleepiness. It’s available as immediate-release tablets and extended-release formulations.
Uses
- ADHD: improves attention and focus, reduces hyperactivity and impulsivity
- Narcolepsy: helps control excessive daytime sleepiness
How it’s taken
- Immediate-release tablets: usually taken 2–3 times daily, before meals, as directed
- Extended-release: usually taken once in the morning
Dosing is individual and set by your doctor. Always follow your prescription for the correct dose and timing — do not adjust it yourself.
Possible side effects
Common: reduced appetite, difficulty sleeping, nervousness, headache, increased heart rate.
Less common but serious: chest pain, breathing difficulty, mood changes, signs of circulation problems. Seek medical help immediately if these occur.
Precautions
Methylphenidate is a controlled medication with a potential for misuse and dependency, and must be taken exactly as prescribed.
