Biphasic pellet capsule: 30% releases immediately; 70% releases approximately 4–5 hours later. This gives a smaller first peak and a larger second wave compared to other capsule brands. With or without food. Swallow whole, or open and sprinkle onto cold soft food. Eat immediately. Do not crush or chew the pellets.

What helps
- Take in the morning: with 6–8 hour duration, late dosing risks disrupting sleep
- Wind-down routine from 9pm; avoid caffeine after midday
- If sleep is affected, try shifting dose 30 minutes earlier
DiscussSleep problems past 2–3 weeks should be raised at your next review.
What helps
- A mild wear-off effect is expected: the 70% extended component gives a gentler descent than 100% IR
- Plan lower-demand activities in the late afternoon
ExpectedWear-off with 30:70 tends to be more gradual than IR formulations.
What helps
- The gentler IR component means onset and offset tend to be smoother than 50:50 or 100% IR
- Note timing relative to your dose: useful information for your prescriber
- If wear-off is causing daily difficulties, discuss at your next review
DiscussIf rebound mood is affecting daily life, raise it at review.
What helps
- Eat before your dose: appetite suppression builds with the IR component kicking in
- Evening typically brings the best appetite return for your main meal
DiscussPersistent significant weight loss should be discussed at review.
What helps
- Expected pharmacological effect: monitored at every review
WatchChest pain, irregular heartbeat, or sudden dizziness: contact your prescriber promptly.
What helps
- Hydration is the most effective fix: aim for 6–8 glasses of water daily
- Paracetamol or ibuprofen are safe alongside methylphenidate
ExpectedUsually settles within the first 2 weeks.
What helps
