Concerta XL 18mg Prolonged-Release Tablets – Methylphenidate for ADHD

Concerta XL 18mg contains methylphenidate hydrochloride in a prolonged-release tablet taken once each morning. It is prescribed as part of a comprehensive treatment programme for attention deficit hyperactivity disorder (ADHD) in children aged 6 and over, adolescents and adults, alongside psychological, educational and social support.

18mg is the usual starting strength. Prescribers commonly begin here and review response and tolerability before deciding whether to move to 27mg, 36mg or higher. Starting low and adjusting upwards is the standard approach with methylphenidate, so an 18mg prescription is often the first step rather than the final dose.

Methylphenidate is a controlled medicine. HubPharm dispenses Concerta XL only against a valid prescription from a registered prescriber, verified by a licensed pharmacist before release.

FAQ

What is Concerta XL 18mg used for?

Concerta XL is used to treat ADHD in patients aged 6 and above as one part of a broader treatment programme. It requires regular review by the prescriber.

Is 18mg a starting dose or a maintenance dose?

For most patients 18mg is where treatment begins. Some remain on it long term, while others are moved up by their prescriber based on how they respond. Never change strength on your own.

Do I need a prescription for Concerta XL in Nigeria?

Yes. Methylphenidate is a controlled medicine and HubPharm supplies it only against a valid prescription, verified by our pharmacists. Your doctor can e-prescribe directly to us.

How much does Concerta XL 18mg cost in Nigeria?

Current pricing is shown above and reflects our sourcing at the time of listing. ADHD medicines are imported and prices move with supply and exchange rate. Contact our pharmacy team for current pricing, availability and HMO claim support.

When should Concerta XL 18mg be taken?

Once daily in the morning. Taking it later in the day makes difficulty sleeping more likely. Keep the timing consistent from day to day.

Can the tablet be crushed, chewed or split?

No. It must be swallowed whole with a drink. Crushing, chewing or splitting destroys the release mechanism and delivers the whole dose at once, which is unsafe. If swallowing tablets is difficult, tell your prescriber, as other ADHD formulations exist.

Why can the tablet shell be seen in the stool?

This is expected. The medicine is drawn out through the osmotic system and the empty outer shell passes through the bowel intact. It does not mean the dose was missed.

How long does one dose last?

The prolonged-release design is intended to give effect across roughly 12 hours from the morning dose. If cover is running out well before the end of the day, tell your prescriber rather than adding a second tablet.

What is the difference between Concerta XL 18mg and 36mg?

Same medicine, different strength. Treatment usually starts at 18mg and is adjusted upwards by the prescriber based on response and tolerability. Only a prescriber should move a patient between strengths.

What are the common side effects?

Reduced appetite, difficulty sleeping, headache, dry mouth, nausea, weight loss, and increases in heart rate and blood pressure. Anxiety, irritability or mood changes can also occur. Report anything troubling to your prescriber.

What monitoring is needed?

Prescribers usually track height, weight, appetite, blood pressure and heart rate at regular intervals, particularly in children and adolescents, with a periodic review of whether the medicine is still required.

Who should not take Concerta XL?

It is unsuitable for people with certain heart conditions, uncontrolled high blood pressure, glaucoma, hyperthyroidism, or a history of certain psychiatric conditions, and it must not be used with or close to monoamine oxidase inhibitors. Your prescriber assesses this before starting.

Can adults take Concerta XL 18mg?

Yes, where a clinician has assessed and diagnosed adult ADHD. Treatment should be initiated under specialist supervision.

How should Concerta XL be stored?

Store below 25°C in the original pack, out of the sight and reach of children, secured as a controlled medicine. Return unused tablets to a pharmacy for safe disposal. Never share this medicine with another person.
