Quillichew ER is a cherry-flavored, extended-release chewable tablet containing methylphenidate hydrochloride. It is FDA-approved for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients aged 6 years and older. Quillichew ER is designed with approximately 30% immediate-release and 70% extended-release methylphenidate, providing both rapid onset and sustained symptom control throughout the day. It is manufactured by Tris Pharma and marketed by Pfizer. Because it is a chewable tablet, Quillichew ER is particularly useful for patients who have difficulty swallowing pills.
Quillichew ER works by blocking the reuptake of norepinephrine and dopamine into presynaptic neurons in the brain. This increases the concentration of these neurotransmitters in the synaptic cleft, which helps improve attention, focus, and impulse control in patients with ADHD. The extended-release chewable formulation is taken once daily in the morning and provides symptom relief that lasts throughout the day.

Quillichew ER has a findability score of 45 out of 100, meaning it can be moderately difficult to locate in stock. As a Schedule II stimulant, Quillichew ER has been affected by the ongoing ADHD medication shortage driven by increased demand, DEA production quotas, and supply chain constraints. While the manufacturer Tris Pharma reports general availability, individual pharmacies may be out of stock at any given time. Using Medfinder can help you quickly identify pharmacies near you that currently have Quillichew ER in stock.
Quillichew ER can be prescribed by a variety of healthcare providers, including pediatricians, child and adolescent psychiatrists, general psychiatrists, family medicine physicians, primary care doctors, internists, and neurologists. Because it is a Schedule II controlled substance, it requires a written prescription and cannot be called in or refilled without a new prescription in most states. Telehealth providers may also prescribe Quillichew ER where permitted by state law.
Yes, Quillichew ER is classified as a Schedule II (CII) controlled substance by the DEA. This means it has a high potential for abuse and dependence.
