When Do ADHD Medications Start Working? 

One of the most common questions people ask when starting ADHD treatment is, “When do ADHD medications start working?” The ADHD medication onset can vary depending on the type of medication, individual response, and other factors such as dosage and administration method. 

Stimulant Medications 

For stimulant medications like methylphenidate (Ritalin) and amphetamines (Adderall), the effects are typically felt within 30 to 60 minutes of taking the medication. These medications work quickly by increasing dopamine and norepinephrine levels in the brain, improving focus, attention, and impulse control almost immediately. Time to effect can vary slightly depending on whether the medication is in immediate-release or extended-release form. Immediate-release stimulants usually show effects faster than their extended-release counterparts. 

Non-stimulant Medications 

Non-stimulant medications like atomoxetine (Strattera) and guanfacine (Intuniv) tend to have a slower onset. These medications work by regulating norepinephrine, but they typically take several days to weeks before noticeable improvements in focus and behaviour are observed. Because of this gradual action, non-stimulants may be a better option for individuals who prefer a more steady approach or have experienced side effects with stimulants. 

In conclusion, the ADHD medication onset varies depending on the type of medication used. The treatment response of stimulants and non-stimulants vary. Stimulants work quickly, while non-stimulants may take longer but provide steady, long-lasting results.
