When it comes to managing ADHD, one key question many people have is, “How long do ADHD medications last?” The ADHD medication duration depends on the type of medication and its formulation, with variations between short-acting vs long-acting options playing a significant role in how long the effects last. 

Short-acting stimulant medications like methylphenidate (Ritalin) and amphetamine salts (Adderall) generally start working within 30 to 60 minutes and provide symptom relief for around 4 to 6 hours. These medications are ideal for individuals who need a quick, focused boost for short tasks or during specific time frames, such as studying or work sessions. However, they require more frequent dosing throughout the day to maintain symptom control. 

Long-acting stimulant medications, such as extended-release formulations like Concerta (methylphenidate) and Vyvanse (lisdexamfetamine), offer longer-lasting effects, typically lasting 8 to 12 hours. These medications are designed to provide continuous symptom relief throughout the day, making them convenient for people who need consistent focus from morning until evening. The extended duration of these medications can help reduce the need for multiple doses, offering convenience for individuals with busy schedules.
