Some symptom relief may be noticed within one to two hours; however, it may take up to two weeks for the full effects to be seen. Concerta tablets are an extended-release tablet that allow a more gradual release of methylphenidate, minimizing fluctuations in blood levels when compared with normal-release tablets.
Why does Concerta make me feel weird?
Concerta may cause dopamine levels to rise quickly when taken in very high doses, which can result in a euphoric feeling, or a high.
How long do Concerta side effects last?
For some, the drugs effects might last 10 hours, for others, only 6. Rather than a gradual return, ADHD symptoms can appear suddenly. When they do, theyll last an hour or so. When Concerta wears off and leaves your system, symptoms of ADHD may hit you even harder than before you took it.
Why do I feel sleepy after taking Concerta?
What causes the Concerta crash? Concerta releases methylphenidate into the bloodstream for around 12 hours. The body then starts to remove the drug from the system, leaving a chemical imbalance in the brain. This causes effects opposite to the stimulant nature of the drug, such as irritability and fatigue.
