The working of Modalert in boosting wakefulness is not completely understood. However, it is assumed that it has an action similar to amphetamine and methylphenidate. It comes under the drug called alpha-adrenergic receptor inhibitor, the medicine that sticks to dopamine and inhibits the reuptake of certain brain chemicals. In short, Modalert promotes wakefulness by potentiating dopamine levels in the central nervous system.
These are a few possible side effects of Modalert. They usually subside; if they persist, call your doctor right away.
I recently switched to Modalert from Provigil and found both of them equally effective. I bought Modalert pills online from this store. Nice packaging. Prompt service. User-friendly executives.
