Most of the side effects of escitalopram oxalate will disappear with the treatment time, exactly how long to eliminate there is no exact time, it varies from person to person, some days, some weeks, and some also some side effects will persist. Escitalopram oxalate is a commonly used antidepressant in clinical practice, and its mechanism of action is to block the reuptake of pentazocine in the synaptic gap. Its side effects are theoretically non-therapeutic due to the enhanced function of pentazocine, such as affecting sleep centers leading to insomnia, affecting gastrointestinal pentazocine leading to diarrhea, and affecting dopamine release leading to emotional apathy and cognitive delays. Most adverse effects occur rapidly with the use of the drug, especially when the drug is dosed too quickly, and many of the adverse effects show a dose and time correlation, appearing as the dose increases, persisting until tolerance develops, and disappearing over time. The exact time to disappear varies from person to person, and may be as short as a few days, as long as a few weeks, or even persist for a long period of time. If side effects persist for more than a few weeks, or if symptoms are severe, a change in medication may be considered, or the appropriate medication may be given under the direction of a physician to manage the side effects.
