Escitalopram is a prescription medication commonly used to treat depression and anxiety disorders. It belongs to a class of drugs known as selective serotonin reuptake inhibitors (SSRIs), which work by increasing the levels of serotonin, a neurotransmitter that helps regulate mood. Patients typically take Escitalopram once daily, and it may take several weeks to notice its full effects. Common side effects can include nausea, fatigue, and changes in sleep patterns. It is important for individuals to consult their healthcare provider for proper dosage and to discuss any potential interactions with other medications.
