Your friend has been prescribed Zosert (sertraline) for mood or anxiety support, Etizola (etizolam) for short-term anxiety or sleep relief, and Histac (ranitidine) to protect her stomach from acidity. Sertraline is typically taken long-term (several months), while etizolam is usually for short-term use. The duration depends on her doctor's advice. Common side effects can include mild nausea, drowsiness, or dry mouth, which often improve as her body adjusts. Please reassure her that these are commonly prescribed together to help her feel better safely. She should consult her doctor before making any changes.
