Duzela 20 Capsule DR contains Duloxetine (20mg) in a delayed-release formulation, used to treat conditions such as depression, generalized anxiety disorder, neuropathic pain, and fibromyalgia. Duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI) that works by balancing chemicals in the brain, helping to improve mood, relieve anxiety, and reduce pain signals. Common side effects include nausea, dry mouth, drowsiness, and dizziness. The delayed-release (DR) formulation ensures that the medication is gradually absorbed, reducing the risk of gastrointestinal irritation. It is typically taken once daily, with or without food.
