Usage

• Take it as prescribed: Spectra Capsule contains Doxepin and should be taken at the dose and frequency recommended by your doctor. The schedule depends on the condition being treated and the capsule strength.

• Swallow with water: Take the capsule as directed, with or without food. Avoid changing the dose on your own.

Uses

Spectra Capsule contains Doxepin, a tricyclic antidepressant that affects certain brain chemicals involved in mood and emotional balance. Its uses depend on the prescribed strength and formulation.

• Depression management: Helps relieve symptoms of depression, including persistent low mood and reduced interest in daily activities.

• Anxiety management: May help reduce anxiety symptoms, including excessive worry, nervousness, and emotional tension.

• Improves emotional well-being: By influencing serotonin and norepinephrine activity, doxepin may gradually improve mood and emotional stability.

• Supports better sleep: Its calming and sedating effects may help improve sleep when sleep difficulties accompany depression or anxiety.

Note: Use Spectra Capsule only under medical supervision. Inform your doctor about heart conditions, glaucoma, urinary difficulties, or other medicines you take. Avoid driving until you know how the medicine affects you. Seek prompt medical attention for severe mood changes, thoughts of self-harm, fainting, or an irregular heartbeat.
