Doxepin can cause drowsiness, so avoid driving or operating machinery until you know how it affects you. Drink plenty of fluids to prevent constipation, a common side effect.
Common Side Effects
Drowsiness: This is frequently reported. Consider taking your dose before bed. Dry mouth: Sip water regularly. Constipation: Increase fiber intake and hydration. Blurred vision: Avoid tasks requiring sharp vision until the effect subsides. These usually lessen with continued use.
Less Common, but Important Side Effects
Weight gain: Maintain a healthy diet and exercise routine. Orthostatic hypotension (dizziness upon standing): Rise slowly from a seated or lying position. Increased appetite: Be mindful of your caloric intake. Consult your doctor if you experience unusual changes in your weight or appetite.
Precautions
Alcohol interaction: Avoid alcohol consumption while taking doxepin, as it can intensify drowsiness. Interactions with other medications: Inform your doctor of all medications you are currently taking, including over-the-counter drugs and herbal supplements. This is vital to prevent potentially harmful interactions. Pregnancy and breastfeeding: Discuss doxepin use with your doctor if you are pregnant, breastfeeding, or plan to become pregnant. Suicidal thoughts: Doxepin may worsen suicidal thoughts in certain individuals. Monitor your mood closely and seek immediate medical help if you experience any such thoughts.
When to Contact Your Doctor
Contact your healthcare provider immediately if you experience severe side effects, such as difficulty breathing, chest pain, seizures, or allergic reactions (rash, swelling, itching).
