Does Tirzepatide Cause Insomnia?

Tirzepatide can cause insomnia as a side effect, though it affects only 3-5% of users. Sleep disturbances typically occur during the initial weeks of treatment as your body adjusts to the medication's effects on blood sugar regulation and gastric emptying. The sleep disruption often stems from gastrointestinal symptoms like nausea or changes in eating patterns rather than direct neurological effects. Most patients find that sleep issues improve after 4-6 weeks once their system adapts to the medication. If you experience persistent sleep problems while taking tirzepatide, consult your healthcare provider about strategies to improve sleep quality while continuing treatment.
