Motion Sickness - Car Rides

Users report new or worsened motion sickness during car rides after starting tirzepatide, along with vertigo and ear symptoms. One person linked these to possible Eustachian tube dysfunction from fat loss around the ear canals, which can affect balance and inner-ear function. Research cited shows weight loss can trigger ETD and that ETD can produce vertigo, though the connection to motion sickness remains unclear. The Epley maneuver helped resolve one case of vertigo.

• Motion sickness appeared or intensified after starting tirzepatide for multiple users
• Weight loss may remove fatty tissue supporting Eustachian tubes, leaving them open
• Open Eustachian tubes can transmit sounds directly to the inner ear and cause pain or vertigo
• ETD is documented to produce vertigo but its effect on motion sickness is not confirmed
• The Epley maneuver resolved first-time vertigo for one user without medical intervention

Whether the motion-sickness effect will fade over time or remain permanent

Nothing here is advice.
