How to Manage Dizziness
Most episodes of dizziness while taking Mounjaro® or Wegovy® are mild and can be managed with the following steps:
Hydrate immediately: Drink plenty of fluids, such as water or herbal teas, as dehydration is a frequent cause of lightheadedness.
Prioritise safety: If you feel dizzy, lie down immediately until the sensation passes to prevent falls.
Move with caution: When getting up from a sitting or lying position, move carefully and slowly to allow your blood pressure to adjust.
Rest: Ensure you are getting plenty of sleep and allowing your body to recover.
Avoid stimulants and toxins: Stay away from coffee, cigarettes, and alcohol, as these can exacerbate dizzy spells.
When to Contact Your GP or Call 111
While dizziness is a known side effect, certain symptoms may indicate a more serious underlying issue. Contact your GP or call 111 if you experience dizziness alongside:
Difficulty hearing or speaking clearly.
Persistent ringing in your ears (tinnitus).
Changes in your vision, such as blurring or double vision.
Any instance where you lose consciousness or faint.
(Always inform the healthcare provider that you are currently using Mounjaro® or Wegovy® for weight management.)
When to Seek Urgent Medical Help
Call 999 or go to your nearest A&E immediately if you experience dizziness accompanied by:
Numbness or weakness in your face, arms, or legs.
