Can Trulicity (dulaglutide) cause a metallic taste?
Trulicity can cause changes in taste, including a metallic taste, as a possible side effect. Taste changes fall under common gastrointestinal and sensory side effects that some people report with GLP-1 medicines like dulaglutide.
What other side effects often come with a metallic taste?
When taste changes happen with Trulicity, people often also notice oral or stomach-related effects such as nausea or indigestion, which can make flavors feel “off” or leave an unusual aftertaste.
When should you call a clinician about taste changes?
Check in with a clinician if the metallic taste is severe, doesn’t go away, or comes with warning symptoms such as trouble swallowing, facial or tongue swelling, or breathing problems. Those can suggest a reaction that needs urgent care.
What might be causing a metallic taste besides Trulicity?
A metallic taste can also come from other common causes, including:
- New medications or dose changes
- Dental or gum issues
- Acid reflux or heartburn
- Recent illness or sinus problems
- Vitamin or mineral changes (for example, zinc)
If you started Trulicity recently, the timing can help point to the medication.
How long does a metallic taste last?
For many people, these taste changes improve as the body adjusts after starting or increasing the dose. If symptoms persist beyond a few weeks or worsen, it’s worth discussing dose timing, supportive care, or alternative treatments with your prescriber.
