Hi Dear,
Welcome to HCM.
Understanding your concern.
As per your query
metallic taste in mouth occurs here is not because of Excedrin as Excedrin is a combination of
paracetamol, aspirin and caffeine and none of which is the cause for metallic taste in mouth.
Metallic taste in your mouth is mainly because of your underlying medical condition i.e
Diabetes which causes dryness of mouth as well and leads to poor immunity of oral cavity and make that susceptible to microbes and metallic taste.
I would suggest you not to panic about anything. Maintain hygiene of oral cavity. do brushing twice a day along with flossing.
Use antimicrobial mouth wash such as
Listerine.
Do warm saline gargles on daily basis.
Take diet rich in citrus fruits such as orange, lemon and add two drops on tongue to simulate taste.
Chew sugarless candies.
Visit
dentist if this condition keeps on persisting for more than a week.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
