How do I manage a swollen tongue and an ulcer in the mouth?

Hello,

Welcome to icliniq.com.

I understand your concern.

Based on what you have described, the swollen, rubbery-feeling tongue, chalky sensation, and mouth ulcer are likely a result of irritation from overuse of alcohol-based mouthwash and menthol-rich products like cough drops.

These can dry out and inflame the soft tissues of the mouth, especially with repeated or prolonged exposure. The ulcer at the corner of the mouth is a form of angular cheilitis, which can develop from irritation, dryness, or even mild infection.

The drowsiness you experienced after using Benzydamine hydrochloride is uncommon but not impossible. While Benzydamine can cause mild systemic effects if absorbed in significant amounts (especially if swallowed), it is more likely that the sensation triggers a panic response, particularly if you are sensitive due to your ADHD (attention deficit hyperactivity disorder) or stimulant medication (Lisdexamfetamine), which can heighten anxiety in some people.

I would suggest the following:

• Stop using the alcohol-based mouthwash and cough drops for now to let your mouth heal.

• Switch to a non-alcohol, gentle mouthwash (like saltwater rinses or one with aloe vera or baking soda).

• Use a topical soothing gel like Triamcinolone dental paste or an antiseptic mouth gel that is alcohol-free.

• Keep hydrated and avoid spicy or acidic foods.

• For the ulcer at the mouth corner, applying a mild antifungal or antibacterial cream (like Clotrimazole or Mupirocin) will help, especially if there is cracking or crusting.

If the tongue swelling worsens, you develop difficulty breathing, or symptoms last more than a few days, then testing should be done urgently to rule out an allergic reaction, infection, or vitamin deficiencies (like B12 or iron).

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
