Pain Under Tongue After Taking Medication: Causes and Remedies - Otolaryngology

Pain under the tongue caused by medication?


Hello, doctor.
I'm not very good at swallowing pills.
Yesterday, when I took my medication, I opened the antibiotic capsule and only took the powder.
When the powder touched the area under my tongue, I felt a significant stinging sensation.
When I took the second antibiotic, I poured it onto my tongue, and some of the powder fell under my tongue, causing stinging sensations both above and below my tongue.
This morning, I woke up still feeling pain under my tongue.
When I looked in the mirror, I noticed a thin white membrane under my tongue.
When I kept poking at the membrane with my tongue, it would come off, but some of it still remains.
Because the powder hurt so much when it touched my tongue, I tried swallowing the capsule today, and I'm happy that I overcame that obstacle and managed to swallow it.
I'm also taking traditional Chinese medicine to help my body.
Today, when I took the Chinese medicine, the powder also fell under my tongue, and it was extremely painful.
I think it's because that area is already injured.
It was really scary to be hurt by the capsule powder for the first time.
Doctor, will the pain under my tongue heal gradually? Thank you, doctor.

Hello, it is possible that the tongue ulcer is caused by irritation from the medication powder, which will usually improve gradually.
However, if there is no improvement after one week, it is advisable to seek medical evaluation.
Wishing you safety and health.
Sincerely, Dr.

More Info


The pain you are experiencing under your tongue after taking medication is likely due to irritation or injury caused by the powdered form of the medication coming into contact with the sensitive tissues in that area. The sublingual area, which is the space under the tongue, is rich in blood vessels and nerve endings, making it particularly sensitive. When powdered medication is placed there, it can cause localized irritation, leading to pain and discomfort.

The presence of a white film under your tongue could indicate a few things. It might be a result of irritation or a mild inflammatory response to the medication. In some cases, a white coating can also be associated with oral thrush, a fungal infection caused by an overgrowth of Candida, especially if you have been taking antibiotics, which can disrupt the natural balance of flora in your mouth. However, if the white film is easily removable and not associated with other symptoms like itching or a burning sensation, it is more likely related to irritation rather than an infection.

Here are some recommendations for managing your symptoms and promoting healing:
1. Avoid Irritants: Try to avoid placing any more powdered medications under your tongue until the area has healed. If you need to take medication, consider swallowing capsules whole or using liquid formulations if available.

2. Maintain Oral Hygiene: Gently rinse your mouth with warm salt water several times a day. This can help reduce inflammation and promote healing. Avoid mouthwashes that contain alcohol, as they can further irritate the area.

3. Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain if necessary. Be sure to follow the recommended dosages and consult with a healthcare provider if you have any concerns.

4. Monitor Symptoms: Keep an eye on the area for any changes. If the pain persists beyond a few days, worsens, or if you develop additional symptoms such as fever, swelling, or difficulty swallowing, it would be wise to consult a healthcare professional for further evaluation.

5. Dietary Adjustments: Stick to soft, bland foods that are less likely to irritate your mouth. Avoid spicy, acidic, or crunchy foods until the area has healed.

6. Hydration: Ensure you stay well-hydrated, as this can help maintain moisture in your mouth and support healing.

In most cases, the irritation should gradually improve over a few days to a week, as long as you avoid further irritation and maintain good oral hygiene. If you find that the pain does not subside or if you have concerns about the white film or any other symptoms, it is advisable to seek medical attention. A healthcare professional can provide a thorough examination and determine if any specific treatment is necessary, especially if there is a concern about an infection or other underlying issues.
In summary, while the pain under your tongue is likely a result of irritation from the powdered medication, it should heal with proper care. If symptoms persist or worsen, do not hesitate to consult a healthcare provider for further guidance.
