Furuncles: Risks of Self-Treatment and Over-the-Counter Remedies - Dermatology

Suspected furuncle?


Hello, doctor.
My husband seems to have developed a furuncle on his nostril.
He initially thought it was a pimple and tried to squeeze it himself, but I feel that the wound is a bit too large.
After four to five days, I noticed that the area around the wound appears to be indented and has not healed.
I would like to know what potential side effects could occur if we purchase an over-the-counter ointment for furuncles, assuming it is not the correct treatment.
Thank you for your response.

When the medication is not appropriate for the condition, it may sometimes be ineffective, and at other times, it may even worsen the condition.

More Info


Furuncles, commonly known as boils, are painful, pus-filled bumps that form under the skin due to bacterial infection, often caused by Staphylococcus aureus. They can occur anywhere on the body but are most commonly found in areas where hair follicles are present, such as the face, neck, armpits, and buttocks. Understanding the risks associated with self-treatment and the use of over-the-counter (OTC) remedies is crucial for effective management and prevention of complications.

When your husband attempted to pop what he thought was a pimple, he may have inadvertently introduced bacteria deeper into the skin, leading to a more severe infection. The fact that the wound has not healed after several days and appears to be indented suggests that it may be developing into a more serious condition, such as an abscess. This situation warrants careful consideration before proceeding with self-treatment.

Using OTC remedies without proper diagnosis can lead to several risks and complications:
1. Misdiagnosis: If the lesion is not a simple boil but rather a more complex skin infection or another dermatological condition, applying the wrong treatment can exacerbate the issue. For instance, if it is a carbuncle (a cluster of boils) or a skin abscess, it may require drainage and possibly antibiotics.

2. Delayed Healing: OTC treatments may not be effective for deeper infections. If the boil is not treated appropriately, it could lead to prolonged healing times, increasing the risk of scarring or further complications.

3. Increased Risk of Infection: Self-treatment can lead to improper cleaning and care of the wound, which may introduce more bacteria and worsen the infection. Additionally, if the boil is not fully drained, pus can accumulate, leading to an abscess that may require surgical intervention.

4. Allergic Reactions: Some OTC medications or topical treatments may cause allergic reactions or skin irritations. If your husband applies a product that contains ingredients he is sensitive to, it could lead to further complications, such as dermatitis or worsening of the infection.

5. Systemic Infection: In severe cases, untreated or improperly treated boils can lead to systemic infections, such as cellulitis or sepsis, which can be life-threatening. Symptoms of systemic infection include fever, chills, and increased pain or swelling in the affected area.

Given these risks, it is advisable to seek professional medical evaluation rather than relying solely on OTC treatments. A healthcare provider can accurately diagnose the condition and recommend appropriate treatment, which may include:
- Incision and Drainage: If the boil is large or has formed an abscess, a doctor may need to perform a minor surgical procedure to drain the pus and relieve pressure.

- Antibiotics: If there is evidence of a bacterial infection, especially if it is spreading or if the patient has a weakened immune system, antibiotics may be necessary.

- Proper Wound Care: A healthcare provider can give specific instructions on how to care for the wound to promote healing and prevent further infection.

In conclusion, while it may be tempting to treat a boil at home with OTC remedies, the risks associated with self-treatment can outweigh the benefits. It is essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan. This approach not only ensures effective management of the current condition but also helps prevent potential complications in the future.
