Should I Continue Using Lidocaine Ointment for My Urological Issue?

Applying Lede Mei ointment resulted in the formation of white raised bumps?

Hello Doctor: Recently, I developed warts and purchased 5% Efudex cream to apply.
However, after using it for a while, I noticed that besides the area with warts, there are new white, blister-like bumps on the previously smooth glans, and these white bumps feel hard to the touch.
Should I continue using the Efudex cream in this condition, or should I stop using it first? Thank you, Doctor.

More Info

When it comes to using Lidocaine ointment (often referred to by its brand name, Lidoderm) for urological issues, particularly in the context of treating conditions like genital warts (cauliflower-like growths), it is essential to approach the situation with caution, especially given the new symptoms you are experiencing.

Firstly, Lidocaine is a local anesthetic that is commonly used to relieve pain and discomfort in various medical conditions. It works by blocking nerve signals in the body, which can provide temporary relief from pain. However, it is not an antiviral medication and does not treat the underlying cause of conditions like genital warts, which are typically caused by the human papillomavirus (HPV).

In your case, you mentioned that after applying the Lidocaine ointment, you noticed new white, hard bumps on the glans (the head of the penis) that resemble blisters. This is concerning for several reasons:
1. Potential Irritation or Allergic Reaction: The new bumps could be a result of irritation from the ointment itself. Some individuals may develop a sensitivity or allergic reaction to topical medications, leading to localized skin changes.
2. Infection or Other Dermatological Issues: The appearance of new lesions could indicate a secondary infection or another dermatological condition. It is crucial to differentiate between irritation from the medication and a potential worsening of the original condition or a new issue altogether.

3. Consultation with a Healthcare Provider: Given these new developments, it is highly advisable to stop using the Lidocaine ointment immediately and consult with a healthcare provider, preferably a urologist or a dermatologist. They can perform a thorough examination, assess the new symptoms, and determine the best course of action.
4. Alternative Treatments: If the bumps are indeed related to HPV or another underlying condition, your healthcare provider may recommend alternative treatments. Options for managing genital warts include topical treatments that are specifically antiviral (such as imiquimod or podofilox), cryotherapy, or other procedures depending on the severity and extent of the warts.

5. Monitoring Symptoms: While waiting for your appointment, monitor the new bumps closely. Take note of any changes in size, color, or sensation. If you experience increased pain, swelling, or any signs of infection (such as pus or fever), seek medical attention promptly.

In summary, it is not advisable to continue using Lidocaine ointment in light of the new symptoms you are experiencing. Stopping the medication and consulting with a healthcare professional is the best course of action to ensure proper diagnosis and treatment. Your health and safety should always come first, and a healthcare provider can give you the most appropriate advice tailored to your specific situation.
