Questions about applying medication to the penis?
Hello Dr.
Lee, I would like to know what happens if a topical ointment (such as ophthalmic ointment) is applied to the glans or coronal sulcus and then left untreated.
Will the ointment be completely absorbed, or will there be residual material that needs to be removed by retracting the foreskin to prevent potential infections? Thank you!

Your question requires an understanding of the properties of ointments.
Water-based ointments are mostly absorbed, while oil-based ointments may leave some residue.
After applying medication to the foreskin, it is important to clean the area thoroughly with clean water daily before reapplying the medication.
Some residual medication is not harmful.

More Info
When it comes to applying medication, particularly ointments or creams, to sensitive areas such as the glans (the head of the penis) or the corona (the ridge of the glans), there are several important considerations regarding absorption, potential residue, and the risk of infection.
Firstly, the absorption of topical medications can vary significantly depending on the formulation and the specific active ingredients. For example, ointments and creams are designed to be absorbed through the skin, but they may not be completely absorbed. Some of the medication may remain on the surface of the skin, especially if a thick layer is applied. This residual medication can potentially lead to irritation or other adverse effects if not properly managed.
If you apply a medication like an eye ointment to the penis, it is crucial to consider that such products are not typically formulated for use on genital skin. The skin on the penis is sensitive and may react differently compared to other areas of the body. Therefore, using a product not intended for that area could lead to irritation, allergic reactions, or other complications.
After applying the ointment, if left unattended, there is a possibility that some of the medication will be absorbed, but there will likely be some residue left on the skin. This residue can trap moisture and bacteria, creating an environment conducive to infection, particularly if the area is not kept clean. Infections can arise from the buildup of bacteria, especially if the area is covered by the foreskin, which can create a warm, moist environment.
To minimize the risk of infection and ensure proper hygiene, it is advisable to gently clean the area after a certain period, especially if the medication is not specifically designed for use on the penis. If the medication is intended for a medical condition affecting the genital area, follow the healthcare provider's instructions regarding application and duration. If there are no specific instructions, it is generally a good practice to clean the area after a few hours to prevent any potential irritation or infection.
In summary, while some of the medication may be absorbed, it is likely that there will be residual product left on the skin. This residue can pose a risk of irritation or infection if not properly managed. It is essential to follow up with proper hygiene practices, including gently cleaning the area after a reasonable amount of time, to reduce the risk of complications. If you experience any unusual symptoms, such as redness, swelling, or discharge, it is important to consult a healthcare professional for further evaluation and guidance.
