Manufacturing and expiry dates vary by batch and are not published online to avoid confusion or the risk of incorrect information. However, each batch undergoes strict quality checks, and products are dispatched only after confirming they are well within their valid expiry period.

The ointment you applied contains mupirocin, which is a topical antibiotic helpful for treating superficial bacterial infections. While it may provide some initial relief, pus around the penile ring can indicate a deeper bacterial infection, a fungal infection, or another underlying issue that a topical antibiotic alone might not fully cure. Please keep the area clean by gently washing with warm water and drying it thoroughly, avoiding harsh soaps. I highly recommend consulting a doctor or urologist for a proper evaluation. They can identify the exact cause and prescribe the correct treatment, which may include specific oral antibiotics or antifungal creams.
