Penvir 250 Tablet is an antiviral medicine used to treat infections caused by the herpes virus, including cold sores (herpes labialis), genital herpes, and shingles (herpes zoster). It helps the sores heal faster and reduces pain and discomfort during an outbreak.
It contains famciclovir, which stops the herpes virus from multiplying in the body, helping your immune system clear the infection. Take the tablet with or without food, preferably at the same time each day. Complete the full course as prescribed, even if you start feeling better, to prevent the infection from returning.
Starting treatment as soon as symptoms appear, such as tingling or itching before blisters form, helps the medicine work best. Keep the affected area clean and dry, avoid touching or scratching the sores, and drink plenty of water through the day to support your kidneys while on this medicine.
Before taking this medicine, tell your doctor if you have kidney problems, as your dose may need to be adjusted. Inform your doctor if you are pregnant or breastfeeding. Contact your doctor if the sores do not improve, spread further, or if you develop a high fever alongside the outbreak.
