Aciclovir Dosage and Administration Instructions
Standard Aciclovir Dosage for Cold Sores
For treating cold sores, the typical aciclovir dosage is 200mg taken five times daily for five days. Some patients may be prescribed 400mg three times daily as an alternative regimen. The key to effective treatment is starting aciclovir as soon as you notice the first signs of a cold sore developing, such as tingling, itching, or burning sensations around the lips.
When and How to Take Aciclovir Tablets
Take aciclovir tablets with or without food, swallowing them whole with water. Space your doses evenly throughout the day - for five daily doses, aim for every 4 hours during waking hours. You don't need to wake during the night for doses. Start treatment immediately when you feel the first symptoms, as early intervention significantly improves effectiveness. EverydayMeds stocks aciclovir 400mg tablets for patients requiring this dosage strength.
Treatment Duration and Compliance
Complete the full prescribed course of aciclovir, typically 5 days, even if your cold sore symptoms improve earlier. This ensures the virus is properly suppressed and may help prevent the outbreak from returning. If you miss a dose, take it as soon as you remember, then continue with your regular schedule. Don't double up doses to make up for missed ones.
Aciclovir Cream Application
EverydayMeds also offers aciclovir 5% cream for topical treatment. Apply a small amount to the affected area five times daily for 4 days, starting at the first sign of symptoms. Wash your hands before and after application to prevent spreading the virus to other areas.
Who Should Avoid Aciclovir
Most adults can safely use aciclovir, but inform your healthcare provider if you have kidney problems, are pregnant, breastfeeding, or taking other medications. Some people may experience mild side effects such as headaches or nausea. EverydayMeds' online consultation service can help determine if aciclovir treatment is suitable for your specific situation.
