Aciclovir Dosage and Administration Guidelines
When to Start Taking Aciclovir
The effectiveness of aciclovir depends significantly on when treatment begins. Start taking aciclovir as soon as you notice the first warning signs of a cold sore, such as tingling, itching, or burning around the lips. Beginning treatment within the first 24-48 hours of symptom onset may help reduce the severity and shorten the duration of the outbreak.
Aciclovir Tablet Dosage
For cold sores, the typical aciclovir tablet dosage is 200mg taken five times daily for five days. EverydayMeds offers aciclovir 400mg tablets, which may be prescribed as 400mg twice daily as an alternative regimen. Take tablets with a full glass of water and space doses evenly throughout the day. You can take aciclovir with or without food, though taking it with food may help reduce stomach upset if you experience any digestive discomfort.
Aciclovir Cream Application
If using aciclovir 5% cream, apply a thin layer to the affected area every 4 hours, approximately five times daily. Wash your hands thoroughly before and after application to prevent spreading the infection. Avoid touching the cold sore with your fingers when possible. The cream should be continued for 5 days, or until the lesion has healed if this occurs sooner.
Important Usage Considerations
Complete the full prescribed course of aciclovir, even if your symptoms improve before finishing the medication. Stopping treatment early may allow the virus to remain active and potentially lead to prolonged symptoms. If you miss a dose, take it as soon as you remember, unless it's nearly time for your next dose. Never double up on doses to compensate for missed tablets.
Treatment Options Available
EverydayMeds provides several antiviral options for cold sore treatment, including aciclovir tablets and cream, as well as valaciclovir tablets for those requiring alternative treatment approaches. These prescription medications are available through our online consultation service, allowing convenient access to effective cold sore management without visiting a GP surgery.
