Short answer
Follow your prescribing physician’s directions and the pharmacy label. The typical cold sore course is 2 g at the first sign, then 2 g again 12 hours later. With 1 g tablets, each dose is two tablets. Your physician may change this dose based on your health, especially kidney function.
Your prescribing physician and pharmacy label set your dose. The typical directions for this product are 2 g at the first sign of a cold sore, followed by another 2 g dose 12 hours later. Each 2 g dose uses two 1 g tablets. This is usually a one-day course, not a daily ongoing schedule.
Do not take extra doses or continue for more days unless your physician tells you to. If the label differs from the directions on this page, ask your pharmacist or prescriber to confirm the plan before taking it. Do not use someone else’s prescription.
A licensed physician in your state decides whether this treatment and dose are appropriate. Tell them about kidney disease, dialysis, pregnancy, breastfeeding, and all medicines you take. People with reduced kidney function may need a different dose or schedule. Ask for clear instructions if you are unsure how many tablets to take or when to take the second dose.
