I got a cold sore last week and took the 2grams twice a day for one day. It turned out not being that bad. Then today I woke up (4 days later) and felt that tingling feeling again on my lips so I took 2 grams of Valtrex right away. But what I noticed was that my whole top lip was basically covered and then part of my bottom lip was covered too!!! Then by 4 o'clock this afternoon I noticed the other side of my lip was starting to tingle!!! So basically all of lips are covered in cold sores and I'm really upset about this and NEVER have had it like this. Can I take more then the 2 grams twice a day that is recommended since this case of cold sores are so bad?
How Much Valtrex Can I Take For My Cold Sores if the Prescribed 2grams Twice a Day is Not Working?

No, you should not exceed the recommended dosage of 2 grams twice daily for 1 day taken 12 hours apart. Therapy should be initiated at the earliest symptom of a cold sore (e.g., tingling, itching, or burning).
You should see your doctor again. If you get reoccurring cold sores you may need to take a preventative or maintenance dose of antiviral medication.
