A cold sore medicine will help to control the formation of the blisters. Cold sore occurrence is mainly due to the HSV-1 virus. The choices of medicines available for cold sores are not much.
So you have to choose very tactfully but for that you have to know more about the medicines.
Abreva, Benzocaine, Docosanol, Zovirax and Lidocaine are some of the medicines that are available for curing acute cold sore. Abreva, a FDA approved drug, has some fan following while for some patients this drug is completely useless.
This drug is available for a very small quantity of .07 ounce at a comparatively high price of $16 to $20. Zovirax can be crowned as an effective medicine for cold sore but the $120.00 for the 5g tube can be too much for many.
It shows the effects very quickly and soothes the tingling and pain that cold sore is coupled with.
The blisters will be cured if Zovirax is applied as soon as it appears. You can also consider Docosanol because it has proved to be effective for many people. It will ease the symptoms of the cold sore.
In the same way the medicines like Acetaminophen, Benzocaine, Ibuprofen and Lidocaine are also more or less effective agents that can cure the blisters of cold sore and lessen the pain.
