It has been acknowledged that over 50 million people suffer from cold sore during any given year. A fever blister sticks around for few weeks and it is usually accompanied by discomfort and feelings of embarrassment. Definitely, when you think of getting rid of cold sore some questions will arise in your mind like what is the best medicine for cold sores?
Besides home remedies for fever blisters, there are some medications, which are helpful in effectively healing this awful virus. You will not be completely cured using these medications because the cold sore virus is incurable at the moment. The two best cold sore medications that work are as follows:
- Novartis Company has produced Denavir cream, used to cure these sores. It is a FDA approved medication. You will need to apply it on effected area every 2 hours, for 4 days. You will need to follow some precautionary measures while applying it on the affected area as the herpes virus can spread easily. Put the cream on your finger, apply it to the blister and then wash your hands immediately so that you do not spread the virus to other parts of your body or other people. It effectively reduces the pain caused by cold mouth sore. Denavir cream has an active ingredient peniciclover, which helps in reducing the potency of the virus and therefore your sore will stick around for less time. Once you feel itching or tingling, apply the cream as soon as possible. It might cause some side effects in certain people like skin flushing, skin dryness or allergy.
- Another FDA-approved prescription medication is Zovirax. In order to fight with herpes simplex virus, you will need to take 4-6 tablets of Zovirax, a day. You can also use Zovirax cream 5 times a day, for 5 days, by following the same precautions as you did for Denavir cream. It will not only help you to fight against cold mouth sores, but also be helpful in healing as well.
