With so many cold sore remedies it is hard to choose the right one, with claims being made about how long the infection takes to heal you can be forgiven for how confusing you might find it searching for a solution. In my opinion and from what I have read and seen the best remedies are those that contain the virus, stop it from reappearing and shorten the lifespan of a cold sore, the only cold sore remedy that does this is Abreva Remedy.
Abreva Cold Sore Remedies
This is a relatively new medicine that has been developed by Glaxosmithkline who also bought Zovirax into the market. Abreva has an active active ingredient called Docanosol. Docanosol has been proven to prevent the replication of the herpes virus in healthy cells by making them momentarily herpes proof. Docanosol has been clinically proven to shorten the lifespan of a cold sore and its healing time.
How Does Abreva Work?
Docanosol acts as a barrier to the infection to the healthy cells, this means that as soon as you feel the tingling stage you can apply the Abreva and the cells surrounding the virus become like a impenetrable membrane that cannot be breached. It prevents the Herpes Simplex virus from entering the healthy cells and it is confined to that particular area sort of like a viral envelope. Viral replication falls and the amount of infection also decreases. The benefits of applying Abreva early are you contain the disease and therefore it cannot grow and replicate thus shortening the timespan of the actual cold sore.
How Does Abreva Compare to other Cold Sore Remedies?
The alternative to Abreva is Denavir and the difference between the two is that Denavir is a antiviral which actually kills the virus, wheras Abreva is like a envelope that contains the disease. In my opinion Abreva is better, if you are able to contain the disease and stop it from replicating the then the lifespan of the sore is a few days. Denavir on the other hand is a antiviral which only kills the virus but does not stop it from growing. The benefits of catching the cold sore early is it heals sooner.
To conclude I think that there maybe room to use both the treatments, Abreva is a prescription based medication whereas Denavir is over the counter. If you are able to catch the virus early then I would for sure use Abreva, however if for some reason you are unable to catch the infection early then you may wish to use a combination of Abreva and Denavir. This may sound controversial but from what I have experienced and researched this works quite well.
