I have herpes type 1. Is it safe to use abreva?

I have herpes type 1. Is it safe to use abreva?

Yes but Ice helps: The best remedy for mitigating or abating cold sore symptoms is to apply ice directly to the spots as soon as you have the prodromal symptoms (itching, tingly sensation or pain). Applying ice cubes for 10 to 15 minutes at a time 2 or 3 times a day for 1 or 2 days totally stops the sores from developing or progressing into cratered ulcers. Nothing in the pharmacies matches this. Good luck! ...Read more

I keep getting cold sores back to back I saw one coming up so I used the abreva it went down n couple days later it came bk up what is causing that?

Herpes virus: Cold sores are viral infections and the virus "hides" in the nerves close to where the ulcer is. That is why they tend to come back in the same location. The best treatment involves antiviral meds. There is a topical application called viroxin that kills the virus and very effective at the early signs. However if your immune system is low, they come right back. ...Read more

What is the difference between zovirax (acyclovir) and abreva?

One of them works!: To start, Zovirax (acyclovir) works and Abreva (docosanol) doesn't. Acyclovir is proved to be effective against HSV, when taken by mouth. Docosanol slightly inhibits the virus in the lab, but research shows no effect on improved symptoms or faster healing. Even acyclovir cream doesn't work well -- much more ffective by mouth -- but it's for sure better than docosanol. ...Read more

Had coldsore & put Abreva on right away. It was healed over in 9days but has left a bright red circular spot another 10days. Is it actually healed?

Had coldsore & put Abreva on right away. It was healed over in 9days but has left a bright red circular spot another 10days. Is it actually healed?

It's healed, but...: If the red area is intact (no open sore or scab) your outbreak has healed. It can take a few weeks for redness to fade. FYI, Abreva is ineffective; your cold sore probably didn't heal any faster than it would anyway. Speak w/ your doctor about prescription for valacyclovir (Valtrex®) to have on hand. One dose by mouth, as soon as an outbreak starts, is very effective, a lot faster than 9 days. ...Read more

Is abreva good for genital herpes?

Not so good: Docosanol (Abreva) has little if any effect against herpes outbreaks. It somewhat inhibits the virus in the lab, but has little benefit in shortening outbreaks. (The same is true for all creams or ointments, such as acyclovir or penciclovir, even though these are far more potent than docosanol against the virus.) Effective treatment requires oral therapy, e.g. valacyclovir or acyclovir. ...Read more
