Vicks First Defence - holding off rather than killing a cold?

[Wonderbug81]

Has anyone else could when using First Defence that it holds off a cold but it comes back when you stop?

I took it for 2 days after my symptoms went away, as directed so it's not a case of not having taken it long enough? Felt totally fine while taking it but within a day my symptoms are back.

A shame as it had worked before. I don't use it often but wondering if my body has become immune to it?!

Nothing can kill a cold.

Your body hasn't become immune to Vicks.

Perhaps this time the virus was worse than last time, or maybe you caught a second virus. Every virus is a little different.

I found this too. It was very useful once when I needed to keep a cold from hitting before a medical procedure but unless you persist for more than a week it will still get you in my experience!

No, you've not become immune. If works by increasing the acidity of the nasal passages which makes it harder for the virus to reproduce so it isn't something you can become immune to.

My guess is that for the 2 days after symptoms went it successfully slowed virus reproduction but didn't quite get rid of it totally.

Then when you stopped using it, the remaining virus took advantage of the "better" conditions for reproduction and started to take hold again. I think you can restart using the spray.

Thanks this is really helpful.

@verycloakanddaggers I didn't think anything could kill a cold but they claim in their marketing that it helps to helps to trap, inactivate and remove cold viruses before a full blown cold develops.'
