I've suffered from sinus issues for many years now. My right nostril often closes up and causes me all sorts of issues - including the horrid sinus headaches. I have had sinus issues so often, I am used to it.  I use an array of nasal decongestants, and I always have a bottle of Olbas oil nearby, so when I was invited to review the new product Serenz, I was excited to give it a go.

Serenz is the first allergy treatment to use carbon dioxide to relieve your nasal allergy symptoms. It's clinically proven to work quickly against nasal allergy symptoms, without causing drowsiness.

Serenz can help with symptoms of nasal allergies:

• Nasal congestion
• Itchy, runny nose
• Sneezing

It's a handheld device and designed to relieve congestion, itching and sneezing associated with hayfever - anything to do with nasal allergy symptoms. Perfect for someone like me.  It's quite a large device (twice the size of your normal nasal sprays), and it's very simple and easy to use: You insert it into the nostril, the on/off button is pressed for 10-seconds and you should either breathe through your mouth during this time or hold your breath - and can be used up to 6-times per day.

I've used it a few days now, and although, it definitely feels a bit alien (different to normal nasal sprays - it makes your eyes water a little) I found it is working quite well for me, my nose is cleared quickly and allows me to be more comfortable. I am definitely encouraged to continue using it.

Available only at Weldricks online and with an RRP of £19.90, Serenz is a good alternative.

Serenz is not suitable for women who are pregnant or breastfeeding.
