I bought these products with my own money. No-one gave them to me and no-one is paying me to write this.
I have seasonal allergies. This year I started allergy season with Reactine and have been coping well. Until that first pack was used and I had to replace it. I went to a supermarket and bought their own brand of antihistamine. It simply did not work. Neither of these medications requires a prescription in Canada.
Today I took a Reactine tablet and within twenty minutes I was symptom free again. It says on the box "can start to work in 20 minutes and lasts 24 hours" - and that is certainly my experience. YMMV
Reactine is 10mg Cetirizine Hydrochloride. The store brand allergy remedy I bought was 10mg Loratidine - and that is what I have been buying in the past. I bought it simply because generic medication is often the same as brand name and usually cheaper. For instance Aspirin is Bayer's brand name but their product is always more expensive than the identical generic acetylsalicylic acid (ASA) . I do not know if any store sells generic cetirizine.
In the past I have out up with the less than satisfactory performance of loratidine. After all it was - it seemed - better than nothing and I thought was probably as good as it gets. Not so.
