I take Certirizine daily, all year, as I have a sinus problem which results in eye pain if I don't. I have also tried many antihistamines for annual hayfever but this one suits me best. It is trial and error as to which one will be best for any individual.
This was originally prescribed by my GP but is now OTC (over the counter, i.e. available to the public without prescription) so I buy my own.
Certirizine is one of the non-drowsy antihistamines but to be sure, I take it at night.
Certirizine is cheapest when bought by mail order. It is sold under many branded names but it is completely unnecessary to buy any of these, which could easily be many times the price of the generic product, (sometimes five times as much!).
For the first time I recently ordered Certirizine from an online pharmacy (Pharmacy First, if I can give the name) and whilst the order took some time to arrive (but this was in the first few days of the recent pandemonium), I was kept updated and my order did come. I will use them again as their price for Certirizine was amazing. I have seen this drug branded elsewhere at £6 for a month, whereas I paid £2.75 for a four-month supply.
