Product Overview
Details
A once-daily antihistamine for seasonal allergies: pollen, dust, pet dander, the sneezing that starts in April and does not stop.
It is non-drowsy for most people. Most is not all — worth testing on a day where being drowsy would not matter.
How to take it
- One tablet daily, at the same time each day
- Start before the season rather than after it
- Requires a prescription at this strength
Always read the label, and speak to a pharmacist before starting anything new alongside a medicine you already take.
