Usual tree pollen allergy, and it's bad this year!
I know the packet says one tablet per day, but the effects wear off after 12 hours. A friend (who is a medical person:) ) said a day may mean 12 hours, not 24, but she's not at work until Wed and can't access her website.
Anyone know, or have access to the National Formulary who can check?
Cheers. xxx
