Effective antihistamine

This medication works like a dream for me, eliminating all allergic symptoms. I like the small dose in each pill as it allows me to vary the dose without trying to cut small tablets into fractions. I can take just one tablet for a small reaction ... or four tablets for a severe reaction. Many thanks for your excellent (and reliable service too

Dependable

The Chlorpheniramine is a 1st generation antihistamine that is very effective. Works to reduce nausea from migraine: eases Spring allergies; and even minimises the itches from mozzie bites. Oh, and it's great for inducing sleep on the odd insomniac night and to cap it all it's sooo inexpensive. What's not to love !
