I've got 2 packs of antihistamine tablets (Glapharm hayfever and allergy relief) - the packet Ive been using are called 'cetirizine hydrochloride'. I bought a new pack to use, thinking they were the same but these new ones are called ' cetirizine dihydrochloride' - what's the difference & will it be ok for me to take the new pack?

They are probably the same thing, one simply has more accurate labeling. The dihyrochloride simply means there are two Chloride anions to neutralize the cationic medicine. It dooesn;t affect its functionality or dosage.
Cationic salts are given as salts of HCl to yield a neutral chemical.

I'm no doctor, and I'm not entirely sure of the difference.. so, haha, allow me to answer your question. The thing I do know is that Dihydrochloride can/will make you sleepy. Hydrochloride, not so much.
