Should You Buy Quetiapine (Seroquel) Online?
Particularly in the United States, many individuals choose to purchase medications online, either for reasons of cost savings, privacy, or both. Both brand-name Seroquel and so-called ‘generic Seroquel’ (i.e., Quetiapine without the Seroquel brand name) can sometimes be purchased at deep discounts (and sometimes without a prescription) in this way. Before undertaking any purchase of medications online, however — and certainly if you are contemplating doing so without a prior prescription — please consider the integrity of the supplier and the national and/or local laws which may apply where you live.
