Buying Seroquel online
Providing consistent access to medication is often a challenge for expats and those living far from a well-stocked pharmacy.

Is the Seroquel on SGMeds a generic?
Yes. SGMeds ships a generic with the same active ingredient (quetiapine) at the strength you choose, not the original Seroquel made by AstraZeneca. We use the brand name so you can find the medicine, and the generic's manufacturer varies with stock.
