Will the pills or packaging be different when I order from YouDrugstore?
If you usually take a brand name pill and have instead ordered a generic drug, your pills may look different. Although they may look different, generic versions of a drug have the same active ingredients and work in exactly the same way as the brand-name medication. The appearance of medication or packaging may also differ from country to country, even though the strength is the same. For example, Celexa 20MG is usually a peach-colored pill, but in Canada it is white and slightly smaller, even though the same company manufactures both pills. Two different brands of generic medication may also look different because they are made by different manufacturers, although they are equivalent in every other way.
How does medication from Canada differ from medication in other regions of the world?
Canada has high standards and regulations governing the manufacturing of medication and health products and the licensing of doctors and pharmacists. Despite some possible cosmetic differences, medication from Canada is the same quality and strength as medication from other areas like the United States.
Why are prices on YouDrugstore different from prices at other pharmacies?
Unlike some regions of the world, Canadian medication prices are regulated with limits on how much patients have to pay for their prescriptions. This means that Canadian drug costs are often lower than other regions.
