Buying Zyprexa online
While the original brand is widely recognised, generic olanzapine, often produced in India, offers a more affordable pathway for long-term health management. For expats and people living far from a well-stocked pharmacy, reliable sourcing ensures consistent access to therapy. This medication is best used under the guidance of a doctor.
Will I receive the original Zyprexa?
No. Zyprexa is the originator brand name, made by Eli Lilly, and Yasabai uses it to identify the medicine: you receive a generic with the same active ingredient (olanzapine) at the same dose, mostly a recognised Indian branded generic. The exact brand depends on stock.

It depends on the strength and pack. Zyprexa comes in 2.5, 5, 7.5, 10, 15 and 20mg strengths, in packs of 10 to 360 tablets, and the price per tablet for every option is shown above, in US dollars or the currency you choose. Larger packs cost less per tablet. Paying with Bitcoin or Ethereum gives you an extra 10% off.
