You can also dispense 2.5 mg doses from the 15 mg pen, then raise to 5mg after four weeks with the same pen. Each click on a 15 mg pen is 0.25mg, so 10 clicks give 2.5mg, 20 give 5mg, 30 give 7.5mg, 40 give 10mg, 50 give 12mg, and 60 clicks, a full pen dose, is 15mg. Counting clicks gets you any strength and works out cheaper. The savings card price is standard wherever you use it, so the same card at a regular pharmacy gives the same discount. But the medicine cost plus dispensing fees is lowest at the big-box pharmacies, in my experience about $60 less, which is significant.
