Absolutely! Matter of fact I take the weekly .5 dose and the pen has enough left that I take two clicks extra using the same needle. I realized that when I finished the last .5 dose with a pen and there was still some left but not enough to equal another .5 or even another .25 dose. The first couple of months I simply added that extra to the last dose before refill. That was too much and I couldn’t even force myself to eat because I would get nauseated. I lost quite a bit of weight but that is not healthy.
