What to do with 12 DOSES of DMSA LEFTOVER after son got sick?

[Guest guest]

I have 12 doses of TD DMSA leftover after my son got sick last

weekend. Could I give just those 12 doses this weekend? Is that not

enough to do a round? Just 2 days worth. I've been doing .5ml every

4 hours.

Will the DMSA go bad? I've noticed that when I get the two rounds of

cream in the mail, the first round seems stronger smelling and leaves

a red spot on his stomach when I first rub it in. Then the next round

doesn't smell as strong and doesn't leave a noticable red spot. I've

felt that the 2nd round is weaker.

I feel like I wasted $26 last weekend when he got sick.

Thanks.
