WE received several packets from our Dr., and we only have to use it whenever our child is sick. So, we use 1 or 2 respules and then store the rest. Thankfully, he isn't sick every 2 weeks, but then we have to throw away 2-3 respules when he does get sick for a few months because the foil bag was opening. I just see $ going down the drain and I cna't find an answer as to why. If it's kept out of sunlight, I don't understand why it can't be used more than 2 weeks later.
