By Mistake, I May Have Taken 1 Caplet Of Calcium

By mistake, I may have taken 1 caplet of calcium citracal (315 mg. calcium, 250 IU vitamin D) - instead of 1000 mg of vitamin C - with 1 tablet of iron (as ferrous sulfate, 65 mg. 361% daily value). Is that a serious problem? I have a cold. Would it be ok to take vitamin C tablet or use Emergen C packet in an hour - hour and 1/2? Thank you.
