Hi I have a prescription for Pseudoephedrin and loratadine 10 mg, I was taking the pseudoephedrin, one pill along with the loratadine, once a day. My question is, I ran out of the Pseudoephedrin, and my sinusus are really hurting. Can i take another sinus product, although I took the pills earlier about 8am. The sinus pills are careone sinus medicine from CVS drug stores.
