My husband is taking Z-pac, 2 capsules the first day, then one a day for five more days. This is day 3 and he is no better. He has no temperature, but has a headache and sore throat and just a bad cold ....blows his nose a lot and some coughing. He has Parkinson s Disease and is on several other medications. This is what his PCP told him to take in case he got a cold. We started it on Monday of this week. Could he take something else along with it for his headache, like Ibuprofen?
