Hello and welcome sir. Your doctor friend has prescribed a regimen to trest an infection, most probably an upper respiratory tract infection. The first thing I would like to say is that you need to always inform your wife s obstetrician about any medications you plan on giving your wife, as she is the one overlooking her pregnancy. I would personally not like to initiate any medications in a pregnant woman before consulting with her obstetrician. As for the medications, all of them carry a mild risk, but these seem to be averagely safe. Please only initiate them after her obstetrician has weighed the benefits versus risks. Hope this helps. Best wishes.
