I loved ricola cough drops, ayr nasal spray, and the best was vicks breathe rite strips. They look dorky, but really do help!
You can take robitussin DM as well.
Tylenol cold, actifed, benadryl, chlortrimenton, chloraseptic spray, cough drops and Ayr nasal solution are all on the list of safe meds for colds from my doctor O and sudafed
There is stuff you can take. Call your doctor to find out what they say is safe.
