For a cold, just don't take any medicine. If there's pain or a fever, take only Tylenol. BUT if she's got a fever, like you say, she should be calling an advice nurse and not waiting for the doctor to call back in a few days. I'm preg right now and have instructions to call if I get a fever of 100 degrees or higher.
As for the cold- I'm not a home remedy expert but chicken soup, hot drinks, lots of water to sip on (it washes the nose drainage down her throat so it doesn't irritate it). I know there's a Ricola she can suck on but I forgot... I had a terrible sore throat around 6 weeks myself and drank water, water, water.
Hope somebody hops on here with specific home remedies and certain non-medicinal things to avoid consuming.
