My mother tested negative for covid19 after a family member tested positive. she initially had a sour throat and cough and is currently taking cold/flu medication. her issue at the moment is that she's feeling fatigued, can she take anything?

COVID 19 negative: Was she symptomatic when she tested? Has she worsened significantly? If answers are no & yes, have her talk with her PCM. Rest, hydrate, & eat healthfully. Consider use of acetaminophen, saline for nasal irrigation, decongestant or cough syrup. Get urgent care for difficulty breathing, blue lips, persistent chest pain/ pressure or new onset confusion.
