I had a cold earlier in my PG and was told to take panadol for any fever. I was also told i could gargle the soluble panadol that dissolves for my throat, obviously don't take both, just one of the two panadol options. Otherwise most other products aren't 100% safe. I went and saw my chemist and that was all they could recommend. I believe it's the pseudoephedrine you need to avoid. I took the butter menthol soothers as they had honey and soothed but nothing medicate to cause a problem. Seemed to help at the time. The lemon/honey tea also works great.
