I recently have been experiencing symptoms of flu a after being in contact with someone who was diagnosed with it. is there any over the counter medications that are best recommend?

Depends on details: For Flu A or B, a doctor might prescribe Tamiflu if early in the illness. If it's a cold virus, there are no useful antivirals. Some people take extra vitamin C (may upset the stomach) and some take extra zinc (most lozenges have lots of sugar) but how much these things help is uncertain. Avoiding overexertion is wise. Anti-inflammatories like Tylenol or Motrin can help decrease aches and fevers.
