If you don't have a provider who is savvy about hep C, get one. When you change providers, make sure you discuss HCV in your total care planning. If you are positive, take other precautions to protect your liver. Avoid alcohol entirely if you can, or keep your intake under one drink a day on average. Stop any other recreational drugs if you can.
Liver toxicities can pile up quickly and exacerbate each other.
If you are HCV positive, take precautions to avoid spreading it to others. Don't share apparatus or needles, especially. Sexual transmission risk appears to be much less, but a condom is safest. Advocate for more hepatitis research. Spread the word.
