Chances are, acetaminophen is a mainstay in your medicine cabinet. You use it to ease aches and pains or bring down a fever.
When you follow the instructions on those pill-bottle labels, it's helpful and safe, and it generally doesn't upset the stomach like other pain relievers.
But if you take too much, it can hurt your liver. In extreme cases, it can even cause liver failure.
It’s still fine to use acetaminophen. You just need to know how to do that safely.
The good news is that most cases of the disease don’t last a long time. Your body fights it off within a few months, and you’re immune for the rest of your life. That means you can't get it again.
What Happens to People Who Have It?
Your doctor will know you’ve recovered when your blood tests show no signs of active infection.
But some people don't get rid of the infection. If you have it for more than 6 months, you’re what’s called a carrier, even if you don’t have symptoms. This means you can give the disease to someone else through:
Contact with your blood or an open sore
Sharing needles or syringes
Doctors don’t know why, but the disease does goes away in a small number of carriers. For others, it becomes what’s known as chronic. That means you have an ongoing liver infection. It can lead to cirrhosis or hardening of the organ. It scars over and stops working. Some people also get liver cancer.
If you’re a carrier, don’t donate blood, plasma, body organs, tissue, or sperm. Tell anyone you could infect, whether it’s a sex partner, or your doctor or dentist, that you have it.
How Common Is Hepatitis B?
The number of people who get this disease is down, the CDC says. Rates have dropped from an average of 200,000 per year in the 1980s to around 18,000 in 2012. People between the ages of 20 and 49 are most likely to get it.
Only 5% to 10% of adults and children older than 5 who have hepatitis B end up with a chronic infection. The numbers aren’t so good for those younger than 5 (25% to 50%) and even higher for infants infected at birth (90%).
As many as 1.4 million people in the U.S. are carriers of the virus.
