Some common side effects from hepatitis C drug therapy treatment include headache, fever, fatigue, muscle aches and poor appetite, according to Healthline. Dry mouth, mouth ulcers and thick saliva are additional side effects that occur with treatment of hepatitis C. Diarrhea, nausea and vomiting are also common.
Hepatitis C treatment is also associated with some mental side effects, according to Healthline. Depression, low mood and anxiety are common side effects of drugs such Interferon, which is commonly used in treating the disease. Poor sleep and insomnia as well as irritability are often reported by those taking drugs to fight off hepatitis C.
Drugs used to treat hepatitis C can cause a flu-like reaction among users, notes Healthline. This reaction usually dissipates after a few weeks. While the side effects of treatment are generally not life-threatening, they can cause discomfort over the full course of hepatitis C treatment, which normally lasts anywhere from six months to an entire year.
Because hepatitis C treatment can be hard on the body, it is important for those undertaking treatment for the condition to be in as good health as possible before treatment commences, advises Healthline. Drinking plenty of water to avoid dehydration and eating a balanced diet that consists of nutritious foods can help to lessen the effects of the drugs used to fight hepatitis C.
