Doctors often prescribe Reliferon 3MIU Injection for chronic hepatitis B and C cases. It also treats multiple myeloma, follicular lymphoma, and hairy cell leukemia in patients. A healthcare professional always gives the injection to you. The treatment length really depends on how your condition is doing. You have to follow the prescription just as it says. Using it wrong can lead to some serious side effects down the line. Common ones include headache, dizziness, insomnia, nausea, and vomiting that might bother you. This drug can lower your blood cell counts quite a bit. That increases the risk of infections more than usual. So report any unusual symptoms to your doctor right away. Regular blood tests become necessary during the course. Always inform your doctor about liver or kidney problems, mental health issues, and every other medication you take. Avoid this injection completely during pregnancy or breastfeeding periods. Use effective contraception if you could become pregnant.
