Interferon Beta-1b Dosing
The recommended interferon beta-1b dosage is 0.25 mg injected every other day. Your healthcare provider will most likely start you at a low dose (0.0625 mg) and slowly work you up to the full dosage. For the medication to work properly, you must follow interferon beta-1b dosing guidelines carefully and administer the injection every other day.
The dose of interferon beta-1b (Betaseron®, Extavia®) that your healthcare provider recommends will vary depending on a number of factors, including:
- How you respond to interferon beta-1b
- Other medical conditions you may have
- Other medications you may currently be taking.
As always, do not adjust your interferon beta-1b dose unless your healthcare provider specifically instructs you to do so.
The recommended interferon beta-1b dose for treating multiple sclerosis (MS) is 0.25 mg injected every other day. This is the same as 1 mL of interferon beta-1b, if you have mixed it correctly. It is recommended that you start at a low dose and slowly work up to the full dose, as follows:
- Weeks one and two -- interferon beta-1b 0.0625 mg (0.25 mL once mixed)
- Weeks three and four -- interferon beta-1b 0.125 mg (0.5 mL once mixed)
- Weeks five and six -- interferon beta-1b 0.1875 mg (0.75 mL once mixed)
- Week seven and beyond -- interferon beta-1b 0.25 mg (1 mL once mixed).
Your healthcare provider may recommend taking a non-prescription pain reliever, such as Tylenol® (acetaminophen) before, at the same time, or after each interferon beta-1b injection. This can help prevent some of the flu-like symptoms (such as a fever, chills, and muscle aches) common with interferon beta-1b.
