Typical dosage for MS

The following information describes the dosage of Mavenclad that’s commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosing regimen to fit your needs.

Mavenclad is not a medication that’s taken every single day for multiple sclerosis (MS). Instead, it’s taken as two treatment courses over a total of 2 years. Each treatment course includes two cycles per year, about a month apart. Each cycle is 4 or 5 days long.

You’ll take either one or two tablets of Mavenclad per day during treatment cycles.

Your doctor will determine your dose of Mavenclad based on your body weight in kilograms (kg).* Mavenclad’s usual dosing by weight is 3.5 mg of the drug per kg of body weight (mg/kg). This calculation is used to determine your total dose of Mavenclad that’s taken over 2 years.

Here’s an example of a Mavenclad dosing chart:

Body weightUsual doseCumulative dose of Mavenclad, taken over a total of 2 years
80 kg (about 175 lbs)3.5 mg/kg280 mg

*One kg is about 2.2 pounds (lb).

Below is an example of a Mavenclad treatment schedule:

First yearone treatment cycle of 4 or 5 daysno treatment cycleone treatment cycle of 4 or 5 daysno treatment cycle
Second yearone treatment cycle of 4 or 5 daysno treatment cycleone treatment cycle of 4 or 5 daysno treatment cycle

The chart above is just an example. Your doctor will give you specific instructions for how often to take Mavenclad. They’ll also instruct you about how many tablets to take per day during treatment cycles. You likely will not take more than the maximum of two tablets per day.

Note: After two treatment courses of Mavenclad, you should not take the drug again for at least 2 years. This is due to an increased risk of cancer. Mavenclad has a boxed warning about this risk, which is the most serious type of warning from the Food and Drug Administration (FDA). To learn more, see the Boxed Warning section at the beginning of this article or talk with your doctor.

Children’s dosage

Mavenclad is not approved for use in children.

Long-term use

Mavenclad is meant to be used as a long-term treatment. If you and your doctor determine that Mavenclad is safe and effective for you, you’ll likely take it long term.

Mavenclad comes as an oral tablet that you’ll take by mouth with water. You should not chew the tablets before swallowing. You can take Mavenclad tablets with or without food.

You’ll take either one or two tablets of Mavenclad per day during treatment cycles.

You should take your dose of Mavenclad 3 hours before or after any other medications that you take by mouth.

It’s important to keep Mavenclad tablets in their original package until you’re ready to take your dose. Be sure that your hands are dry before handling the tablets. Avoiding touching or holding Mavenclad tablets any longer than necessary. After taking your dose, wash your hands right away, along any other skin that came in contact with the tablets.

If you miss a dose of Mavenclad, you should skip the missed dose for now. Continue taking your prescribed dose each day of your treatment cycle. Then, you’ll extend your treatment cycle by 1 day to take the dose you missed.

Likewise, if you miss taking Mavenclad for 2 days in a row, you should extend your treatment cycle by 2 days. This way, you’ll take the doses you missed.

You should not take a double dose of Mavenclad to make up for a missed dose. You also should not take more than your prescribed dose of Mavenclad per day of your treatment cycle.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.

It’s important that you don’t use more Mavenclad than your doctor prescribes. For some medications, taking more than the recommended amount may lead to side effects or overdose.
