These side effects are often temporary, resolving within a few days to weeks. However, contacting your doctor if they persist, worsen, or become bothersome is essential.

What might help:

Ponvory vs. Tecfidera and Ocrevus: A Quick Comparison

Ponvory isn't the only treatment available for MS. Tecfidera and Ocrevus are alternative options. These medications belong to different drug classes, meaning they work differently and have varying side effects. For example:

• Ponvory and Tecfidera: Both can cause elevated liver enzyme levels and serious infections.
• Ponvory and Ocrevus: Both can lead to upper respiratory tract infections, cough, and arm/leg pain. They may also increase cancer risk.

A detailed discussion with your doctor or pharmacist can help you understand the differences and choose the most suitable option alongside their respective risk profiles.
