Side Effects of Pemetrexed
Preventing and Reducing Side Effects of PemetrexedDuring clinical trials, researchers realized that some pemetrexed side effects could be prevented at least somewhat by taking folic acid, vitamin B12, and a corticosteroid. As a result, the following measures are usually taken to help prevent side effects:
- You must take folic acid (as recommended by your healthcare provider) for at least 5 out of the 7 days before your pemetrexed infusion and continue until at least 21 days after your last dose.
- You must also receive vitamin B12 injections while taking this medication. You should get your first B12 injection during the week before your first pemetrexed infusion and then once after every three doses of pemetrexed (usually about once every nine weeks for most people).
- Your healthcare provider may choose to give you a corticosteroid medication, such as dexamethasone, to help prevent skin rashes due to pemetrexed. In most cases, the steroid is taken the day before, the day of, and the day after the infusion.
