How to reduce sides effects

Learn more about how methotrexate affects folic acid, as well as about the other possible side effects.

How does methotrexate affect folic acid?

Folic acid is a B vitamin.

An enzyme in the liver converts folic acid into folate, which plays many essential roles in the body, including helping with cell division and DNA replication.

Methotrexate works by reducing the amount of folic acid in the body, which means that harmful cells cannot replicate.

Taking folic acid

You may be prescribed folic acid tablets while taking methotrexate, a manufactured version of vitamin B9 (also called folate). Folic acid helps protect the healthy cells in your body and reduces some of the side effects of methotrexate.

You may be wary of the side effects of methotrexate.

A drop in white blood cells could cause infections—a dip in the production of blood platelets, which could cause abnormal bleeding. Still, most people tolerate the drug quite well, especially if they take folic acid, follow doctor’s instructions and practice other good health habits.

The only way to reduce the side-effect is to reduce the dose of the drug. However, taking folic acid on non-methotrexate days usually helps with the other side effects. If you’re currently on folic acid just once a week, it might be worth taking it on the six non-methotrexate days.

In addition to taking folic acid supplements, a person can also reduce the side effects of methotrexate by talking to a doctor about dosage.

Because methotrexate also depletes folic acid levels, it can cause various side effects, including mouth ulcers, headaches, and fatigue. Taking a folic acid supplement can reduce the risk of these side effects.

Dosage

According to the Arthritis Foundation, some doctors suggest taking 1 milligram (mg) of folic acid daily.

Other doctors may recommend taking a single 5-mg dose weekly.

Some people will take the folic acid supplement 24 hours after a methotrexate dose.

In a multi-study review of placebo-controlled clinical trials on the effects of folic acid supplementation, the authors made several conclusions: Folic acid reduced the risk of methotrexate side effects, such as nausea, vomiting, and stomach pain by 26 percent.

Your doctor may increase or decrease your methotrexate dose, depending on the results of your tests.

It’s important to record how much methotrexate you take and the consequences of your blood tests.

You must be aware of any symptoms or possible side effects to report them to your doctor promptly − and appropriate action can be taken if necessary.

Some serious side effects can occur without causing any symptoms you would immediately notice.

When a drug is used, it must balance its potential danger with its benefits.
