Mouth sores or bleeding gums can lead to an infection. Stop taking methothrexate and call your cancer doctor for advice. Brush your teeth gently after eating and at bedtime with a very soft toothbrush. If your gums bleed, use gauze or your finger instead of a brush. Make a mouthwash with teaspoon baking soda or salt in 1 cup warm water and rinse several times a day.
Hair loss is rare with methotrexate.
Your hair will grow back once you stop treatment with methotrexate. Colour and texture may change. Use a gentle baby shampoo and soft brush. Avoid hair spray, bleaches, dyes and perms. Your skin may sunburn easily.
