Pain or tenderness may occur where the needle was placed. Apply cool compresses or soak in cool water for 15-20 minutes several times a day. The arm should be moved or used as much as comfortable, to keep the vein from hardening. You may notice a metallic taste as mechlorethamine is being given. Nausea and vomiting may occur after your treatment and may last for 8-24 hours.
Some people have little or no nausea.
You may be given an antinausea drug with your treatment and a prescription to take at home. It is easier to prevent nausea than treat it once it has occurred. Follow antinausea drug directions closely. Drink plenty of liquids. Eat often in small amounts.
