Anti-Nausea DrugsĀ and Their Side Effects

How Anti-Nausea Side Effects Works

Cancer treatments can often cause nausea and vomiting, and to help manage this, doctors prescribe anti-nausea medicines. These drugs work in different ways and can be very effective, but like all medications, they can also come with side effects. Most side effects are mild and go away quickly, but knowing what to expect and when to speak up is important.

Common Side Effects of Serotonin Blockers

Some anti-nausea medicines, like serotonin blockers (e.g., ondansetron), can cause headaches or constipation. Steroids such as dexamethasone, often used alongside chemotherapy, might lead to trouble sleeping, mood changes, or mild discomfort during injection. These side effects usually improve when the medicine is stopped.

Antihistamines, Metoclopramide & Prochlorperazine

Other medications, like antihistamines (e.g., lorazepam or cyclizine), may make you feel sleepy, while drugs like metoclopramide or prochlorperazine can, in rare cases, cause muscle twitching, especially in younger people.

Domperidone, Aprepitant & Olanzapine

Domperidone might lead to a dry mouth or, rarely, uncontrolled movements. Newer options like aprepitant may cause fatigue, headaches, or constipation, and olanzapine can cause drowsiness or dizziness.

When to Talk to Your Doctor?

Always tell your doctor or nurse if you notice any side effects. They can usually help by adjusting your medication or offering something else for coping with side effects.
