- Swallow each capsule whole with a full glass of water. Never chew, crush, open, or split the capsules open.
- You can take this medicine with or without food. However, the most important rule is to take it the exact same way every single time. If you take it on an empty stomach the first day, continue doing that consistently.
- Some people experience mild nausea after taking this medicine. Taking your dose when your stomach is empty or taking it right before bedtime can help reduce nausea.

Emergency Warning: If you suspect you or someone else has accidentally taken too much of this medicine, do not wait. Go right away to the nearest Emergency Department (ER) or call emergency services (911 in the US/Canada, 999 in the UK).
What to Do If You Miss a Dose
If you miss a scheduled dose of your medicine, do not panic. Ask your doctor how you should handle your next dose. Never take two doses at the exact same time to make up for a missed dose. If you vomit shortly after taking a pill, do not take another one right away. Simply wait for your next scheduled dose time.
Things to Watch Out For During Treatment
When you are receiving chemotherapy, you need to pay close attention to how your body feels and reacts.
General Discomfort and Infections
Chemo medicines target cancer cells, but they can also affect healthy cells in your body. Because of this, feeling tired, weak, or generally unwell is common during treatment. Always report any side effects to your doctor, but keep taking your prescribed course unless your doctor tells you to stop.
This medicine can lower your white blood cell count, which reduces your body's ability to fight off infections.
- Try to stay away from people who are sick with colds, flu, coughs, or sore throats.
- If you develop a fever, chills, severe fatigue, or diarrhea, do not try to treat it alone at home. Contact your doctor right away.
Skin Reactions
In rare cases, serious skin allergies can happen while taking this medicine. These reactions can sometimes appear weeks after starting treatment. If you notice a fever or cold-like symptoms accompanied by red or purple skin rashes, peeling skin, or swelling around your face, lips, neck, or underarms, seek medical help right away.
Bleeding Risks and Pregnancy Precautions
- This medicine can lower your blood platelets, which help your blood clot. Because of this, you may bruise more easily or bleed longer from minor cuts. Watch for unexplained bruising, tiny red spots on your skin, blood in your urine, or dark tarry stools, and report them to your doctor.
- Pregnancy warning: This is very important for family planning. Women must avoid getting pregnant while taking this medicine and for at least 6 months after stopping. Men must avoid fathering a child while taking this medicine and for at least 3 months after stopping. Do not donate sperm during this period.
- Because this treatment can affect your future fertility, talk openly with your doctor if you have any concerns about starting a family later in life.
