What Kind of Medicine Is Ceritinib?
Simply put, ceritinib is a type of targeted therapy. Traditional chemotherapy affects many healthy cells all over your body, but targeted therapies focus directly on specific targets inside cancer cells.
This medicine works by blocking certain proteins that tell cancer cells to multiply and grow. When those protein signals stop, the cancer cells lose their ability to spread and grow further.
Doctors primarily prescribe ceritinib to treat a specific type of lung cancer known as non-small cell lung cancer. Because it focuses directly on cancer cells rather than normal cells, some side effects may be different from standard chemotherapy. Zykadia is a well-known brand name for this medicine.
Things to Tell Your Doctor Before Starting Treatment
Before your doctor prescribes ceritinib, they need a complete picture of your overall health. Sharing your medical history keeps you safe and helps your medical team prevent potential complications.
Be sure to talk with your doctor if you have any of the following health conditions:
- You have diabetes or high blood sugar levels.
- You have heart disease or a history of irregular heartbeats.
- You have experienced inflammation of the pancreas, known as pancreatitis.
- You have liver disease or liver problems.
- Your blood test results show low levels of magnesium or potassium.
- You suffer from asthma or other lung and breathing problems.
- You are pregnant, planning to become pregnant, or currently breastfeeding.
- You have known allergies to ceritinib, lactose, gelatin, or any other foods, medicines, or preservatives.
How to Take Ceritinib Properly
Following the correct instructions when taking your medicine is essential for your treatment success and personal safety.
- Take it with food: You must always take this medicine with a meal and a full glass of water. Never take it on an empty stomach.
- Avoid grapefruit: Do not eat grapefruit or drink grapefruit juice while taking this medicine. It can change how your body absorbs the drug.
- Swallow whole: Swallow each pill whole. Do not crush, chew, break, or split the tablets.
- Stick to your schedule: Take your dose at the exact time and amount your doctor prescribes. Never change your dose or stop taking the medicine without medical advice.
Emergency Red Flags
If you suspect you or someone else took too much ceritinib, stay calm and call emergency services right away. In the US or Canada, call 911. In the UK, call 999, or go straight to the nearest Emergency Department (ER or A&E).
What to Do If You Miss a Dose
If you forget to take your medicine on time, do not panic. Check how much time remains until your next scheduled dose.
If your next dose is more than 12 hours away, take the missed pill right away. However, if your next dose is less than 12 hours away, skip the missed pill entirely and take your next dose at the normal time.
Never take two doses at the same time to make up for a missed pill. Taking extra medicine can cause dangerous complications.
