What Is This Medicine Exactly?
This medicine contains two active ingredients called Trifluridine and Tipiracil. It is most commonly known by its brand name, Lonsurf. Simply put, it is a type of chemotherapy pill that slows down the rapid growth of cancer cells in your body.
Cancer cells grow and divide much faster than normal, healthy cells. This medicine works by stopping that rapid division and helping control how the cancer spreads. Because it comes in oral pill form, you can take your treatment conveniently when instructed by your care team.

How Should You Use This Medicine?
Following the exact instructions for taking this medicine is crucial for your success and safety. Always adhere strictly to the schedule provided by your oncologist or nurse.
- Follow Doctor Orders: Take your prescribed dose exactly as directed by your doctor. Your prescription might include different pill strengths, so read your medicine label carefully every time.
- Swallow Whole: Swallow each pill completely with a full glass of water. Never crush, cut, chew, or break open the pills under any circumstances.
- Take with Food: Taking this medicine shortly after finishing a meal is generally the best approach.
- Stick to the Schedule: Take your doses at the exact times recommended by your doctor. Never take extra pills or double up on doses without direct medical guidance.

What If You Take Too Much? (Overdosage)
If you suspect you took more medicine than prescribed, act quickly. Call your local emergency services or poison control center right away. In the UK, call 999 or NHS 111. In the US and Canada, call 911. Alternatively, head directly to the nearest hospital emergency department for professional medical evaluation.
What If You Miss a Dose?
Never take an extra dose to make up for a missed pill. Taking extra medicine can be dangerous and cause severe side effects. Call your doctor right away to ask what steps you should take next.
Things to Watch Out For During Treatment
Your body needs extra care and gentle attention while you undergo this cancer treatment. Pay close attention to how you feel every single day.
Pregnancy and Breastfeeding
- For Women: You must use reliable birth control while taking this medicine and for at least six months after your final dose.
- For Men: If you take this medicine, use effective contraception during treatment and for at least three months after stopping. This prevents harm to an unborn baby.
- Breastfeeding Mothers: Avoid breastfeeding while taking this medicine and for at least one full day after your last dose.
Managing Infections
This medicine temporarily lowers your body's immune system, making it harder to fight off illnesses.
- If you develop fever, chills, cough, or a sore throat, contact your doctor right away without waiting.
- Never take over-the-counter pain relievers like aspirin, ibuprofen, or paracetamol without consulting your doctor first. These can mask fevers and hide signs of a developing infection.
- Stay away from crowded public places and people who are currently sick whenever possible.
Bleeding Risks
Your blood clotting ability can decrease during this treatment, raising your risk of bruising or bleeding.
- Be very gentle when brushing and flossing your teeth to avoid gum bleeding.
- Inform your dentist that you take this medicine before undergoing any dental procedures.
- Report unexplained bruises, nosebleeds, or unusual bleeding spots on your skin to your doctor right away.
