Effectiveness
How Lonsurf Affects PatientsTipiracil stops the body from changing trifluridine into a form that does not work. This lets trifluridine to be more effective in the body. Tipiracil also prevents the enzyme thymidine phosphorylase from working. This enzyme causes blood vessel growth, so blocking it can help treat some diseases.
How Lonsurf works in the bodyTipiracil keeps the active component of trifluridine in the body for longer, making it more effective. It also helps to reduce the presence of a protein linked to the growth of tumors, which can make them more aggressive. This means that tipiracil can help stop tumor growth or even shrink tumors.

Lonsurf Reviews: What are patients saying about Lonsurf?
3.7Patient Review
12/14/2016 I experienced hair loss after the first round of treatment, which was frustrating. However, the medication was easy to take with few other side effects.
1.7Patient Review
12/29/2017 The side effects of this treatment were really terrible. It completely ruined my sense of taste and made it hard to eat. I also felt incredibly flu-like, with a messed up digestive system and regular nausea and vomiting. Overall, I don't think the benefits are worth the cost.
1.3Patient Review
3/15/2016 Unfortunately, this medication has been very tough on my stomach. I've had a lot of pain and bloating as well as gas. After the first treatment, my CEA went from 298 to 990. However, I am starting my second round of treatment and am hopeful that it will start to lower my count again.
1.3Patient Review
6/15/2016 Lonsurf was totally ineffective and it decreased the quality of my life significantly.
1Patient Review
7/18/2021 My wife's health rapidly declined after she started taking this medication. We fought for a CT scan against our oncologist's advice and found that the cancer was growing everywhere. I expressed my dissatisfaction with her doctor.
1Patient Review
12/23/2021 I would not recommend this treatment to anyone. My husband died after taking it and he was only getting worse with each cycle.
1Patient Review
7/12/2022 Avoid this treatment at all cost! I started taking it and just a few days later ended up in the ER in severe pain. My quality of life decreased drastically; I was short of breath, depressed, and my thinking changed. All of this in such a short time after starting the treatment.
1Patient Review
2/23/2020 I metastatic colon and rectal cancer to my lungs, and this treatment unfortunately didn't work for me. My hair started falling out and the tumor grew. I'm now on intravenous chemotherapy.
1Patient Review
12/23/2021 I am so incredibly saddened by the death of my husband. He started taking Lonsurf and within weeks was sleeping all the time, to the point where it became dangerous. We had no warning signs that this medication would be deadly.
1Patient Review
12/23/2021 My husband was living with cancer for about 10 years. He was doing well, active and working a full time job until he started taking lonsurf. He only took it for 3 cycles before he went downhill fast and passed away. If we had only read these bad experiences, he might still be alive!
