Does Sancuso cause side effects?
Sancuso (granisetron transdermal patch system) is an anti-nauseant and antiemetic used to prevent nausea and vomiting resulting from chemotherapy for cancer. Other formulations of granisetron (for example, Kytril) are administered by mouth or injection.
Certain chemotherapeutic agents used for treating cancer stimulate the release of a neurotransmitter called serotonin from nerves in the brain. Neurotransmitters are chemicals that nerves use to communicate with one another.
Released serotonin binds to other nerves in an area of the brain called the chemoreceptor trigger zone, causing nausea and vomiting. Granisetron, the active ingredient in Sancuso, prevents serotonin from binding to nerves in the chemoreceptor trigger zone thereby preventing nausea and vomiting.
Common side effects of Sancuso include
- abdominal pain,
- chest pain, and
- application site reactions (redness, bumps, rashes, blisters).
Allergic reactions may occur rarely.
Serious side effects of Sancuso include severe
- redness, itching, swelling, or other irritation where the patch is worn; and
- high levels of serotonin in the body (symptoms include agitation, hallucinations, fever, fast heart rate, overactive reflexes, nausea, vomiting, diarrhea, loss of coordination, fainting).
Drug interaction studies have not been conducted with Sancuso. Sancuso is broken down in the body by cytochrome P-450 liver enzymes.
What are the important side effects of Sancuso?
The most common adverse effects of granisetron are
Other adverse effects include
Allergic reactions may occur rarely.
Application site reactions (redness, bumps, rashes, blisters) may occur. The patch must be removed if serious skin reactions or generalized skin reactions occur. Light exposure (sunlight, sun lamps, tanning beds) may reduce the effect of granisetron, and granisetron may cause light sensitivity.
To avoid light exposure, the application site should be covered with clothing during therapy and for 10 days after the patch is removed. Granisetron may mask the symptoms of certain gastrointestinal conditions, for example, gastroparesis or ileus (paralysis of the muscles of the stomach and small intestine, respectively) by reducing the nausea and vomiting that are their primary symptoms.

Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of Sancuso was evaluated in a total of 404 patients undergoing chemotherapy who participated in two double-blind, comparator studies with patch treatment durations of up to 7 days. The control groups included a total of 406 patients who received a daily dose of 2 mg oral granisetron, for 1 to 5 days.
Adverse reactions occurred in 8.7% (35/404) of patients receiving Sancuso and 7.1% (29/406) of patients receiving oral granisetron. The most common adverse reaction was constipation that occurred in 5.4% of patients in the Sancuso group and 3.0% of patients in the oral granisetron group.
Table 1 lists the adverse reactions that occurred in at least 3% of patients treated with Sancuso or oral granisetron.
Table 1: Incidence of Adverse Reactions in
Double-Blind, Active Comparator Controlled Studies in Cancer Patients Receiving
Chemotherapy (Events ≥ 3% in either group)
|Body System Preferred Term||Sancuso TDS N=404 (%)||Oral granisetron N=406 (%)|
|Nervous system disorders|
5-HT3 receptor antagonists, such as granisetron, may be associated with arrhythmias or ECG abnormalities. Three ECGs were performed on 588 patients in a randomized, parallel group, double-blind, double-dummy study: at baseline before treatment, the first day of chemotherapy, and 5 to 7 days after starting chemotherapy.
QTcF prolongation greater than 450 milliseconds was seen in a total of 11 (1.9%) patients after receiving granisetron, 8 (2.7%) on oral granisetron, and 3 (1.1%) on the patch. No new QTcF prolongation greater than 480 milliseconds was observed in any patient in this study. No arrhythmias were detected in this study.
Adverse reactions reported in clinical trials with other formulations of granisetron include the following:
- Gastrointestinal: abdominal pain, diarrhea, constipation, elevation of ALT and AST levels, nausea and vomiting
- Cardiovascular: Hypertension, hypotension, angina pectoris, atrial fibrillation and syncope have been observed rarely
- Central Nervous System: dizziness, insomnia, headache, anxiety, somnolence and asthenia
- Hypersensitivity: rare cases of hypersensitivity reactions, sometimes severe (e.g. anaphylaxis, shortness of breath, hypotension, urticaria) have been reported
- Other: fever; events often associated with chemotherapy have also been reported: leucopenia, decreased appetite, anemia, alopecia, thrombocytopenia.
The following adverse reactions have been identified during post approval use of Sancuso. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
What drugs interact with Sancuso?
Sancuso (granisetron transdermal patch system) is an anti-nauseant and antiemetic used to prevent nausea and vomiting resulting from chemotherapy for cancer. Common side effects of Sancuso include constipation, headache, anxiety, dizziness, diarrhea, abdominal pain, chest pain, and application site reactions (redness, bumps, rashes, blisters). Allergic reactions may occur rarely. There are no adequate and well-controlled studies of Sancuso in pregnant women. It is unknown if Sancuso is excreted in breast milk.

Cancer Risk Factors
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Certain behavioral, lifestyle, and environmental factors contribute to cancer. Cancer prevention involves modifying these factors to decrease cancer risk. Tobacco use, alcohol consumption, physical inactivity, inadequate fruit and vegetable intake, and obesity increase the risk of certain cancers. Vaccines, genetic testing, and cancer screening also play a role in cancer prevention.
Cancer pain results from the tumor pressing on nerves or invading bones or organs. Cancer treatments like chemotherapy, radiation, or surgery can also cause pain. Over-the-counter pain relievers, prescription medications, radiation, biofeedback, and relaxation techniques are just some treatments for cancer pain.
Cancer fatigue is a lack of energy that is caused by cancer or cancer treatment, including chemotherapy, radiation, biological therapy, or bone marrow transplantation. Strategies to combat cancer fatigue include scheduling rest, pacing oneself, planning ahead and prioritizing work and activities, eating the right foods, exercising, and practicing proper body mechanics.
Is Cancer Contagious?
Cancer is an abnormal growth of cells. A variety of parasites and viruses have been linked to various cancers. Cancer may metastasize, spreading from its original location to other organs. If you have cancer, you should seek medical care immediately if you experience high fever, shortness of breath, intense headaches, vomiting blood or passing blood rectally, chest pain or moderate to severe weakness, passing out (fainting), mental status changes, or seizures.
What Is the BRCA Gene?
BRCA genes (BRCA 1 and 2, when normal, repair damaged DNA) are among the genetic mutations linked to breast cancer, ovarian cancer, and other cancers when mutated. Every woman with a BRCA mutation is at high risk for breast cancer, irrespective of whether she has a family history of breast cancer or not. By age 80, a woman with a BRCA mutation has about an 80% chance of developing breast cancer. BRCA1 and BRCA2 gene mutations also increase the risk of ovarian cancer, by 54% and 23%, respectively.
Prostate Cancer Treatment: Chemotherapy, Bone-Targeted and Immune Therapy
Doctors may introduce chemotherapy and immune therapy if other measures fail to cure a case of prostate cancer. However, unlike with other forms of cancer, chemotherapy isn’t the first choice for early prostate cancer. Immune therapy uses the body's own immune system to attack the prostate tumor, while bone-targeted therapy aims to preserve bone and prevent metastasis.
Where does bone cancer usually start?
Bone cancer occurs when there is an abnormal multiplication of the bone cells. It can arise from any bone in the body. The most commonly affected bones are the pelvis (hip bone) and long bones in the arms and legs such as the humerus and femur bone. Bone cancer is rare.
Which Is the Deadliest Cancer?
Lung cancer is considered to be the most deadly cancer. More people die from lung cancer each year than from breast, colorectal and prostate cancer combined.
What Are the Top Ten Cancers?
Lung cancer is the number one killer cancer in the world. It is the most common cause of cancer-related deaths in both men and women.
At What Stage of Cancer is Chemotherapy Used?
The decision to use chemotherapy may vary depending on the aggressiveness, stage and type of cancer. Usually, chemotherapy may be used for all stages in most cancer types. Chemotherapy is a type of medicine or combination of medications that is used to treat or kill cancer cells.
What Foods Increase the Risk of Cancer?
Cancer is one of the leading causes of death globally. Certain foods are deemed co-carcinogenic or have the potential to cause cancer. There is strong evidence linking diet with an increased incidence of specific cancers.
Which Cancer Is the Most Painful?
Cancer spreading to the bone is the most painful type of cancer. Pain can be caused by a tumor pressing on the nerves around the bone. As the tumor size increases, it can release chemicals that irritate the area around the tumor.
