It is given as an infusion into the vein by a qualified medical professional, following the dosage and frequency determined by your doctor. It is important to take Keytruda exactly as prescribed to avoid serious side effects, such as rash, fatigue, fever, nausea, and muscle pain. It may take some time for you to notice the benefits of the treatment, so do not stop taking it unless your doctor advises you to.
During the infusion of Keytruda, serious side effects like chills or shaking, itching, rash, difficulty breathing, and dizziness may occur. Therefore, your doctor will monitor you closely for any allergic reactions. Before starting Keytruda treatment, inform your doctor about any lung disease, liver or kidney issues, or current medications you are taking to prevent potential interactions. Keytruda should not be used during pregnancy or while breastfeeding, and effective contraception is necessary for both males and females during treatment to avoid pregnancy complications.

Common side effects of Keytruda 100 mg Injection include diarrhoea, nausea, tiredness, rash, headache, and joint pain.

Benefits

In melanoma, which is a dangerous form of skin cancer, Keytruda works by targeting the genetic code of cancer cells, effectively killing them and halting their growth and spread within the body. With its mechanism of action, Keytruda offers a promising treatment option for those battling melanoma.
For patients with non-small cell lung cancer, Keytruda Injection proves to be a valuable treatment choice. It can be used either alone or alongside other medications to combat this type of lung cancer, which is prevalent among both smokers and non-smokers. However, it is important to note that Keytruda is a potent medication with potential toxicity, so discussing the risks and benefits with a healthcare provider is crucial. Patients undergoing Keytruda treatment should avoid alcohol consumption and prioritize hydration to manage potential side effects.
In cases of head and neck cancer, Keytruda Injection demonstrates its effectiveness by killing cancer cells and inhibiting their growth. By interfering with the multiplication of cancer cells, Keytruda helps control the progression of head and neck cancer. Similar to its usage in treating lung cancer, patients should be aware of the medication's potency and toxicity, and discussions with healthcare providers about risks and benefits are essential. Furthermore, avoiding alcohol and smoking while on Keytruda treatment and staying well-hydrated are recommended for optimal outcomes.
Keytruda Injection also plays a crucial role in combating cervical cancer, a type of cancer that affects the cervix in females. By targeting cancerous cells in cervical cancer, Keytruda serves as an anti-cancer medicine that aims to eliminate cancer cells. It is vital for individuals considering treatment with Keytruda to have a thorough discussion with their doctor regarding potential side effects and benefits. As with other indications, avoiding alcohol consumption and maintaining hydration levels are advised during treatment to manage any adverse effects effectively.
