How Tecvayli Injection works
Tecvayli 30mg Injection looks for specific markers on the surface of the cancer cells. Once it finds the cancer cells, Tecvayli 30mg Injection also connects to your immune cells, which are the body's natural defense against illness. By linking the cancer cells to your immune cells, it helps the immune system recognize and attack the cancer cells, making it easier for your body to fight the disease.
Quick tips
- Be vigilant about monitoring for side effects, especially during the initial "step-up" doses. If you notice any unusual symptoms like fever, shortness of breath, or low blood pressure, contact your doctor immediately.
- Drinking plenty of fluids can help manage some side effects, such as fatigue and nausea. Hydration also supports overall health during treatment.
- Since Tecvayli 30mg Injection can weaken your immune system, take precautions to avoid infections. Wash your hands regularly, avoid close contact with sick individuals, and steer clear of large crowds when possible.
- Regularly update your doctor on how you are feeling during the treatment. This allows them to adjust your treatment plan as needed and provide additional support for managing side effects.
- Fatigue is a common side effect of Tecvayli 30mg Injection. Make sure to plan for rest periods in your daily routine to help your body recover and maintain your energy levels.
- Do not receive live vaccines during treatment with Tecvayli 30mg Injection, as they may pose a risk to your health. Check with your doctor before getting any vaccinations.
- If you are of childbearing age, use effective contraception during treatment and for a period afterward to prevent potential harm to an unborn baby.
