Prevymis is a prescription medication that is used to prevent cytomegalovirus (CMV) infection in adult patients who have received a hematopoietic stem cell transplant. CMV is a common virus that can cause serious complications in patients with weakened immune systems, such as those who have undergone a stem cell transplant.

Prevymis works by inhibiting the replication of CMV, helping to prevent the virus from causing infection in the body. It is typically taken orally once daily, and the dosage may vary depending on the patient’s individual circumstances.

It is important to follow your healthcare provider’s instructions carefully when taking Prevymis, and to report any side effects or concerns to them promptly. Common side effects of Prevymis may include diarrhea, headache, nausea, and vomiting.

Before starting Prevymis, it is important to inform your healthcare provider about any other medications or supplements you are taking, as they may interact with Prevymis and affect its effectiveness. It is also important to inform your healthcare provider if you have any allergies or medical conditions that may affect your ability to take Prevymis safely.

Overall, Prevymis is an important medication for patients who have undergone a stem cell transplant and are at risk for CMV infection. By taking Prevymis as prescribed and following your healthcare provider’s instructions, you can help protect yourself from the potentially serious complications of CMV infection.
