Enjaymo can cause serious side effects, including:

Serious infections. Enjaymo is a prescription medicine that affects your immune system. Enjaymo can lower the ability of your immune system to fight infections. People who take Enjaymo may have an increased risk of getting infections caused by certain kinds of bacteria such as Neisseria meningitides, Streptococcus pneumoniae, and Haemophilus influenzae. These infections may be serious or life-threatening. Some infections may quickly become life-threatening or cause death if not recognized and treated early.

  • You need to receive vaccinations against infections caused by certain kinds of bacteria at least 2 weeks before your first dose of Enjaymo. You may need to have additional vaccinations during treatment with Enjaymo.
  • If your healthcare provider decides that urgent treatment with Enjaymo is needed, you should receive vaccinations as soon as possible.
  • Vaccinations may reduce the risk of these infections, but do not prevent all infections. Call your healthcare provider or get medical help right away if you get any new signs and symptoms of an infection, including:

    • severe headache with stiff neck or back
    • pain during urination or urinating more often than usual
