Headache
CV:
Hypertension
EENT:
Sinusitis
GI:
Abdominal pain, nausea, hepatic damage
HEMA:
Leukopenia pancytopenia, aplastic anemia, agranulocytopenia
INTEG:
Rash, inj site reaction
MISC:
Flulike symptoms, UTI, back pain, lupus-like syndrome,
increased cancer risk,
antibody development to this drug;
risk of infection (TB, invasive fungal infections, other opportunistic infections), may be fatal, Stevens-Johnson syndrome, anaphylaxis
RESP:
URI
,
pulmonary fibrosis, bronchitis
Absorption 65%, terminal half-life 2 wk, lower clearance with advancing age (40-75 yr), high RA factor
Increase:
serious infections—other TNF blockers, rilonacept
•
Do not use with anakinra, serious infections may occur
•
Do not give concurrently with vaccines; immunizations should be brought up to date before treatment
Increase:
ALT, cholesterol
•
RA:
pain, stiffness, ROM, swelling of joints before, during treatment
•
For inj site pain, swelling, redness; usually occur after 2 inj (4-5 days), use cold compress to relieve pain/swelling
Black Box Warning:
For infections (fever, flulike symptoms, dyspnea, change in urination, redness/swelling around any wounds), stop treatment if present; some serious infections including sepsis may occur, may be fatal; patients with active infections should not be started on this product
•
May reactivate hepatitis B in chronic carriers, may be fatal
Black Box Warning:
Latent TB before therapy, treat before starting this product
•
Anaphylaxis, latex allergy:
stop therapy if lupuslike syndrome develops
•
Blood dyscrasias:
CBC, differential periodically
Black Box Warning:
For neoplastic disease (lymphomas/leukemia) in children, adolescents, hepatosplenic T-cell lymphoma is more likely in adolescent males with Crohn’s disease or ulcerative colitis
•
Therapeutic response: decreased inflammation, pain in joints, decreased joint destruction
•
About self-administration if appropriate: inj should be made in thigh, abdomen, upper arm; rotate sites at least 1 inch from old site; do not inject in areas that are bruised, red, hard
•
That if medication is not taken when due, inject next dose as soon as remembered and inject next dose as scheduled
•
Not to take any live virus vaccines during treatment
•
To report signs of infection, allergic reaction, or lupuslike syndrome, immediately

Hepsera
Func. class.:
Antiviral
Chem. class.:
Adenosine monophosphate analog
Inhibits hepatitis B virus DNA polymerase by competing with natural substrates and by causing DNA termination after its incorporation into viral DNA; causes viral DNA death
Chronic hepatitis B
