Smiley face Smiley face

Avoid/Use Alternative

Smiley face Smiley face Mavyret (glecaprevir/ pibrentasvir) + OxyFast (oxycodone)

Avoid/Use Alternative


glecaprevir + oxycodone

use alternative or monitor respiratory rate; consider decr. oxycodone dose: combo may incr. oxycodone levels, risk of CNS and respiratory depression, psychomotor impairment, other adverse effects (hepatic metabolism inhibited)

pibrentasvir + oxycodone

use alternative or monitor respiratory rate; consider decr. oxycodone dose: combo may incr. oxycodone levels, risk of CNS and respiratory depression, psychomotor impairment, other adverse effects (hepatic metabolism inhibited)

Monitor/Modify Tx

Smiley face Smiley face cetirizine (generic) + OxyFast (oxycodone)

Monitor/Modify Tx


cetirizine + oxycodone

monitor respiratory rate; decr. oxycodone start dose by at least 50%, consider decr. cetirizine dose, use lowest effective doses and shortest duration of concomitant tx: combo may incr. risk of profound CNS and respiratory depression, psychomotor impairment (additive effects)

Smiley face Smiley face OxyFast (oxycodone) + Prinivil (lisinopril)

Monitor/Modify Tx


oxycodone + lisinopril

monitor BP: combo may incr. risk of severe hypotension, including orthostasis, syncope (additive effects)

Additional Considerations

Smiley face Smiley face oxycodone in OxyFast

consider prescribing an opioid overdose reversal agent, especially with concomitant CNS depressant use

add MAO inhibitor to Interaction Check if recent (14 days) use

Smiley face Smiley face pibrentasvir in Mavyret

caution advised with narrow therapeutic index drugs extensively metabolized in the liver; viral eradication may improve hepatic metabolic function, decr. levels, efficacy of concomitant drugs

monitor glucose with drugs used for diabetes tx; viral eradication may change hepatic function, alter blood glucose control resulting in serious symptomatic hypoglycemia

Smiley face Smiley face glecaprevir in Mavyret

caution advised w/ narrow therapeutic index drugs extensively metabolized in the liver; viral eradication may improve hepatic metabolic function, decr. levels, efficacy of concomitant drugs

monitor glucose w/ drugs used for diabetes tx; viral eradication may change hepatic function, alter blood glucose control resulting in serious symptomatic hypoglycemia
