Notes
Used for OUD and chronic pain.
Buprenorphine is a partial opioid agonist given by the sublingual route. It's typically used in the pain relief category.
After one sublingual dose you'd typically start noticing the effect in 30 min – 1 hr. The drug reaches its highest blood level in about 1 hr – 4 hr, and a single dose usually keeps working for around 1 day – 3 days.
Let it dissolve fully under the tongue — don't chew or swallow it whole. Long-acting — take at roughly the same time each day for steady levels.
Don't combine with other products in the same drug class without checking with a pharmacist. Stop and seek medical advice if you have an unexpected reaction, severe side effect, or symptoms that don't improve.
All timings are approximate population ranges for a typical adult dose. Individual response varies with age, genetics, formulation, food, and other medications.
