Does suboxone thin your blood?

Not Medical Advice: Thrombocytopenia, also known as 'thin blood', is one of the uncommon (0.1% to 1%) side effects of Suboxone (buprenorphine / naloxone).

‘Thin blood’ is characterized by a drop in the amount of platelets in the blood. Whereas the normal levels of platelets are around 150,000 to 450,000 per microlitre, most definitions of it involve levels of 50,000 and below.

According to, you should get emergency medical help if you have any signs of an allergic reaction to Suboxone: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once or seek emergency medical attention if you have:

  • extreme weakness or drowsiness, weak or shallow breathing;
  • confusion, blurred vision, slurred speech;
  • nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
  • a light-headed feeling, like you might pass out; or
  • withdrawal symptoms - diarrhea, vomiting, shaking or shivering, runny nose, watery eyes, muscle pain, and feeling very hot or cold.

This medicine is more likely to cause breathing problems in older adults and people who are severely ill, malnourished, or otherwise debilitated.

Common Suboxone side effects may include:

  • tongue pain, redness or numbness inside your mouth;
  • constipation, mild nausea, vomiting;
  • headache or other pain;
  • sleep problems (insomnia);
  • increased sweating; or
  • swelling in your arms or legs.
