1. What BuTrans patches are
and what they are used for
BuTrans patches contain the
active ingredient buprenorphine
which belongs to a group of
medicines called strong analgesics
or ‘painkillers’. They have been
prescribed for you by your doctor
to relieve moderate, long-lasting
pain that requires the use of a strong
BuTrans patches should not be used
to relieve acute pain.
BuTrans patches act through
the skin. After application,
buprenorphine passes through the
skin into the blood. Each patch lasts
for seven days.

2. Before you use BuTrans
Do not use BuTrans patches:
• if you are allergic (hypersensitive)
to buprenorphine or any of the
other ingredients of BuTrans
• if you have breathing problems;
• if you are addicted to drugs;
• if you are taking a type of medicine
known as a monoamine oxidase
inhibitor (examples include
tranylcypromide, phenelzine,
isocarboxazid, moclobamide and
linezolid), or you have taken this
type of medicine in the last two
• if you suffer from myasthenia

Step 4: Press the patch against your
skin with the palm of your hand and
count slowly to 30. Make sure that
the whole patch is in contact with
your skin, especially at the edges.
Wearing the patch
You should wear the patch for seven
days. Provided that you have
applied the patch correctly, there is
little risk of it coming off. If the edges
of the patch begin to peel off, they
may be taped down with a suitable
skin tape. You may shower, bathe or
swim whilst wearing it.
Do not expose the patch to extreme
heat (e.g. heating pads, electric
blanket, heat lamps, sauna, hot tubs,
heated water beds, hot water bottle,
etc) as this may lead to larger
quantities of the active ingredient
being absorbed into the blood than
normal. External heat may also
prevent the patch from sticking
properly. If you have a high
temperature this may alter the
effects of BuTrans patches (see
“Take special care” section above).
In the unlikely event that your patch
falls off before it needs changing, do
not use the same patch again. Stick
a new one on straight away (see
“Changing the patch” below).

Changing the patch
• Take the old patch off.
• Fold it in half with the sticky side
• Open and take out a new patch.
Use the empty pouch to dispose of
the old patch. Now discard the
pouch safely.
• Even used patches contain some
active ingredient that may harm
children or animals, so make sure
your used patches are always kept
out of the reach and sight of them.
• Stick a new patch on a different
appropriate skin site (as described
above). You should not apply a new
patch to the same site for 3-4 weeks.
• Remember to change your patch at
the same time of day. It is important
that you make a note of the time of
