Please note that psychological and physical addiction
can develop in patients on Aceon. During long-term
use, the effects of this medicine may weaken, so that it
becomes necessary to use a higher dose (development
of tolerance). For this reason, Aceon must be used for
short periods only and under strict medical supervision
in patients at risk of developing drug dependence.
Please also inform your doctor if any of these problems
develops while you are taking this medicine and if you
have experienced such problems in the past.

The usual doses are given below. Your doctor may gradually increase or decrease
your dose depending on how you respond to the treatment.

Do not take Aceon at the same time as medicines called
“monoamine oxidase inhibitors” (which are used to treat
depression), or if you have taken one in the past 2
weeks. The combination could result in a serious,
potentially life threatening interaction.
The pain-relieving effect of Aceon may be weakened
and/or shortened if you also take medicines containing:
! carbamazepine (used to treat epilepsy)
! pentazocine, nalbuphine or buprenorphine
! ondansetron (used to prevent nausea or vomiting)
The risk of side effects increases:
! if you are taking medicines which may cause
convulsions (fits), such as certain antidepressants
or antipsychotics. The risk of having a fit may
increase if you take Aceon at the same time. Your
doctor will tell you whether Aceon is suitable for you.
! if you are taking certain antidepressants. Aceon
may interact with these medicines and you may
experience symptoms such as involuntary, rhythmic
contractions of muscles, including the muscles that
control movement of the eye, agitation, excessive
sweating, tremor, exaggeration of reflexes,
increased muscle tension, body temperature above
38 °C.
! if you are taking sedative medicines such as
tranquillizers, sleeping pills, antidepressants and
other pain relievers (morphine, codeine). You may
feel excessively drowsy or feel that you might faint.
! if you are taking medicines that inhibit blood clotting,
such as warfarin. The dose of these medicines may
need to be reduced, otherwise there could be an
increased risk of potentially serious bleeding
! if you are taking ketoconazole (an antifungal
medicine), ritonavir (an anti-HIV drug) or
erythromycin (an antibiotic)
! if you are taking alcohol
Aceon with alcohol
Do not drink alcohol while taking Aceon; this could make
side effects more likely to occur.
Pregnancy and breast-feeding

any medicine.
Pregnancy: There is very little information regarding
the safety of tramadol in human pregnancy, therefore
this medicine should not be used in pregnant women.
Breast-feeding: This medicine should not be used
during breast-feeding, since small quantities of
tramadol are excreted into breast milk. However, it is
normally not necessary to interrupt breast-feeding for a
single dose of tramadol. Please consult your doctor.

drowsiness and blurred vision. If this happens, do not

150mg tablet or one 200mg tablet twice daily.

control your pain. You should not take a dose of more than 400 mg of the active
substance daily unless there are specific medical reasons for this.
Children under 12 years:
