Candox is a centrally acting, strong painkiller from the
group of opioids.

• Some antiepileptic medicines and also the herbal
remedy ‘St John Wort’ can decrease the effect of
Candox is used to treat severe pain, which can be
adequately managed only with opioid analgesics.

Candox with food, drink and alcohol
Drinking alcohol whilst taking Candox may make you
feel more sleepy or increase the risk of serious side
effects such as shallow breathing with a risk of stopping
breathing, and loss of consciousness. It is
recommended not to drink alcohol while you’re taking
Grapefruit juice can inhibit the metabolism of
oxycodone which will increase its effect. Therefore you
should avoid drinking grapefruit juice while taking
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be
pregnant or are planning to have a baby, ask your
doctor or pharmacist for advice before taking this
You should not take Candox during pregnancy. There
are limited data from the use of oxycodone in pregnant
women. Oxycodone crosses the placenta into the blood
circulation of the baby.
Prolonged use of oxycodone during pregnancy can
cause withdrawal symptoms in newborns. Infants born
to mothers who have received opioids during the last 3
to 4 weeks before giving birth should be monitored for
You should not use Candox when you are
breast-feeding as oxycodone passes into breast milk
and may cause respiratory depression in the newborn.

Dependence and tolerance
Candox has primary dependence potential. When used
for a long time, tolerance to the effects may develop
and progressively higher doses may be required to
maintain pain control.
Chronic use of Candox may lead to physical
dependence and a withdrawal syndrome may occur
upon abrupt cessation. When a patient no longer
requires therapy with oxycodone hydrochloride, it may
be advisable to taper the dose gradually to prevent
symptoms of withdrawal.
When used as directed in patients suffering from
chronic pain the risk of developing physical or
psychological dependence is markedly reduced and
needs to be weighed against the potential benefit.
Please discuss this with your doctor.
