What TARGIN tablets are taken for
TARGIN tablets contain two different medicines called oxycodone hydrochloride and
naloxone hydrochloride anhydrous. Oxycodone belongs to a group of medicines called
opioid analgesics. Naloxone is a medicine which, when taken orally, can block some
of the effects of opioids in the gut, such as constipation.
TARGIN tablets are used to relieve moderate to severe persistent pain when other forms
of treatment have not been effective. The naloxone in TARGIN tablets will help prevent
and treat opioid-induced constipation.
Restless legs syndrome:
TARGIN tablets are also used to relieve the symptoms of severe to very severe restless
legs syndrome in people who can't be treated with dopamine medicines. People with
restless legs syndrome have unpleasant sensations in their limbs. This can start as
soon as they sit or lie down and is only relieved by an irresistible urge to move
the legs, sometimes the arms and other parts of the body. It makes sitting still and
sleeping very difficult.
TARGIN tablets helps to relieve the unpleasant sensations and so reduces the urge
to move the limbs.
Your doctor, however, may prescribe it for another purpose.
Ask your doctor if you have any questions about why this medicine has been prescribed
As with all strong painkillers, your body may become used to you taking TARGIN tablets.
Taking it may result in physical dependence. Physical dependence means that you may

important to take it exactly as directed by your doctor.
