What Indometacin suppositories are and what they are used for

Indometacin suppositories belong to a group of medicines called non-steroidal anti-inflammatory
drugs (NSAIDs). These medicines are pain killers which reduce swelling.
Indometacin suppositories are for:
• inflammatory diseases of the joints such as rheumatoid arthritis, osteoarthritis and degenerative
hip disease
• pain and stiffness in the backbone (ankylosing spondylitis)
• sprains and strains (acute muscle and bone disorders)
• lower back pain
• pain and swelling following muscle or bone surgery
• period pain
• gout.


Before you use Indometacin suppositories

Do not use Indometacin suppositories if you:
• are in the last three months of pregnancy
• are allergic (hypersensitive) to indometacin or any of the ingredients of Indometacin
suppositories (see section 6)
• are allergic (hypersensitive) to aspirin, ibuprofen or other NSAIDs or you have developed signs
of asthma (wheezing), runny nose, swelling of the face, lips, tongue or throat or a skin rash with
pale or red irregular raised patches with severe itching, when taking these medicines
• are taking other NSAIDs (e.g. Naproxen) or COX II inhibitors (e.g. Celecoxib)
• suffer with angioneurotic oedema (swelling of the face, lips, tongue or throat)
• have or have had a history of two or more episodes of peptic ulcer (ulcer in your stomach or
duodenum) or bleeding in your stomach or intestines in the past. Symptoms may include
vomiting particles that look like coffee-grounds, black tarry stools and blood in your faeces
• have severe liver, kidney or heart problems
• have had bleeding in your stomach or intestines or perforation after taking NSAIDs
• have nasal obstruction (nasal polyps)
• have piles (haemorrhoids) or inflammation or bleeding of the back passage.
Indometacin suppositories must not be used in children.

Check with your doctor before using Indometacin suppositories if you are:

elderly (see “Other warnings”)
to have a vaccination with a live vaccine

a woman trying to become pregnant or undergoing investigation for infertility. Indometacin
may make it more difficult to become pregnant. You should inform your doctor if you are
planning to become pregnant or if you have problems becoming pregnant
taking a medicine which is poisonous to the kidneys such as cisplatin or vancomycin.

or if you have:

a history of high blood pressure or congestive heart failure
a bleeding or blood clotting disorder
mental health problems e.g. mood changes
Parkinson’s Disease (tremor, stiffness and shuffling)
any infection or sepsis (severe infection)
any liver, kidney or heart problems
fluid retention which may be caused by diseases of the heart or kidneys
asthma or a history of asthma
have or have a history of gastrointestinal diseases such as ulcerative colitis or Crohns disease
systemic lupus erythematosus (SLE) or other connective tissue disorders
a decreased amount of fluid around the cells of the body (extracellular volume depletion)
peripheral arterial disease (a problem with the circulation in the legs).

Other warnings
If you are elderly or you have previously had stomach ulcers, you have a higher risk of getting
side effects, especially from the stomach. Your doctor should therefore prescribe the lowest dose
that gives you sufficient relief. If you experience any unusual symptoms from the stomach, you must
tell your doctor about it.
Medicines such as indometacin may be associated with a small increased risk of heart attack
(“myocardial infarction”) or stroke. Any risk is more likely with high doses and prolonged
treatment. Do not exceed the recommended dose or duration of treatment.
If you have heart problems, previous stroke or think that you might be at risk of these conditions
(for example if you have high blood pressure, diabetes or high cholesterol or are a smoker) you
should discuss your treatment with your doctor or pharmacist.
Taking painkillers for headaches too often or for too long can make them worse.

Taking other medicines
Please tell your doctor or pharmacist if you are taking, or have recently taken, any other medicines,
including medicines obtained without a prescription, particularly:
• other non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin, naproxen or COX II
inhibitors (e.g. celecoxib) or diflunisal (for pain and inflammation)
• quinolone antibiotics e.g. ciprofloxacin (to treat infections)
• medicines which thin the blood or which prevent blood clotting, such as warfarin or antiplatelet
drugs such as clopidogrel
• selective serotonin reuptake inhibitors (SSRIs) e.g. fluoxetine (for depression)
• metformin or sulphonylureas e.g. gliclazide (for diabetes)
• phenytoin (for epilepsy)
• diazepam (for anxiety, difficulty sleeping, alcohol withdrawal, seizures and muscle spasm)
• medicines used to treat high blood pressure such as beta blockers (e.g. atenolol), alpha blockers
(e.g. prazosin), ACE inhibitors (e.g. lisinopril), angiotensin II receptor antagonists (e.g.
valsartan), hydralazine (vasodilator) or nifedipine
• haloperidol (an antipsychotic drug)
• zalcitabine, zidovudine or ritonavir (for HIV infection)
• cardiac glycosides e.g. digoxin (for heart failure and irregular heart beat)
• ciclosporin, tacrolimus or muromonab-CD3 (to suppress the immune system)
• corticosteriods e.g. prednisolone (used in many different diseases)

cyclophosphamide or methotrexate (to treat some types of cancer, psoriasis or rheumatoid
desmopressin (for diabetes insipidus and frequent urination during the night)
diuretics (water tablets) such as triamterene, thiazides (e.g. bendroflumethiazide) or
lithium (for some mental health problems)
mifepristone (used for termination of pregnancy). Indometacin suppositories should not be used
within 8-12 days of taking mifepristone
baclofen (a muscle relaxant)
pentoxifylline (for blood vessel disease and leg ulcers)
probenecid (for gout)
tiludronic acid (for Paget’s disease of bone).

Your doctor may want to carry out tests to monitor your kidney and liver function, the levels of
blood cells and the effects on your stomach and intestines (especially if you are elderly). If you have
or have had a history of high blood pressure or heart failure, your doctor may also want to monitor
you. If you have rheumatoid arthritis you may be advised to have regular eye tests to check your
