Diclofenac suppositories are used to relieve pain, swelling (inflammation), and joint stiffness caused by arthritis. Diclofenac does not cure arthritis, but reducing the symptoms helps you do more of your normal daily activities. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID).

If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used for other painful conditions (such as gout attacks). Consult your doctor or pharmacist for more details.

Read the Patient Information Leaflet if available from your pharmacist before you start using diclofenac and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Unwrap and insert 1 suppository into the rectum as directed by your doctor. Lie down on your left side with right knee bent. Gently push the suppository into the rectum with your finger. Remain lying down for a few minutes, and avoid having a bowel movement for an hour or longer so the drug will be absorbed. The suppository is for use in the rectum only. Wash your hands after use.

The dosage is based on your medical condition and response to treatment. Do not use more than 100 milligrams of diclofenac (suppositories and/or tablets) in a 24-hour period. To reduce your risk of stomach bleeding and other side effects, use this medication at the lowest effective dose for the shortest possible time. Do not increase your dose or use this drug more often or for longer than prescribed. For ongoing conditions such as arthritis, keep using it as directed. Discuss the risks and benefits with your doctor or pharmacist.

For certain conditions (such as arthritis), it may take up to 2 weeks of using this drug regularly until you get the full benefit.

If you are using this drug "as needed" (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.

Tell your doctor if your condition gets worse or if your pain is not controlled.

Kidney problems can sometimes occur with the use of NSAID medications, including diclofenac. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Talk to your doctor if you are using marijuana (cannabis).

This medicine may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, increases your risk for stomach bleeding. Limit alcohol and stop smoking. Ask your doctor or pharmacist about how much alcohol you may safely drink.

This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.

Older adults may be at greater risk for stomach/intestinal bleeding, kidney problems, heart attack, and stroke while using this drug.

Before using this medication, women of childbearing age should talk with their doctor(s) about the benefits and risks. Tell your doctor if you are pregnant or if you plan to become pregnant. This medication may harm an unborn baby and cause problems with normal labor/delivery. It is not recommended for use in pregnancy from 20 weeks until delivery. If your doctor decides that you need to use this medication between 20 and 30 weeks of pregnancy, you should use the lowest effective dose for the shortest possible time.

This medication passes into breast milk, but is unlikely to harm a nursing infant. Consult your doctor before breastfeeding.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include:

• aliskiren
• ACE inhibitors (such as captopril, lisinopril)
• angiotensin II receptor blockers (such as losartan, valsartan)
• cidofovir
• corticosteroids (such as dexamethasone, prednisone)
• lithium
• methotrexate
• "water pills" (diuretics such as furosemide)

This medication may increase the risk of bleeding when used with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as celecoxib, ibuprofen, ketorolac). These drugs are similar to diclofenac and may increase your risk of side effects if taken together. However, if your doctor has told you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should keep taking the aspirin unless your doctor tells you not to. Ask your doctor or pharmacist for more details.
