Uses
See also Warning section.
Diclofenac is used to relieve mild to moderate pain and swelling (inflammation) from various conditions such as headache, dental pain, menstrual cramps, and muscle aches. Some brands of this medication may also reduce pain, swelling, and joint stiffness from arthritis. Reducing these symptoms helps you do more of your normal daily activities.
Diclofenac is known as a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking your body's production of certain natural substances that cause inflammation. This effect helps to decrease swelling, pain, or fever.
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.
Warning
Nonsteroidal anti-inflammatory drugs (including diclofenac) may rarely increase the risk of a heart attack or stroke. This effect can happen at any time while taking this drug but is more likely if you take it for a long time. The risk may be greater in older adults or if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes). Do not take this drug right before or after heart bypass surgery (CABG).
Also, this drug may rarely cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning symptoms at any time while taking this drug. Older adults may be at higher risk for this effect.
Stop taking diclofenac and get medical help right away if you notice any of these rare but serious side effects: stomach/abdominal pain that doesn't go away, black/tarry stools, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, confusion, weakness on one side of the body, trouble speaking, sudden vision changes.
Talk to your doctor or pharmacist about the benefits and risks of taking this drug.

How to Use This Medication
Read the Medication Guide provided by your pharmacist before you start taking diclofenac and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually 2-4 times a day. Take this medication with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this medication. If stomach upset occurs while taking this medication, take it with food, milk, or an antacid.
There are different brands and forms of this medication available. Because different forms do not have the same effects at equal strengths, do not switch forms of diclofenac unless your doctor tells you to.
The dosage is based on your medical condition, response to treatment, and other medications you may be taking. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose or take this drug more often or for longer than prescribed. Discuss the risks and benefits with your doctor or pharmacist.
For certain conditions (such as arthritis), it may take up to 2 weeks of taking this drug regularly until you get the full benefit.
If you are taking 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 medicine may not work as well.
Tell your doctor if your condition gets worse.
