Let's take a minute to talk about your medication.

This is Diclofenac. It is a type of pain reliever known as an "NSAID". "NSAID" stands for Non-Steroidal Anti-Inflammatory Drug. It helps to treat pain and swelling from different medical conditions, such as arthritis or short-term injuries. It may have other uses, too. 

You should take diclofenac exactly as your doctor tells you to. Your healthcare team will determine the best dose for you and how long you should take this medication. Call your doctor if your dose does not control your pain. You should not change your dose unless your doctor says it's okay. 

Most patients tolerate this medicine well. Common side effects include nausea, vomiting, diarrhea, and stomach pain. It can also cause heartburn, gas, or constipation. These effects are normal if they are mild and should go away. If these or other side effects become reasons you want to stop taking this medication, please talk to your healthcare team. 
As with any medicine, rare but more serious side effects could occur. With Diclofenac, this includes an increased risk of heart attack or stroke. It can also cause serious and sudden bleeding or sores in the digestive tract, often in the stomach. You should read the medication guide to know which symptoms to watch for, and when to report changes. 
Diclofenac can interact with other medicines. You should check with your doctor or pharmacist before taking any other medicines, herbal remedies, or vitamins. 
Women must check with their doctors before becoming pregnant or breastfeeding while taking this medication. You should not take Diclofenac after 29 weeks of pregnancy.

For best results with Diclofenac, work with your doctor to use the lowest dose for the shortest time possible.
