Important information about Voltaren SR

The active ingredient in Voltaren SR is diclofenac sodium SR. This painkiller works by inhibiting the COX enzymes, which in turn reduces the formation of prostaglandins. These prostaglandins are markers of inflammation and can cause symptoms of fever and pain. By decreasing the synthesis of prostaglandins, the symptoms of pain will be reduced.

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide, before using Voltaren SR. However, the following is a synopsis of the general guidelines for the use of Voltaren SR:

  • This medication is best taken with food to avoid stomach upsets and can be taken once a day. It is best to use the lowest effective dose for pain management.
  • If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and only take the next dose. Do not take double or extra doses.

The most common side effects of Voltaren SR include:

  • Drowsiness
  • Heartburn and gas
  • Gastrointestinal/abdominal pain
  • Diarrhea
  • Nausea
  • Constipation

Some individuals may experience serious side effects while using Voltaren SR. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

  • Heart failure and high blood pressure: shortness of breath, swelling of the ankles, feet, or hands, blurred vision, sudden weight gain, unusual weakness or fatigue
  • Stomach bleeding or perforation: vomiting blood, dark or bloody stools, and severe stomach pain
  • Severe kidney problems: fatigue, dry and itchy skin, loss of appetite, urinating less than usual, bloody urine, and muscle cramps
  • Stroke: chest pain, shortness of breath, weakness on one side of your body or face, and slurred speech
  • Severe liver problems: abdominal swelling, yellowing of your skin or eyes (jaundice), and dark urine
  • Severe allergic or skin reactions: skin rash, dermatitis, reddening, peeling, or blisters, trouble breathing

These are not all of the possible side effects of Voltaren SR. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

Before starting Voltaren SR, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including whether you have:

  • Fluid retention or edema
  • Gastrointestinal disorders, including ulcers, ulcerative colitis, or Crohn’s disease
