Voltaren Patient Tips
Medically reviewed on Dec 13, 2017 by C. Fookes, BPharm.
How it works
- Voltaren is a brand (trade) name for diclofenac.
- Diclofenac helps to relieve pain and inflammation by blocking the effects of cyclooxygenase (COX) enzymes. This prevents prostaglandin synthesis (prostaglandins elevate body temperature and make nerve endings more sensitive to pain transmission).
- Voltaren belongs to a class of medicines known as NSAIDs (nonsteroidal anti-inflammatory drugs).
- Used to relieve mild-to-moderate acute pain associated with osteoarthritis and rheumatoid arthritis.
- May also be used to relieve mild-to-moderate pain due to other causes.
- Relieves inflammation and lowers temperature.
- May also be used in the treatment of ankylosing spondylitis (a form of spinal arthritis).
- Voltaren is available as a generic under the name diclofenac.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- Water retention, headache, constipation, and nausea.
- Stomach-related side effects such as indigestion, belching, heartburn, and bleeding. People of an older age, taking other medicines that affect the stomach, or who drink more than 3 glasses of alcohol per day may be more at risk. Voltaren is more likely than ibuprofen to cause stomach-related side effects.
- Other side effects including tinnitus (ringing in the ears) have also been reported.
- Most NSAIDs have been associated with an increased risk of serious cardiovascular events including stroke or heart attack. The risk may be higher in patients with pre-existing cardiovascular conditions and with higher dosages. Voltaren may be associated with a higher risk compared with other NSAIDs, such as ibuprofen.
- May increase bleeding time especially if given with other medicines that also delay blood clotting.
- May not be suitable for some people including those with kidney disease, a history of stomach ulcers or other gastrointestinal disorders, or with pre-existing cardiovascular disease. Should not be given during or following coronary artery bypass graft surgery.
- May interact with some other medicines such as warfarin, SSRIs, ACE inhibitors, and diuretics.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Taking Voltaren with food may help with stomach-related side effects.
- May make your skin more sensitive to the sun; wear sunblock SPF 30-50+ when outside; see a doctor as soon as possible if you develop a skin rash.
- Should not be taken for for long periods of time, especially in seniors.
- Blood counts and liver enzymes may need monitoring periodically.
- NSAIDs should not be used in the last 3 months of pregnancy; always ask your doctor before using any medication during pregnancy.
- If you have experienced asthma-like symptoms, developed hives (urticaria) or other allergic-type reactions in the past after taking aspirin or other NSAIDs (like ibuprofen), do not take Voltaren.
- Combining Voltaren with alcohol may increase the risk of developing a stomach ulcer or bleeding from your stomach.
Response and Effectiveness
- Time to peak effect varies from 30 minutes to 3-5 hours depending on the formulation of diclofenac taken.
- Immediate-release tablets should be dosed two to three times daily. Extended-release tablets are usually taken once daily. Different formulations (for example enteric coated tablets and extended-release tablets) are not necessarily bioequivalent even if the milligram strength is the same.
