Voltaren is an OTC non-steroidal anti-inflammatory medication used for topical pain relief. It is commonly applied for arthritis pain relief but may also be used for joint inflammation caused by minor injury. The active ingredient in Voltaren Emulgel – Diclofenac – works by suppressing the production of prostaglandins, which are pain-signaling chemicals. Voltaren gel is formulated to penetrate deep into the skin and it often provides better pain relief from arthritis than oral NSAID medications like Ibuprofen, Naproxen, or oral Diclofenac.
Directions
Apply a moderate amount (roughly the diameter of a nickel) of Voltaren gel onto the skin at the site of pain and use 2 fingers to spread it out evenly directly over the area where pain is radiating. Increase the amount if pain is severe or pain relief is insufficient with a standard application.
You can apply Voltaren up to 4 times per day as needed.
Wash hands after applying Voltaren to your skin.
Ingredients
The active ingredient in Voltaren gel is Diclofenac.
Cautions
For topical use on skin only, do not apply elsewhere on body and keep away from eyes, mouth, nose, and other orifices.
Use of Voltaren Emulgel may not be appropriate if you have a history of heart disease, high blood pressure, ulcers, liver or kidney disease, asthma, or if you are smoker. Speak with a doctor if you have any of these concerns.
Anyone under the age of 18 should get a doctor's approval before using Voltaren gel.
Excessive use of Diclofenac can affect ovulation for women.
Voltaren Emulgel should be stored at 68-77°F (20-25°C) and kept out of reach of children.
Reading product label for additional safety information is recommended.
Interactions
Negative drug interactions between Voltaren and other pain relieve medications may be possible, and if you are taking other Rx or OTC medications regularly it may be advisable to speak with a doctor or medical health professional to be assured that using Voltaren will not put you at risk for any such interactions.
Side Effects
Voltaren side effects are uncommon, but some users may experience skin reddening, blisters, facial swelling, shock, rash, or worsened asthma. If side effects are seen you may want to discontinue use and speak to a medical health professional to discuss arthritis pain relief gel alternatives.
