Voltaren Emulgel (diclofenac diethylamine) can cause side effects, although most are mild and affect the skin where the gel is applied. Because Voltaren is applied topically, systemic side effects are generally less common than with oral diclofenac.
Common side effects
-
Redness at the application site
-
Itching
-
Mild burning or stinging
-
Skin irritation or rash
-
Dry or flaky skin
-
Eczema or contact dermatitis
These reactions are usually mild and temporary. However, stop using Voltaren Emulgel if a skin rash develops and consult your healthcare provider.
Rare but serious side effects
Although uncommon, Voltaren Emulgel may cause:
-
Severe allergic reactions: Hives, swelling of the face, lips, tongue, or throat.
-
Breathing difficulties: Wheezing, shortness of breath, or chest tightness.
-
Severe skin reactions: Blistering or significant inflammation.
-
Sun sensitivity: Increased sensitivity to sunlight, potentially causing sunburn, itching, swelling, or blistering.
Stop using the medication and seek emergency medical attention if you experience breathing difficulties or swelling of the face or throat.
Precautions to reduce side effects
Apply Voltaren Emulgel only to intact skin, avoiding open wounds, irritated areas, and the eyes. Do not apply more than the recommended amount or cover the treated area with airtight bandages.
Although systemic absorption is relatively low, using excessive quantities or applying it over large areas for prolonged periods can increase the risk of NSAID-related complications, including gastrointestinal bleeding and kidney problems.
Important: Consult your healthcare provider before using Voltaren Emulgel if you have a history of stomach ulcers, kidney disease, heart problems, or are taking other NSAIDs, such as ibuprofen or naproxen.
