Voveran Gel is formulated for musculoskeletal pain and is not indicated for acne treatment. The gel’s active ingredient may irritate facial skin, especially in areas prone to oiliness, and could aggravate acne. Use a product specifically approved for dermatological conditions instead.

Topical diclofenac is not listed as a prohibited substance by most major sporting agencies, but athletes should verify current regulations with their governing body and inform the testing authority if asked.
Discontinue use immediately, wash the area with mild soap and water, and seek medical advice. A rash may indicate an allergic reaction or sensitivity to an excipient.
Applying the gel prior to exercise can reduce joint pain, but avoid covering the area with tight bandages or heated pads during the workout, as this may increase systemic absorption.
Voveran Gel is typically supplied in a 30 g or 60 g tube. The amount needed per application varies, but a 30 g tube generally provides a week’s supply when used as directed (3-4 applications daily).
Concurrent use of two NSAIDs can raise the risk of gastrointestinal bleeding and renal impairment. Discuss with a pharmacist or physician before combining them.
Do not pour the gel down the drain. Place the empty tube in a sealed bag and dispose of it with household waste according to Hong Kong’s hazardous waste guidelines, or return it to a pharmacy that offers medication take-back services.
Topical diclofenac is not recommended during pregnancy, especially in the third trimester. In early pregnancy, the safety data are limited, so a healthcare professional should evaluate the risk-benefit ratio before use.
