The active ingredient of Voltaren Rapid is diclofenac, a nonsteroidal anti inflammatory drug (NSAID).

Dose advice

Dose information:

  • Follow all the directions given to you by your doctor and pharmacist. Do not use Voltaren Rapid tablets for a longer period than your doctor recommends.
  • Swallow the tablets whole with a full glass of water. Do not crush or chew them, as this will destroy the coating of the tablets which prevents them from dissolving until they have passed through the stomach.
  • The tablets work more quickly if taken on an empty stomach, hence it is preferable to take them before meals. However, if the tablets upset the stomach, they may be taken with or soon after food.
