Voltaren, known generically as diclofenac, is a non-steroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. It works by blocking the production of prostaglandins, which are chemicals produced in the body that promote inflammation. Voltaren is available as tablets, gel, and patches that can be applied directly to the skin.
How is Voltaren absorbed?
The speed at which Voltaren starts working depends on the dosage form:
- Tablets need to dissolve in the stomach before the active ingredient diclofenac is absorbed into the bloodstream. This can take 30-60 minutes.
- Gels and creams containing diclofenac are applied directly to the skin over the painful area. From there, diclofenac is absorbed through the skin into underlying tissues. This provides more immediate pain relief usually within 10-15 minutes.
- Patches containing diclofenac work the same way as the gels. By delivering the medicine right to the source of pain, patches can begin working within 30 minutes.
Therefore, Voltaren gel, cream, and patch formulations tend to provide faster pain relief than tablets because they don’t have to go through the digestive system first.
How does diclofenac treat pain?
Once absorbed and circulating in the bloodstream, diclofenac works by:
- Inhibiting COX enzymes – these enzymes normally produce prostaglandins which promote inflammation and sensitize pain receptors. By blocking COX enzymes, fewer prostaglandins are made, reducing inflammation and sensitivity to pain.
- Reducing nerve impulses – diclofenac also acts directly on nerves in tissues to decrease the number of pain signals being transmitted to the brain.
Together, these effects of diclofenac provide rapid relief of pain and swelling.
What conditions does Voltaren treat?
Voltaren is approved to treat a variety of acute and chronic pain conditions including:
- Arthritis – osteoarthritis, rheumatoid arthritis
- Musculoskeletal injuries – sprains, strains, sports injuries
- Soft tissue disorders – tendonitis, bursitis
- Menstrual cramps
- Migraines and headaches
- Toothache
- Lower back pain
For many of these conditions, using a topical gel or patch can bring relief within minutes to hours after the first application. Tablets take longer to work but provide extended pain relief for up to 8 hours.
How long does it take for Voltaren to work?
Here’s a summary of how fast Voltaren may start working based on the formulation:
| Voltaren Form | Onset of Pain Relief |
|---|---|
| Tablets | 30-60 minutes |
| Gel/cream | 10-15 minutes |
| Patches | 30 minutes |
Keep in mind that exact timing can vary between individuals based on factors like:
- Severity of pain/inflammation
- Application site – gels/patches work faster when applied directly over the painful area
- Dose taken
- Age and metabolism
- Whether taken with food – can delay absorption of tablets
Talk to your doctor about what to expect with Voltaren and when you should start to experience pain relief.
Tips for faster relief
Here are some tips to help Voltaren work as fast as possible:
- Use topical gels or patches instead of tablets when possible – gets diclofenac directly to the source of pain.
- Take tablets on an empty stomach with a full glass of water – avoids delays in absorption.
- Apply gels/patches to clean skin free of lotions or oils – allows diclofenac to penetrate optimally.
- Use the gel or patch as directed several times a day – maintains therapeutic diclofenac levels.
- Try a higher dose – under medical supervision, increased doses provide more pain relief.
- Use Voltaren along with rest, ice, compression to manage swelling.
- Give it time to work – may take over an hour for maximal effects.
How long do the effects last?
Diclofenac remains active in the body for several hours. The pain-relieving effects of Voltaren can last:
- Tablets – 6 to 8 hours
- Gel – 4 to 6 hours
- Patches – up to 12 hours
Reapplication allows ongoing pain control with gels and patches. Tablets can be taken on a regular schedule such as every 6-8 hours. Don’t exceed prescribed dosage limits.
Conclusion
Voltaren is a fast-acting NSAID because formulations like gels and patches allow the medicine diclofenac to be rapidly absorbed through the skin at the site of pain. Tablets take effect more slowly as they need to be processed through the digestive system first. However, Voltaren tablets last longer in the body, providing up to 8 hours of relief with a single dose. Using Voltaren as directed can provide effective relief for minor aches and pains within 30 minutes to 1 hour.
