The Science Behind Voltaren Gel
Voltaren gel contains the active ingredient diclofenac sodium, a nonsteroidal anti-inflammatory drug (NSAID). Unlike oral NSAIDs that circulate throughout the body, Voltaren is designed to deliver targeted pain relief by penetrating the skin at the site of inflammation. It works by inhibiting the production of prostaglandins, which are responsible for causing pain and inflammation.
Voltaren's 'Emulgel' formulation is key to its effectiveness. This technology combines the properties of a gel and a cream, allowing the diclofenac to penetrate deeply into the skin's surface. Once there, it creates a reservoir of medication in the skin's outer layers, which then provides a sustained release of the drug to the underlying painful tissue or joint. Proper application, including the act of rubbing it in, is vital for activating this process and ensuring the medication reaches its intended target.
How to Apply Voltaren Gel: Step-by-Step
Following the manufacturer's instructions is crucial for the safe and effective use of Voltaren gel. Here is a step-by-step guide to proper application:
- Wash your hands: Begin by washing and drying your hands thoroughly before handling the gel.
- Use the dosing card: Always use the dosing card provided in the package to measure the correct amount of gel for the affected area.
- Apply and rub: Squeeze the measured gel onto the dosing card or directly onto the clean, dry skin of the affected area. Then, use your hand to gently and slowly rub the gel into the skin until it is fully absorbed. The rubbing motion helps the Emulgel technology penetrate the skin more effectively.
- Wash your hands again: After application, wash your hands thoroughly unless the treated area is your hands. If treating your hands, wait at least one hour before washing them.
- Wait to cover: Do not cover the treated area with clothing, gloves, or bandages for at least 10 minutes to allow the gel to dry and absorb. Avoid showering or bathing for at least one hour after application.
The Importance of Rubbing Gently
The action of gently rubbing Voltaren gel into the skin is not merely a formality. It is a critical part of the process that facilitates the gel's effectiveness. This mechanical action helps to disperse the medication evenly over the entire treatment area, ensuring that the active ingredient, diclofenac, is delivered directly to the inflamed tissue. The gentle massage can also have a soothing effect on the painful area, contributing to the overall pain relief experience. It is important to remember that 'gently' is the key term here—there is no need for a vigorous or painful massage, as this will not improve absorption and could cause irritation.
Common Mistakes to Avoid
To ensure you get the most out of your Voltaren gel and avoid unnecessary side effects, be aware of these common application errors:
- Applying too much gel: Using more gel than indicated on the dosing card is not recommended and can increase the risk of side effects. Stick to the measured dose.
- Using on broken skin: Never apply the gel to open wounds, cuts, infections, or irritated skin. This can cause severe irritation and increase systemic absorption of the medication.
- Skipping the dosing card: The dosing card is provided for a reason. Ignoring it can lead to inaccurate dosing, reducing effectiveness or increasing side effects.
- Forgetting to wash hands: Not washing your hands after application can lead to accidental transfer of the gel to sensitive areas like your eyes, nose, or mouth.
- Covering with a bandage or heat: Using occlusive dressings (like airtight bandages) or external heat sources (like heating pads) over the treated area is not recommended. This can significantly increase the amount of medication absorbed, raising the risk of adverse effects.
Comparison: Oral vs. Topical Diclofenac
While Voltaren gel and oral diclofenac tablets both contain the same active ingredient, their delivery methods and effects on the body differ significantly.
| Aspect | Topical (Voltaren Gel) | Oral (Diclofenac Tablets) |
|---|---|---|
| Systemic Absorption | Very low; only about 6% is absorbed into the bloodstream. | High; the entire dose is absorbed into the bloodstream. |
| Gastrointestinal (GI) Side Effects | Minimal risk of GI side effects like ulcers or bleeding, as absorption is low. | Increased risk of GI side effects, especially with long-term use. |
| Targeted Pain Relief | Delivers medicine directly to the affected tissue underlying the treated area. | Medication is distributed throughout the body via the bloodstream, potentially affecting other organs. |
| Convenience | Applied directly to the painful area, with specific dosing based on the area. | Requires ingestion, with dosage depending on the specific product and condition. |
When to Consult a Doctor
Voltaren gel is intended for temporary pain relief. If your arthritis pain does not improve after 7 days of regular use, you should stop using the product and consult a healthcare provider. You should also seek medical advice if you have pre-existing conditions such as heart, kidney, or liver disease, as NSAIDs carry certain risks. Additionally, never use Voltaren gel if you have recently had heart surgery, as this can increase your risk of heart attack or stroke.
Conclusion
The verdict on whether Voltaren gel should be rubbed in is clear: yes, it should be. The process of gently massaging the gel into the skin is a manufacturer-recommended step that is essential for proper absorption and targeted pain relief. By following the correct application guidelines—measuring with the dosing card, rubbing gently, and avoiding common mistakes—you can ensure the diclofenac reaches the source of your pain effectively and safely. Always consult with a healthcare provider if your pain persists or if you have any concerns about your health conditions in relation to using this product.
