The Active Ingredient: Diclofenac and Its Mechanism
The primary active ingredient in all Voltaren Actigo products is diclofenac, a non-steroidal anti-inflammatory drug, or NSAID. As with other NSAIDs like ibuprofen, diclofenac works by reducing substances in the body that cause inflammation and pain. Specifically, it functions by blocking the effects of cyclooxygenase (COX) enzymes, which are responsible for the synthesis of prostaglandins. Prostaglandins are lipid compounds that elevate body temperature and make nerve endings more sensitive to pain. By inhibiting prostaglandin synthesis, diclofenac reduces inflammation and pain at the site of the issue.
There is a notable difference in how the active ingredient reaches the body depending on the formulation. With topical application (gels), a smaller amount of diclofenac is absorbed systemically into the bloodstream compared to oral tablets. The gel works by pooling diclofenac on the skin's surface, from where it penetrates the underlying tissues to target the inflamed area directly. This localized action makes the gel ideal for specific, contained injuries. Oral tablets and liquid capsules, on the other hand, provide a more systemic effect, circulating throughout the body to alleviate broader, non-localized pain.
Uses and Formulations of Voltaren Actigo
Voltaren Actigo is available in several forms, each tailored for different types of pain. Understanding the specific formulation is key to using the product effectively and safely.
Voltaren Actigo Topical Gels
-
Voltaren Actigo 1% Gel: This formula, sometimes available with a special applicator tube, is used for the short-term local treatment of minor trauma, including sprains and bruises. It is designed for adult use. The applicator allows for easy application and massage without direct contact with fingers.
-
Voltaren Actigo 2% Intense Gel: This is a more concentrated gel for muscle and joint pain, also derived from diclofenac diethylamine. It provides intense pain relief for conditions like minor trauma, sprains, and contusions. It is typically recommended for limited periods.
Voltaren ActiGo Oral Forms
-
Voltaren ActiGo Extra 25 mg Tablets: These tablets are designed for quick help with broader pain categories. Uses include back pain, headache, dental pain, and painful menstruation. They also serve to reduce swelling in post-traumatic conditions like sprains and stretched muscles. Recommended for short-term treatment in adults and adolescents over 14.
-
Voltaren Acti-Go Liquid Gelcaps: Containing diclofenac potassium per capsule, these liqui-gels are used for short-term treatment of headaches, backaches, muscular pain, rheumatic pain, menstrual pain, and fever reduction. They are also intended for use by adults and adolescents over 14 and should not be used for more than a few days.

Side Effects and Precautions for Voltaren Actigo
Although Voltaren Actigo gels and oral forms offer different safety profiles due to absorption differences, both require careful use. All NSAIDs carry some risk of side effects.
Potential Side Effects
-
For Gels: The most common adverse effects are local skin reactions, such as redness, itching, skin irritation, or peeling at the application site. A photosensitivity reaction (increased sensitivity to sunlight) can also occur.
-
For Oral Forms: Risks are higher for systemic side effects, including gastrointestinal issues like stomach pain, heartburn, constipation, or diarrhea. Serious but rarer side effects include an increased risk of heart attack or stroke, especially with long-term use or in those with risk factors. Liver and kidney problems can also occur.
Important Precautions
-
Pregnancy and Breastfeeding: Voltaren Actigo, both topical and oral, should be avoided during the third trimester of pregnancy due to potential risks to the unborn child. It is also not recommended for use during breastfeeding.
-
Allergies: Do not use if you have a known allergy to diclofenac, aspirin, or other NSAIDs. Signs of an allergic reaction include hives, difficult breathing, or facial swelling.
-
Application Guidelines for Gel: Avoid applying gel to open wounds, mucous membranes, or the eyes. Do not use occlusive (airtight) dressings or apply external heat to the treated area. After applying the gel, it is best to wash your hands unless the hands are the area being treated.
-
Underlying Health Conditions: Exercise caution and consult a healthcare provider if you have a history of asthma, allergic disease, peptic ulcer, kidney or liver failure, heart disease, high blood pressure, or a risk of bleeding.
Conclusion
Voltaren Actigo offers a versatile range of diclofenac-based products for managing different types of pain and inflammation. For localized issues like minor sprains and bruises, the topical gels (1% and 2%) provide targeted relief directly at the source. For broader, systemic pain like headaches, menstrual cramps, or general muscle aches, the oral tablets and liquid gelcaps offer a systemic solution. While topical application carries a lower risk of systemic side effects compared to oral intake, all forms of diclofenac require careful adherence to instructions and consideration of potential risks. Always choose the appropriate formulation for your specific needs, follow the usage guidelines strictly, and consult with a healthcare professional to ensure safe and effective use, especially if symptoms persist or you have underlying health conditions.
