Voltaren products contain varying amounts of diclofenac, depending on the specific formulation and intended use. For example, Voltaren Emulgel, a topical pain relief gel, typically contains 1% diclofenac diethylamine [1]. This is equivalent to 11.6 mg of diclofenac per gram of gel. For oral use, Voltaren tablets (Voltaren 25, Voltaren 50, and Voltaren 100) contain diclofenac sodium at dosages of 25 mg, 50 mg, and 100 mg, respectively [2]. Another oral formulation, Voltaren XR, is an extended-release tablet containing 100 mg of diclofenac sodium [3].
What is Diclofenac Used For?
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing substances in the body that cause pain and inflammation [4]. It is commonly used to treat pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis [5]. Topical formulations like Voltaren Emulgel are used to relieve localized pain and inflammation, such as from sprains, strains, and bruises [1].
What is the Difference Between Voltaren Emulgel and Voltaren Tablets?
The primary difference between Voltaren Emulgel and Voltaren tablets lies in their administration and intended use. Voltaren Emulgel is a topical treatment applied directly to the skin over the affected area to provide localized pain relief and reduce inflammation [1]. Voltaren tablets are oral medications taken by mouth, which deliver the drug systemically to address pain and inflammation throughout the body [2, 3].
How Long Does Diclofenac Stay in Your System?
The duration diclofenac remains in the body depends on the formulation and individual metabolism. For oral diclofenac sodium, the elimination half-life is typically around 1 to 2 hours [6]. However, extended-release formulations like Voltaren XR are designed to release the medication over a longer period, potentially affecting how long the drug is active in the system [3]. Topical absorption may also result in different systemic exposure levels compared to oral administration.
Can You Buy Voltaren Without a Prescription?
Availability of Voltaren products without a prescription varies by region and formulation. In some countries, lower-strength topical formulations of diclofenac, such as Voltaren Emulgel, are available over-the-counter [1]. However, oral formulations of diclofenac, especially higher-dose tablets and extended-release versions, are generally prescription-only medications [2, 3].
What are the Risks of Taking Diclofenac?
Like other NSAIDs, diclofenac carries potential risks. These include gastrointestinal issues such as stomach pain, nausea, ulcers, and bleeding [5, 7]. Cardiovascular risks, including heart attack and stroke, have also been associated with NSAID use, particularly with long-term therapy or in individuals with existing heart conditions [7]. Other potential side effects can include dizziness, rash, and kidney problems [5, 7].
