Dorsiflex (Etofenamate)

Dorsiflex is indicated for the topical management of several painful or inflammatory musculoskeletal conditions.

• Relief of mild to moderate muscle aches and strains.
• Treatment of joint pain related to osteoarthritis or rheumatoid arthritis.
• Management of tendonitis and bursitis symptoms.
• Support for sports‑related injuries such as sprains or contusions.
• Adjunct therapy for postoperative or trauma‑induced inflammation when systemic NSAIDs are not preferred.
• Application for localized back pain or neck stiffness where oral NSAIDs may cause gastrointestinal concerns.
• Use in chronic inflammatory conditions such as ankylosing spondylitis when topical therapy is appropriate.

Topical etofenamate may cause skin‑related and systemic effects; the frequency and severity vary among individuals. These effects are generally reversible after discontinuation, but any unexpected reaction should be reported to a healthcare professional.

Common

• Local skin irritation or erythema at the application site.
• Pruritus or mild itching.
• Dryness or peeling of the treated skin.
• Sensation of warmth or burning.
• Mild swelling or edema at the site.
• Temporary discoloration or hyperpigmentation.

Serious

• Allergic contact dermatitis with vesicles or swelling.
• Severe skin ulceration or necrosis.
• Systemic hypersensitivity reactions such as urticaria.
• Signs of systemic NSAID toxicity (e.g., gastrointestinal bleeding, renal impairment).
• Stevens‑Johnson syndrome or toxic epidermal necrolysis (very rare).

When using Dorsiflex, certain precautions help minimize risks and ensure appropriate use.

• Avoid applying to broken, infected, or severely inflamed skin.
• Do not use under occlusive dressings unless directed by a clinician.
• Limit the amount and frequency according to product labeling to reduce systemic absorption.
• Keep the product away from eyes, mucous membranes, and open wounds.
• Discontinue use and seek medical advice if a rash or severe irritation develops.
• Pregnant or breastfeeding individuals should consult a healthcare provider before use.
• Patients with known NSAID hypersensitivity should avoid topical etofenamate.

Topical etofenamate can interact with other medications or substances; awareness of these interactions supports safe therapy.

Avoid

• Concurrent use of systemic NSAIDs or COX‑2 inhibitors, which may increase overall prostaglandin inhibition.
• Application together with other topical analgesics containing NSAIDs, to prevent additive local effects.
• Avoid simultaneous use with topical products containing alcohol or solvents that may increase skin irritation.

Use with caution

• Anticoagulants or antiplatelet agents, as systemic absorption could modestly affect bleeding risk.
• Corticosteroid creams applied to the same area, which may alter skin integrity.
• Herbal or over‑the‑counter products that sensitize the skin, such as menthol or capsaicin preparations.
• Patients on diuretics should monitor renal function, because systemic NSAID absorption could affect kidney handling.
