Teosyal

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    Routes of administration

    Intradermal injection

    Directions

    Teosyal should be administered by a licensed healthcare professional trained in dermal filler techniques. The product is injected intradermally or subcutaneously, depending on the indication and formulation. The treatment area should be cleaned and disinfected prior to injection. For patient comfort, many Teosyal formulations include lidocaine. After injection, gentle massage may be applied to ensure even distribution. Results are typically visible immediately, with optimal outcomes assessed after any initial swelling subsides.

    Ingredients

    The core ingredient in all Teosyal products is:

    • Cross-linked hyaluronic acid (concentration varies by product, typically between 15 mg/mL and 25 mg/mL)
    • Some formulations also contain lidocaine hydrochloride (0.3%) as a local anesthetic

    Other excipients may include phosphate-buffered saline for pH stability and tissue compatibility.

    Contraindications

    Teosyal is contraindicated in patients who:

    • Have a known hypersensitivity to hyaluronic acid, lidocaine, or amide-type local anesthetics
    • Have active skin infections or inflammation at the injection site
    • Are prone to hypertrophic scarring or keloid formation
    • Are pregnant or breastfeeding
    • Have autoimmune disorders or undergoing immunotherapy (unless deemed appropriate by a specialist)

    Cautions

    Teosyal should be used with caution in patients with bleeding disorders or those taking anticoagulant therapy. Avoid injection into or near blood vessels to prevent vascular complications. Patients should avoid exposure to extreme temperatures, saunas, and vigorous facial manipulation for at least one week after treatment. Temporary post-treatment swelling, redness, or bruising may occur. A full medical history should be obtained prior to treatment to assess risk factors.

    Side Effects

    Side effects are generally mild and transient, and may include:

    • Redness, swelling, or tenderness at the injection site
    • Bruising or hematoma formation
    • Itching or mild discomfort
    • Rarely, lumps or nodules
    • Very rarely, allergic reactions or vascular occlusion
