- In joint injections, hyaluronic acid acts as a lubricant and shock absorber, reducing pain and inflammation associated with conditions like osteoarthritis.
PHARMACOKINETICS (PK) AND PHARMACODYNAMICS (PD):
- After topical application, hyaluronic acid penetrates the skin and binds to water molecules, hydrating the skin and improving its elasticity.
- When administered orally, hyaluronic acid is broken down in the digestive tract, and its components are absorbed into the bloodstream.
- Injections of hyaluronic acid into joints provide immediate lubrication and cushioning, reducing pain and inflammation.
PATHOPHYSIOLOGY:
- Hyaluronic acid plays a crucial role in maintaining the structure and function of tissues in the body, including the skin, joints, and eyes.
- In skin, it helps retain moisture, improves elasticity, and promotes wound healing.
- In joints, hyaluronic acid provides lubrication and shock absorption, reducing friction and inflammation.

Medication Information and Guidelines
| Purpose of Taking Hyaluronic Acid: Hyaluronic acid is commonly used for skincare purposes to moisturize the skin, reduce the appearance of wrinkles, and improve skin elasticity. In medical settings, hyaluronic acid injections are used to treat joint conditions such as osteoarthritis by providing lubrication and cushioning to the affected joints. How to Use Hyaluronic Acid: For skincare, topical hyaluronic acid products like creams or serums are applied directly to clean skin, typically in the morning and evening. Injectable hyaluronic acid is administered by a healthcare professional through targeted injections into the affected joints. Oral supplements of hyaluronic acid are taken with water according to the dosage instructions provided by a healthcare provider. Other Uses of Hyaluronic Acid: Besides skincare and joint treatments, hyaluronic acid has applications in eye surgeries, wound healing, and as a component in certain medical devices like urinary catheters. Specific Precautions: Individuals with known allergies to hyaluronic acid or any of its components should avoid using products containing this ingredient. Caution is advised when using injectable hyaluronic acid in patients with active skin infections or inflammation at the injection site. Dietary Changes: No specific dietary changes are typically required while using hyaluronic acid for skincare or joint treatments. Missed Dose: If a dose of hyaluronic acid is missed, it is generally safe to resume the regular dosing schedule without doubling up on doses. Possible Side Effects: Common side effects of topical hyaluronic acid may include skin irritation, redness, or itching at the application site. Side effects of injectable hyaluronic acid may include temporary swelling, bruising, or pain at the injection site. Serious allergic reactions are rare but possible, especially in individuals with a history of allergies. Storage and Disposal: Store hyaluronic acid skincare products according to the manufacturer’s instructions, typically in a cool, dry place away from direct sunlight. Injectable hyaluronic acid should be stored as directed by the healthcare provider or pharmacist, usually in a controlled environment. Dispose of unused or expired hyaluronic acid products properly according to local regulations for medication disposal. What to Do in Case of Overdose or Emergency: In case of overdose or adverse reactions, seek medical attention immediately. If experiencing severe allergic symptoms such as difficulty breathing, swelling of the face or throat, or rapid heartbeat, call emergency services or go to the nearest emergency room. PRECAUTIONS, MONITORING AND LABORATORY TESTS: Precautions: Individuals with a history of allergic reactions should exercise caution and perform a patch test before using new skincare products containing hyaluronic acid. Monitoring: Regular monitoring by a healthcare professional may be necessary for patients receiving injectable hyaluronic acid treatments to assess efficacy and monitor for any adverse reactions. Laboratory Tests: Routine laboratory tests are typically not required for individuals using topical or oral hyaluronic acid products. However, patients undergoing injectable treatments may require periodic joint assessments and imaging studies to evaluate treatment outcomes and joint health. |
