Indications
Hyaluronic Acid is a natural substance found in joint fluid, skin and the eye. In Bangladesh it is mostly sold as an oral supplement, often combined with Glucosamine, Chondroitin or Collagen, to support joint comfort and mobility in people with osteoarthritis (wear-and-tear arthritis). It is also used in skin-care products for hydration, in eye drops for dry eyes, and as an injection into the knee joint given by a doctor.
How It Works
Hyaluronic Acid holds large amounts of water and makes joint fluid thick and slippery, which helps cushion and lubricate the joint. When taken by mouth it is thought to support the body’s own joint tissues, although the benefit is modest and varies between people. On the skin and eye surface it attracts and holds moisture.
Dosage and Administration
Oral supplements: take as directed on the label, usually once or twice daily with food. Joint benefits, if any, usually take several weeks to appear.
Eye drops and skin products: use as directed on the label. Injections into the joint are given only by a doctor, as prescribed.
Interactions
No important interactions are known for oral or topical Hyaluronic Acid. Combination products may contain Glucosamine, which can affect the action of Warfarin, so tell your doctor if you take a blood thinner.
Contraindications
Do not use if you are allergic to Hyaluronic Acid or any ingredient of the product. Joint injections should not be given into an infected joint or through infected skin.
Side Effects
- Oral: mild stomach upset or bloating, uncommon.
- Eye drops: brief blurred vision or stinging.
- Joint injection: temporary pain, swelling or warmth in the joint.
Get urgent medical help if you notice signs of a serious allergic reaction such as rash, swelling of the face or throat, or difficulty breathing, or if an injected joint becomes very hot, red and painful with fever.
Pregnancy and Lactation
Topical and eye products are generally considered safe. There is limited information on oral supplements in pregnancy and breastfeeding, so ask your doctor before using them.
Precautions and Warnings
Supplements do not replace treatment prescribed for arthritis. If you have a shellfish allergy, check whether a combination product contains Glucosamine made from shellfish. People with diabetes should check the label of combination products for sugar content.
Overdose
Taking too much by mouth is unlikely to be harmful but may cause stomach upset. Contact a doctor if you feel unwell.
