Indications
Linseed oil (flaxseed oil) comes from the seeds of the flax plant. In medicines it is mainly used as an ingredient in topical pain-relief gels and sprays, usually combined with a pain reliever such as Diclofenac and with warming or cooling agents such as Methyl salicylate and Menthol. These products are used for short-term relief of muscle pain, sprains, strains, back pain, stiff neck and mild joint pain.
How It Works
Linseed oil is rich in alpha-linolenic acid, an omega-3 fatty acid with mild anti-inflammatory properties. In a gel it also softens the skin and is thought to help the other active ingredients spread and pass into the skin. The main pain relief in combination products comes from the anti-inflammatory medicine and the counter-irritants.
Dosage and Administration
Use as directed on the label. Usually a small amount of gel, or a few sprays, is gently rubbed into the painful area 3 to 4 times a day. Wash your hands afterwards unless the hands are being treated. Do not use for more than 7 to 14 days without medical advice. For external use only.
Interactions
Using these products on large areas for long periods together with pain tablets of the same type (for example Ibuprofen, Naproxen, Aspirin) or blood thinners such as Warfarin may increase side effects. Avoid using other skin products on the same area at the same time.
Contraindications
- Allergy to linseed (flax) or any ingredient
- Allergy or asthma triggered by Aspirin or other anti-inflammatory painkillers (for combination products)
- Broken, infected or eczema-affected skin, eyes and mucous membranes
- Last 3 months of pregnancy (for products containing Diclofenac or salicylates)
Side Effects
Possible effects include redness, itching, warmth, burning or a rash where it is applied. Skin may become more sensitive to sunlight with some ingredients.
Get urgent medical help if you have wheezing or difficulty breathing, swelling of the face or lips, or a severe or blistering rash after use.
Pregnancy and Lactation
Do not use combination products containing Diclofenac or salicylates in the last 3 months of pregnancy, and ask your doctor before using them earlier in pregnancy. During breastfeeding, use only on small areas for a short time and never on the breasts.
Precautions and Warnings
Do not cover with tight bandages or use with a heating pad. Avoid strong sunlight on treated skin. Keep away from eyes. Not for children unless the label allows it. See a doctor if pain lasts more than a week or there is swelling, redness or fever.
Overdose
Overuse on the skin may increase local irritation. If swallowed, especially by a child, contact a doctor or poison centre, as salicylate-containing products can be harmful.
Therapeutic Class
Topical analgesic ingredient (plant oil, used in pain-relief preparations).
Storage
