Reparil Gel combines diethylamine salicylate with aescin, a horse chestnut extract. It is rubbed into the skin for bruises, sprains, strains, swelling and superficial vein problems. It is a general-sale product, applied topically, and it works locally rather than throughout the body.
What is Reparil?
Reparil is registered in South Africa as a Schedule 1 gel:
| Contains | Per 100 g |
|---|---|
| Diethylamine salicylate | 5 g |
| Aescin (escin) | 1 g |
Two ingredients doing different jobs, which is the point of combining them.
Diethylamine salicylate is a topical salicylate — chemically related to aspirin. Absorbed through the skin, it acts locally as a mild anti-inflammatory and pain reliever. It also produces a gentle warming or counter-irritant sensation.
Aescin is the active component of horse chestnut seed extract, and it is the more interesting half. Aescin acts on capillary walls, reducing their leakiness. When you bruise or sprain something, small vessels leak fluid into the surrounding tissue — that is the swelling. Aescin reduces that leakage, which is why the combination is aimed at swelling and bruising rather than at pain alone.
That focus on swelling is what distinguishes Reparil from an ordinary topical anti-inflammatory gel such as diclofenac. A diclofenac gel targets inflammatory pain in a joint or muscle; Reparil is aimed at the fluid and blood accumulating after a knock.
Aescin taken by mouth has reasonable evidence in chronic venous insufficiency — the aching, heavy, swollen legs of poor vein circulation. Evidence for topical application is weaker, though it is widely used.
Being a gel, very little is absorbed into the body, so it avoids the stomach, kidney and heart risks of oral anti-inflammatories. That is its main practical advantage.
What is Reparil commonly used for?
- Bruises and haematomas, including after a knock or minor injury.
- Sprains and strains, particularly ankles and wrists.
- Soft-tissue swelling after injury.
- Sports injuries, for local swelling and discomfort.
- Swelling after minor surgery or dental procedures, where advised.
- Superficial thrombophlebitis, inflammation of a vein just under the skin.
- Varicose vein discomfort and tired, heavy legs.
- Insect bites and localised swelling.
It treats the local swelling and discomfort, not an underlying cause. For a significant injury, the assessment matters more than the gel.
For an acute injury, the basics do more than any gel. Rest, ice, compression and elevation in the first 48 hours reduce swelling more effectively than a topical product, and gentle movement thereafter aids recovery. Reparil is a useful addition to those, not a replacement.
How Reparil fits into this medicine category
| Group | Examples | Role |
|---|---|---|
| Topical salicylate + aescin | Reparil | Bruising, swelling, superficial vein problems |
| Topical NSAIDs | Diclofenac gel, indomethacin gel | Local joint and muscle inflammation |
| Counter-irritants | Methyl salicylate, camphor, menthol rubs | Warming or cooling sensation |
| Oral NSAIDs | Ibuprofen, naproxen | Pain and inflammation throughout the body |
| Simple analgesics | Paracetamol | Pain and fever |
| Corticosteroids | Prednisone | Powerful anti-inflammatory, as courses |
Topical products in general are a sensible option for people who should avoid oral anti-inflammatories — those with stomach, kidney or heart concerns — since systemic exposure is far lower. See the pain, inflammation and musculoskeletal medicines hub.
What to check before using Reparil
Apply only to intact skin. Do not use it on broken skin, open wounds, grazes, or areas of eczema or dermatitis. Salicylates are absorbed far more readily through damaged skin.
Keep it away from the eyes, mouth and mucous membranes, and wash your hands after applying unless you are treating your hands.
Do not cover it with an airtight dressing unless advised, as this increases absorption.
Speak to a pharmacist or doctor first if you:
- Are allergic to aspirin or salicylates, or have had wheezing or a reaction to aspirin or NSAIDs. Salicylates absorbed through the skin can trigger the same reaction.
- Have asthma, particularly aspirin-sensitive asthma.
- Are using it on a child. Salicylate-containing products are generally avoided in children because of the association between salicylates and Reye’s syndrome — ask a pharmacist before using it on anyone under 16.
- Are pregnant or breastfeeding. Avoid applying it to the breast area before feeding.
- Take warfarin or another blood thinner, where absorbed salicylate could add to bleeding risk.
- Are applying it to large areas, or using it frequently over a long period.
- Have kidney disease.
- Have sensitive skin, in which case test a small area first.
A note on the horse chestnut component: if you are allergic to horse chestnut, avoid it.
Possible cautions and when to ask a pharmacist or doctor
Common effects are local redness, warmth, stinging, itching or mild irritation at the application site.
Stop and seek advice if you develop:
- Increasing redness, swelling, blistering or a spreading rash at the site — possible allergic contact dermatitis, which is easily mistaken for the original problem worsening.
- Wheezing, chest tightness or difficulty breathing — particularly relevant if you are aspirin-sensitive.
- Swelling of the face, lips or tongue.
- A widespread rash.
Seek medical attention rather than continuing self-treatment if:
- Swelling is severe, or increasing rapidly.
- You cannot bear weight on an injured limb, or cannot use it normally.
- There is obvious deformity, or you suspect a fracture.
- Pain is severe, or worsening rather than settling.
- The area is hot, red and tender with fever — possible infection.
- A leg is swollen, warm and painful, particularly one-sided, with or without breathlessness — possible deep vein thrombosis, which needs urgent assessment. A gel is not the treatment for this, and delay matters.
- Numbness, tingling or weakness develops.
- Symptoms have not improved within a week or two.
- Bruising appears without injury, or you bruise unusually easily — this warrants investigation.
If it was swallowed, particularly by a child, contact a doctor or poison centre with the container.

Frequently asked questions
What is Reparil gel used for? Bruises, sprains, strains, soft-tissue swelling, superficial vein inflammation and varicose vein discomfort. It contains diethylamine salicylate with aescin.
What is aescin? The active component of horse chestnut seed extract. It reduces leakage from small blood vessels, which is what makes the gel useful for swelling and bruising.
Is it the same as a diclofenac gel? No. A diclofenac gel is a topical anti-inflammatory aimed at joint and muscle pain. Reparil targets swelling and bruising specifically.
Can I use it on broken skin? No. Apply it only to intact skin — salicylates are absorbed far more readily through damaged skin.
Can children use it? Ask a pharmacist first. Salicylate-containing products are generally avoided in children because of the association with Reye’s syndrome.
Can I use it if I am allergic to aspirin? Check with a pharmacist. Diethylamine salicylate is related to aspirin, and absorbed salicylate can trigger the same reaction.
How long should I use it? For a short period while an injury settles. If symptoms have not improved within a week or two, see a doctor.
When should I see a doctor instead? If swelling is severe, you cannot bear weight, there is deformity, or a leg is swollen, warm and painful — the last may indicate a blood clot needing urgent assessment.
