# Medicated & Antifungal Horse Shampoo: What They Actually Do (and When to Call the Vet)

> What medicated and antifungal shampoos actually treat, when to call a vet, and where a gentle wash like Revive fits in. Ferro is grooming, not medicine.

A medicated or antifungal shampoo exists to help treat a diagnosed skin condition — rain rot, ringworm, scratches, or a bacterial or fungal infection — usually as part of a vet's treatment plan. A grooming shampoo is not a medicated product, and it won't cure a skin disease. Here's the honest difference, and where a gentle everyday wash like [Revive](/product/revive-shampoo/) does and doesn't belong.

## What 'medicated' and 'antifungal' really mean

These shampoos contain active ingredients — things like chlorhexidine, miconazole or benzoyl peroxide — aimed at bacteria, fungi or a specific skin problem. They're treatment products, and the right one depends on what's actually wrong with the skin, which is exactly why a vet's diagnosis matters. Use the wrong active, or reach for an antifungal on a bacterial problem, and you've wasted time while the condition spreads.

### When your horse needs one — and a vet

- Rain rot / rain scald — crusty, scabby patches across the back and quarters. Our guide on [rain rot](/conditions/rain-rot-on-horses/) covers it in full.
- Mud fever / scratches — sore, scabby skin around the heels and lower leg. See [mud fever & rain scald grooming](/conditions/mud-fever-and-rain-scald-grooming/).
- Ringworm — circular hair loss and flaky patches; it's fungal, and it spreads to other horses and people alike.
- Persistent itching, crusting or hair loss that won't clear up — always worth a vet's look before you treat it yourself.

Where Ferro Fits — and Where It Doesn't

Ferro makes grooming products, not medicated shampoos. None of our washes treat an infection, and we won't pretend otherwise. If your horse has a skin disease, get a diagnosis and a vet-recommended medicated product. What a gentle, non-stripping wash like [Revive](/product/revive-shampoo/) *is* good for is everyday hygiene and prevention, keeping skin clean with its natural barrier intact, plus gentle washing of healthy skin between or after a treated episode, once your vet gives the go-ahead.

### Prevention beats treatment

- Keep skin clean and let it dry fully. Most rots and fungal problems thrive on damp, dirty coats.
- Don't share brushes, girths or rugs between horses if one has a skin problem — ringworm and bacteria hitch a ride on shared kit.
- Wash gently and rinse well. Over-stripping the coat weakens the skin barrier that keeps infection out.
- Treat small issues early, and call the vet if they spread. That's cheaper and kinder than letting it become a full outbreak.
