Nettle and plant stings
Common nettle stings are painful and itchy but harmless — the raised red patches usually settle within an hour or two. A few plants can cause more serious skin reactions, particularly giant hogweed, which can cause blistering and long-lasting sensitivity to sunlight.
Looking after yourself
- Rinse the area with cool water
- Try not to scratch
- Antihistamine tablets or a hydrocortisone cream from a pharmacy can help itching
- Suspected giant hogweed: wash the area thoroughly with soap and water and keep it out of sunlight for at least 48 hours
When to get medical help
Use NHS 111 online, call 111, or contact your GP if:
- A rash that blisters or lasts more than a day
- Widespread rash after touching a plant
- Signs of an allergic reaction
Call 999 or go to A&E if you have swelling of the tongue or throat, difficulty breathing, or feel faint — these are signs of a severe allergic reaction.
