What Is After Bite Sting Relief Used For?
Insect bites and stings are a common and often painful part of spending time outdoors, particularly during the warmer months. The immediate sensation of a sting followed by persistent itching, redness, and localised swelling is familiar to almost everyone, and having an effective, fast-acting remedy to hand can make a real difference. After Bite Sting Relief is a topical preparation formulated to help relieve the itching and discomfort associated with insect bites and stings, delivering its active ingredient quickly and precisely to the affected site via a convenient pen applicator for fast, targeted relief wherever you are.
The active ingredient is ammonia solution, an alkaline compound with a well-established history of use in topical bite and sting relief. The majority of insect bites and stings work by depositing acidic or protein-based venoms and irritants into the skin, and it is these substances that activate the nerve endings responsible for the sensation of itching and pain. Ammonia, being alkaline, helps to neutralise these acidic irritants when applied directly to the skin, reducing the chemical signal driving the discomfort. This mechanism of action is rapid and localised, providing meaningful relief at the bite site within moments of application without the need for oral medicines or complex preparations.
The pen applicator format delivers a controlled, precise amount of the ammonia solution onto the skin through a felt tip, making application clean, targeted, and mess-free. The compact size of the pen means it is easy to keep in a pocket, handbag, or first aid kit for immediate use when a bite or sting occurs. This is particularly useful when outdoors, in the garden, on camping trips, or during travel to regions with higher insect activity.
After Bite Sting Relief is suitable for adults and children aged 2 and over. It should not be applied to broken or infected skin and care must always be taken to avoid the eye area. For bee stings specifically, always ensure the sting has been removed from the skin before applying any relief product. If a bite or sting produces signs beyond localised discomfort — such as significant swelling, difficulty breathing, widespread rash, or dizziness — seek emergency medical help immediately. A Pearl Chemist Group pharmacist is always available to advise on bite and sting management, and you can also browse our full bite and sting relief range for further options.
How to Use After Bite Sting Relief
- For bee stings, remove the sting first. Gently scrape the sting out using a flat-edged object. Do not squeeze with tweezers. Wasp stings do not leave a sting in the skin.
- Remove the cap. Twist or pull off the pen cap to expose the felt tip applicator.
- Apply to the bite or sting site. Press the felt tip firmly onto the centre of the affected area to release the ammonia solution. Hold for a moment to allow transfer to the skin.
- Allow to dry. Let the solution dry naturally. Do not immediately wipe the area.
- Reapply if needed. If discomfort persists after a few minutes, reapply to the same site.
- Replace the cap immediately. Always replace the cap firmly after use to prevent evaporation of the ammonia and maintain product effectiveness.
Tips for best results
- Apply as soon as possible after the bite or sting occurs for fastest relief.
- Store the pen in a cool, shaded place when outdoors to minimise evaporation through the cap.
- Do not hold the applicator tip near the face or inhale the vapour deliberately.

After Bite Sting Relief is generally well tolerated on intact skin. Adverse reactions are uncommon.
Common side effects (may affect more than 1 in 10 people)

- Mild ammonia odour during and after application
Less common side effects (may affect between 1 in 10 and 1 in 100 people)

FAQs
After Bite Sting Relief contains ammonia solution, which is an alkaline compound. When insects bite or sting, they deposit acidic venom and irritants into the skin that activate itching and pain receptors. Applying ammonia to the site neutralises these acidic substances, reducing the chemical stimulus that is driving the discomfort. The effect is rapid and localised, typically providing noticeable relief within moments of application.
Yes. Always remove a bee sting from the skin before applying any topical treatment. Scrape the sting out gently with a flat-edged object rather than squeezing it with tweezers. Squeezing can push more venom from the attached venom sac into the skin. Once removed, apply After Bite Sting Relief directly to the sting site for fast soothing relief.
After Bite Sting Relief and After Bite Classic share the same active ingredient — ammonia solution 3.5% w/w — and work in the same way to provide fast relief from insect bite and sting discomfort. Both are presented in a pen applicator format. If you are unsure which After Bite product is most suitable for your needs, speak to a Pearl Chemist Group pharmacist who can help you choose.
After Bite Sting Relief is suitable for children aged 2 and over under adult supervision. For younger children or those with particularly sensitive skin, After Bite for Kids may be a more appropriate choice, as it uses a gentler ammonia-free formula with soothing botanical ingredients specifically designed for children's skin.
Ammonia is a volatile compound that evaporates when exposed to air. If the cap is not replaced firmly after each use, the active ingredient will gradually evaporate from the applicator, reducing the concentration of ammonia over time and making the pen less effective. Keeping the cap on between uses is essential to maintaining the product's potency.
Call 999 immediately if a bite or sting causes any of the following: significant swelling beyond the immediate bite site, difficulty breathing, swelling of the face or throat, widespread hives or rash, dizziness, feeling faint, or a rapid heartbeat. These are warning signs of anaphylaxis, a life-threatening allergic reaction that requires emergency treatment, not topical first aid. After Bite Sting Relief is only appropriate for mild, localised discomfort from bites and stings in people without a history of severe allergic reactions.
