What Is After Bite Soothing Bite & Sting Relief Classic Used For?
Whether you are spending time in the garden, on a camping trip, at a barbecue, or simply going about daily life outdoors, insect bites and stings are an inevitable part of warmer months in the UK. The immediate itching, stinging, and localised discomfort they cause can be surprisingly intense and persistently distracting. After Bite Soothing Bite & Sting Relief Classic is a fast-acting topical preparation designed to help relieve the itching and discomfort caused by insect bites and stings, providing targeted, on-the-spot relief when you need it most. Its compact pen applicator format makes it one of the most convenient and portable bite relief products available, slipping easily into a pocket, handbag, or first aid kit.
The active ingredient is ammonia solution at a concentration of 3.5% w/w. Ammonia is an alkaline compound, and its mechanism of action in relieving insect bite discomfort relies on a simple but effective chemical principle. Most insect bites and stings involve the injection of acidic or protein-based venoms and irritants into the skin, and it is these substances that trigger the localised inflammation, itching, and pain. When ammonia is applied topically to the affected area, its alkalinity helps to neutralise these acidic irritants in the superficial layers of the skin, rapidly reducing the chemical stimulus that is driving the itch and sting sensation. The result is a noticeable, rapid soothing effect that helps to interrupt the itch-scratch cycle and prevent further skin irritation from repeated scratching.
The pen applicator format of After Bite Classic is designed for precise, clean, and mess-free application directly to the bite or sting site. The felt tip releases a controlled amount of the ammonia solution onto the skin with each application, avoiding the waste and mess associated with creams or lotions applied from a tube. The 14ml pen provides multiple applications and fits easily in any pocket, bag, or first aid kit, making it practical for use at home, in the garden, on walks, or when travelling abroad.
After Bite Classic is suitable for adults and children aged 2 and over. It is not intended for use on broken, damaged, or infected skin, and care must be taken to avoid contact with the eyes. Before applying to a bee sting, always ensure the sting itself has been removed from the skin first. If a bite or sting causes significant swelling, breathing difficulty, dizziness, or widespread rash, seek emergency medical attention immediately as these may be signs of a severe allergic reaction. For everyday bite and sting relief, you can also explore our full range of bite and sting treatments at Pearl Chemist Group.
How to Use After Bite Classic
- For bee stings, remove the sting first. Before applying any treatment, scrape out the bee sting from the skin using a flat-edged object such as a fingernail or credit card edge. Do not use tweezers, as squeezing the venom sac can release more venom. Wasp stings do not leave a sting in the skin.
- Remove the cap from the pen applicator. Twist or pull off the cap to expose the felt tip applicator. Store the cap safely as it protects the tip and prevents the solution from evaporating between uses.
- Apply to the bite or sting site. Press the felt tip of the pen firmly onto the affected area of skin. Hold in place for a moment to allow the ammonia solution to release onto the skin. Apply directly to the centre of the bite or sting.
- Allow to dry. Allow the solution to dry naturally on the skin. Do not rub or wipe the area immediately after application.
- Reapply if needed. If the itching or discomfort has not subsided after a few minutes, reapply the pen to the same area. Most people notice a significant improvement within moments of application.
- Replace the cap immediately after use. Always replace the cap firmly after each application to prevent the ammonia solution from evaporating and to maintain the effectiveness of the pen.
Tips for best results
- Apply as soon as possible after being bitten or stung for the most effective relief.
- The pen is designed for precise application — apply only to the bite site rather than a wide area of skin.
- Keep the pen in a cool, shaded place when carrying it outdoors, as excessive heat may accelerate evaporation.
- Do not hold the pen tip close to the face and avoid inhaling the vapour directly.
After Bite Classic Side Effects
After Bite Classic is generally well tolerated when applied as directed to intact skin. Adverse reactions are uncommon.
Common side effects (may affect more than 1 in 10 people)
- A brief stinging or cooling sensation immediately upon application to the bite site — this is expected and usually transient
- A mild ammonia odour during and immediately after application
Less common side effects (may affect between 1 in 10 and 1 in 100 people)
- Mild, temporary skin redness at the application site
- A brief intensification of the stinging sensation immediately after application before the relief effect develops, particularly on freshly bitten or sensitive skin
Rare side effects (may affect fewer than 1 in 100 people)
- Skin irritation, contact dermatitis, or allergic skin reaction at the application site in individuals sensitive to ammonia
Stop using and seek medical help if you experience:
- Persistent or worsening skin irritation, redness, blistering, or swelling at the application site
- Any signs of a systemic allergic reaction following a bite or sting — call 999 immediately
Report any unexpected reaction via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk or speak to your Pearl Chemist Group pharmacist.

Active Ingredients in After Bite Classic
| Ingredient | Strength | Role |
|---|---|---|
| Ammonia solution | 3.5% w/w | The active ingredient. Ammonia is an alkaline compound that helps to neutralise the acidic irritants and venom components deposited in the skin by insect bites and stings. By raising the local pH at the bite site, it reduces the chemical stimulus responsible for the itching, stinging, and discomfort associated with insect bites and stings. The effect is rapid and localised, providing quick soothing relief without systemic absorption of any significance at this concentration. |
After Bite Classic Dosage — How Much to Apply
Adults and children aged 2 and over
- How to apply: Remove the cap from the pen applicator and press the felt tip firmly onto the affected area of skin to release the solution. Apply directly to the bite or sting site.
- Frequency: Apply as needed when itching or discomfort is present. Repeat the application after a few minutes if the initial application does not provide sufficient relief.
- Duration: Use as required for the duration of bite or sting discomfort. Do not apply to the same area excessively.
Children under 2 years
Not recommended without prior medical advice.
Important application notes
- For bee stings, always remove the sting from the skin before applying After Bite, as leaving the sting in place means venom continues to be released.
- Do not apply to broken, cracked, or infected skin.
- Keep away from the eyes, nose, and mouth.
- Do not inhale the vapour directly from the applicator tip.
Precautions When Using After Bite Classic
Before you use this product
- Check that the skin at the bite or sting site is intact and not broken or infected.
- For bee stings, remove the sting from the skin before applying any treatment.
- Assess whether the reaction to the bite or sting is mild and localised, or whether it appears to be spreading or causing systemic symptoms — in the latter case, seek emergency help rather than applying topical relief.
During use

FAQs
How does After Bite Classic work on insect bites and stings?
After Bite Classic contains ammonia solution at 3.5% w/w, which is an alkaline compound. Most insect bites and stings deposit acidic irritants and venom into the skin. By applying an alkaline solution to the bite site, After Bite helps to neutralise these acidic substances, reducing the chemical stimulus that causes itching and stinging. The effect is rapid and localised, with most people noticing relief within moments of application.
Can I use After Bite Classic on a bee sting?
Yes, but you must first remove the bee sting from the skin before applying any treatment. The bee sting should be scraped out gently using a flat-edged object such as a fingernail or the edge of a credit card. Do not use tweezers or squeeze the sting, as this can push more venom into the skin. Once the sting is removed, apply After Bite Classic to the site as normal. Note that wasp stings do not leave a sting in the skin, so you can apply directly after a wasp sting.
Is After Bite Classic suitable for children?
After Bite Classic is suitable for children aged 2 and over under adult supervision. For younger children or those with particularly sensitive skin, the After Bite for Kids formulation may be more appropriate, as it uses a gentler ammonia-free formula with soothing botanical ingredients. If you are unsure which product is right for your child, speak to a Pearl Chemist Group pharmacist for guidance.
How quickly does After Bite Classic work?
Most people notice a significant reduction in itching and discomfort within moments of applying After Bite Classic to the bite or sting site. The rapid action is due to the immediate alkaline neutralisation of the acidic bite irritants. If full relief is not achieved with the first application, a second application after a few minutes will usually provide additional benefit.
What is the difference between After Bite Classic and After Bite for Kids?
After Bite Classic contains ammonia solution as its active ingredient, which rapidly neutralises acidic bite irritants for fast relief. After Bite for Kids uses a gentler, ammonia-free formula based on sodium bicarbonate (baking soda) combined with soothing botanical extracts including aloe vera and chamomile. The Kids formula is specifically designed for children's more sensitive skin and provides a milder, more gradual soothing effect. Adults with particularly sensitive skin may also prefer the Kids formula.
Can I use After Bite Classic if I am pregnant?
Systemic absorption from the topical application of ammonia solution at 3.5% concentration to a small area of intact skin is expected to be very low. As a general precaution, we recommend consulting your pharmacist before using any topical product during pregnancy, particularly over large areas of skin or repeatedly over a prolonged period.
When should I seek medical help rather than using After Bite Classic?
Seek emergency medical help immediately by calling 999 if a bite or sting causes significant swelling beyond the immediate site, a widespread skin rash or hives, difficulty breathing, dizziness, feeling faint, nausea, or rapid heartbeat. These are signs of a potentially life-threatening allergic reaction (anaphylaxis) and require urgent medical treatment, not topical bite relief. After Bite Classic is only appropriate for mild, localised bite and sting discomfort.
Why must I always replace the cap after using After Bite Classic?
Ammonia is a volatile compound that evaporates readily when exposed to air. If the cap is not replaced firmly after each use, the ammonia will gradually evaporate from the felt tip applicator, reducing the concentration of the active ingredient over time and making the pen less effective. Keeping the cap on when not in use ensures the product maintains its full potency throughout its shelf life.
