Purim (Proxymetacaine + related components) — Patient Information

Purim is a medicine used in specific situations to help relieve discomfort in the eye and/or related applications depending on the formulation supplied in the United Kingdom. This page provides clear, patient-friendly guidance about what Purim is, how it works, how it’s typically used, and important safety information.

Important: Always follow the instructions given by your pharmacist, optician, or clinician, and read the patient information leaflet supplied with your product. If you’re unsure which exact Purim formulation you have (for example, whether it is an eye preparation or another type), check the label and leaflet before use.

Quick Overview

Basic Product Information

Purim is marketed in the UK in formulations intended for local action. Depending on the specific product, it may be supplied as an eye drop and/or other local application. The exact active ingredients and strengths can vary by manufacturer and packaging, so it’s essential to check:

• the name and strength on the outer carton or label
• the leaflet for your specific product
• any listed active ingredients

If you are buying online, ensure the description on the page matches the product you receive. If you have a history of allergic reactions to local anaesthetics or preservatives, check the ingredient list carefully.

How Purim Works (Mechanism of Action)

The active ingredients in Purim are designed to produce a local anaesthetic effect. In practical terms, this can reduce or numb the sensation of discomfort by blocking nerve signalling in the applied area.

Because the effect is local, Purim is intended for targeted use rather than general pain relief. The medicine typically helps with symptoms such as burning, stinging, or pain associated with superficial discomfort—again, this depends on the product’s intended use.

Pharmacokinetics (What Happens in the Body)

For medicines applied locally, absorption into the bloodstream may be limited, and the main effect occurs at the site of application. With eye preparations, only a small amount may enter systemic circulation, particularly when used correctly.

• Absorption: Local absorption can occur, but systemic exposure is usually low when used as directed.
• Distribution: Any absorbed fraction is distributed through the bloodstream in the usual way for small molecules.
• Metabolism: Metabolism typically occurs primarily in the liver.
• Elimination: The drug and its metabolites are eliminated by normal body clearance pathways, often the kidneys.

Individual factors (age, eye condition, frequency of use, and whether the ocular surface is inflamed or damaged) may affect absorption. Overuse increases the risk of more widespread effects.

Typical Use and Indications

Purim is commonly used for short-term relief of discomfort where a local anaesthetic effect is desired. Indications can include:

• temporary relief of eye discomfort associated with superficial irritation
• use to numb discomfort prior to certain brief procedures or examinations, where appropriate
• helping to reduce pain perception during short-term handling of the eye (as directed by healthcare professionals)

It is not intended as a long-term treatment for underlying causes such as infection, corneal ulcer, allergy, or dry eye disease. If symptoms persist or worsen, seek timely medical advice.

When to Take / How to Time Your Use

Timing depends on why you are using Purim. In many local anaesthetic-type preparations, the effect is achieved quickly after application. You should use it only for the timeframe intended by the product guidance and your clinician/pharmacist.

Common timing examples

• Before an activity: Apply shortly before the intended moment of discomfort relief if advised.
• Short-term use: Use for brief episodes only, not continuously.
• Follow the label: The label instructions are the safest guide for frequency and timing.

If your product is an eye drop, try to apply it at a time when you can safely see clearly after dosing and avoid touching your eyes.

Dosing (Adults and Children)

The correct dose depends on the formulation and strength. Always follow your product leaflet and the instructions provided by a healthcare professional. The information below is general guidance and may not match your exact product.

General dosing principles

• Use the smallest effective amount: More is not better.
• Do not use more frequently than advised: Overuse can increase risks to the eye surface.
• Check age-specific guidance: Some local anaesthetic drops are not recommended for children or have special limits.

If you’re using an eye preparation

Typical instructions for eye drops may include applying one drop to the affected eye(s). Repeat dosing only if the leaflet clearly states it is required and safe for your situation.

If you miss a dose, do not apply extra doses to “catch up.” Use the next dose at the scheduled time only if your leaflet instructs it.

Seek urgent advice if symptoms such as significant eye pain, reduced vision, light sensitivity, or discharge occur.

Food Interactions

Because Purim is typically used locally (e.g., in the eye), food interactions are usually not a concern. No specific food restrictions are typically required.

However, always consider general medical advice:

• If you are taking other medicines, follow their food-related instructions as written.
• If Purim is part of a larger treatment plan, ask your pharmacist whether any systemic medicine interactions apply.

Alcohol and Medicine Interactions

With local preparations, major alcohol interactions are less likely than with systemic medicines. Still, alcohol may worsen irritation, delay recovery, or affect judgement about symptoms.

Alcohol

• General recommendation: Avoid alcohol if it makes your symptoms worse or if you’re feeling unwell.
• Safety: Avoid risky activities if your vision becomes temporarily altered after application.

Other medicines

Potential interactions depend on the exact active ingredients and preservatives used. Please review the leaflet for interaction information, and let your pharmacist know about:

• other eye drops (including artificial tears, steroid drops, antibiotics, and antihistamine drops)
• contact lens products
• medicines for allergies, infections, or eye inflammation
• any history of eye surgery or chronic eye disease

If you use multiple eye products, separate applications as advised (often by several minutes) to reduce wash-out and contamination. Your pharmacist can confirm spacing for your specific products.

Safety Profile and Important Precautions

Purim is generally intended for short-term, local use. Like all medicines, it can cause side effects. Most people tolerate it well when used correctly, but you should be aware of potential risks.

Common possible side effects

• temporary stinging or burning on application
• temporary blurred vision or altered comfort sensation
• redness or irritation

Serious side effects — get urgent medical help

Contact urgent care or seek medical attention promptly if you notice:

• severe or worsening eye pain
• reduced vision or significant light sensitivity
• worsening redness or swelling
• white/yellow discharge or signs of infection
• persistent symptoms that do not improve after short-term use
• symptoms suggesting an allergic reaction (e.g., rash, facial swelling, breathing difficulty)

Eye-safety considerations

• Avoid overuse: Repeated dosing can increase the risk of damaging the eye surface.
• Protect the eye: Because sensation may be reduced, you may not feel injury. Do not rub the eye.
• Contact lenses: Remove contact lenses unless the leaflet specifically permits continued wear. Reinsert only when advised.
• Do not share: Do not use someone else’s medicine.
• Avoid contamination: Do not touch the dropper tip to the eye, eyelids, fingers, or any surface.

Who should take extra care?

• people with corneal problems or previous eye surface injury
• people with glaucoma (unless advised otherwise)
• people who have had allergic reactions to similar medicines
• children—check product suitability and age limits carefully
• pregnant or breastfeeding—discuss with a healthcare professional if uncertain

Practical Use Tips (Step-by-Step)

Correct technique helps reduce contamination and improves effectiveness. The following steps apply to typical eye drop use; follow your leaflet if instructions differ.

1. Wash your hands thoroughly with soap and water.
2. Check the product (name, strength, expiry date, and appearance).
3. Prepare the area with a clean tissue or towel.
4. Tilt your head back and gently pull down the lower eyelid.
5. Apply the prescribed amount into the lower eyelid “pocket.” Avoid touching the eye.
6. Close your eye gently for 1–2 minutes.
7. Press the inner corner (tear duct area) gently for about 30–60 seconds if you can—this can reduce drainage into the nose and help limit systemic absorption.
8. Replace the cap promptly and wash your hands again.

If you use other eye drops, wait between products as advised—often at least 5–10 minutes unless otherwise instructed.

Do not drive if your vision is temporarily blurred after use.

Alternatives to Purim

Depending on the cause of discomfort, your pharmacist or clinician may suggest alternatives. Which option is best depends on whether your symptoms are due to irritation, infection, allergy, dry eye, or another condition.

Possible alternatives (general categories)

• Lubricating drops (artificial tears): Helpful for dry eye and mild irritation.
• Lubricating gels/ointments: Longer-lasting comfort for nighttime use.
• Antihistamine eye drops: For allergic symptoms (itching is often prominent).
• Anti-inflammatory treatment (as advised): For inflammatory eye conditions under appropriate guidance.
• Antibiotic or antiviral treatment: Only when infection is suspected/confirmed by healthcare professionals.

If you’re considering switching, ask your pharmacist: the choice should be guided by symptoms, duration, and whether there are red flags such as discharge, reduced vision, or significant pain.

Market and Legal Context for the United Kingdom

In the UK, medicines are classified according to how they are supplied and controlled. Availability, labelling requirements, and online sale rules depend on whether a product is:

• available over the counter (pharmacy/retail supply), or
• restricted and supplied under pharmacy guidance or by other regulated routes.

Purim products sold online in the UK should comply with relevant UK medicines regulations, including appropriate product information, safeguarding against counterfeit medicines, correct storage conditions, and clear patient instructions. The online pharmacy should also provide transparent information about delivery, returns, and handling.

For the most accurate regulatory status of your specific Purim formulation, check the product label and the “how to get it” information provided by the online pharmacy.

Recent Guidance and Practical Updates (UK-Focused)

Eye-related discomfort often leads to urgent clinical assessment when symptoms persist or are severe. In the UK, healthcare emphasis continues to focus on:

• not masking symptoms when they may indicate serious eye problems
• prompt medical review for red flags such as reduced vision, severe pain, or light sensitivity
• appropriate use of local anaesthetic-type products for short durations only
• infection control and safe handling to avoid contamination

If your eye discomfort does not improve within the timeframe advised by your pharmacist or leaflet, discontinue use and seek advice.

Delivery and Availability (UK)

Purim availability online depends on stock levels and the specific formulation/size you select. In the UK, many pharmacies offer delivery services that can include standard delivery and sometimes faster options.

What to expect

• Processing time: orders may be processed same day or next business day depending on cut-off times
• Delivery windows: vary by courier and service level
• Packaging: medicines are typically dispatched with protective packaging to prevent damage
• Storage: store as directed on the label (commonly at room temperature unless stated otherwise)

If you need it urgently, consider checking delivery options at checkout and allowing extra time for rural postcodes or public holidays.

For hygiene reasons, follow any “after opening” instructions and do not use medicine past its expiry date.

When to Seek Medical Help

Please seek clinical advice urgently if you have any of the following:

• severe eye pain that does not settle
• reduced or worsening vision
• strong light sensitivity (photophobia)
• visible injury (e.g., scratch), chemical exposure, or suspected foreign body
• significant discharge or swelling around the eye
• symptoms persisting beyond the short period expected for the intended use

Local anaesthetic effects may reduce awareness of damage. If you injure the eye or suspect infection, don’t rely solely on symptom relief—get assessed.
