Update November 2024: How to deal with Creon, Nutrizym or Pancrex supply issues

Whilst PERT supply issues continue, please do not stockpile them. Stockpiling will further drive the shortage. 

The Department of Health and Social Care has recommended that only a 1-month supply is issued at a time. This is to try and regulate supplies. So, if you now get 2-3 months of your PERT at a time, you will need to refill your prescriptions more often.  

If you pay for your prescription, you should consider applying for a pre-payment certificate. This will help to reduce the cost of prescription charges. You can find more at https://www.nhsbsa.nhs.uk/help-nhs-prescription-costs/nhs-prescription-prepayment-certificate-ppc. 

• Please request your prescription as soon as the pharmacy has dispensed (given you) your earlier one. This should give the community pharmacist time to source your medication.  
• It is important that you check with your GP surgery that the prescription request has been authorised. Some GP surgeries have an automated system. It rejects repeat prescriptions if they are placed too early. 
• If you still receive a paper prescription. Ask for your PERT prescription on a single script. This will let you take it to another pharmacy if needed, without disrupting your other medications. 
• You may need a change in your repeat prescriptions if what you usually have is not available. There are three brands of PERT usually currently in the UK.  
• Pharmacies should also be able to order in medicines from abroad. 

The following advice will make your PERT as effective as possible:  

• Remember to store your PERT appropriately. All PERT should be stored below 25 degrees, and some brands recommend refrigeration. If PERT gets too hot it does not work properly, this damage cannot be reversed.  
• Taking the PERT throughout the meal rather than all at the start/middle/end improves how well it digests the food and drinks you are eating/drinking.  
• Ensure that you use your PERT before it goes out of date. If you store PERT in different places (i.e. at work), make sure you rotate your supplies to prevent any wastage. 

Stage 1 summary:

Please make sure you: 

• Use your PERT as effectively as possible. Store it correctly and make sure it does not go out of date. 
• Put your next prescriptions in as soon as your earlier one has been dispensed. 
• Check each prescription. Make sure it was approved by your GP surgery. 
• Do not stockpile PERT – this makes the whole situation worse. 
• Be prepared to receive a different brand of PERT to the one you are normally prescribed. 

If your pharmacist can’t get PERT for you and you are waiting for a delivery, take these steps. They will help your existing supply last as long as possible. Manufacturers have customer support lines that may help you find a pharmacist nearby with stock. For Creon, call 0800 808 6410 and for Nutrizym, call 0800 090 2408 (Monday to Friday, 9am to 5pm).

If you have cystic fibrosis, please contact your specialist centre.  

If you are having chemotherapy, preparing for surgery, recovering from surgery, having difficulty eating or struggling with malnutrition, it is important that you do not restrict your PERT dose as this may have an impact on the rest of your treatment. Please contact your managing hospital and request a rescue prescription. 

If you are not already taking one talk to your doctor about taking a proton pump inhibitor. Examples include: 

• omeprazole® 
• pantoprazole® 
• lansoprazole® 

Or a (H2)-receptor antagonist. Examples include: 

• famotidine®  
• nizatidine® 

These reduce the acid in your stomach and make the enzymes more efficient. This means a lower PERT dose than your usual dose may be effective if you have a proton pump inhibitor as well. If this does not appear to be effective, they may be stopped. This may not be appropriate for everyone. 

If you don’t take vitamins and minerals, we recommend that you take a calcium and vitamin D supplement. It should contain 800iu Vitamin D and at least 500mg Calcium. Also, take a multi-vitamin and mineral during this time.  

For example: 

• Sanatogen A-Z Complete®.  
• Centrum Advance®.  
• Or, a supermarket’s own A-Z brand. Please ensure they have both vitamins and minerals. 

People with CF should stay on their vitamins and minerals. They should discuss any concerns with their CF specialist dietitian.

How to reduce your dose to make your supplies last longer 

Firstly: 

• Reduce the dose of PERT by one capsule with any snacks that you take. 
• Make the most of the meals you have and spread your PERT out throughout them to optimise digestion.

If this is not enough: 

• Reduce the dose of PERT by one capsule with each meal and snack, rather than skip whole meal doses. 

If this is not enough: 

• Reduce the dose of PERT by one capsule with each meal and only have a small piece of fruit as a snack in order that you do not need to take any PERT with snacks. 

Please contact your dietitian/nurse specialist or doctor if you are struggling with malabsorption symptoms or are consistently losing weight. 

If you are taking other medication, be aware this may not be as effective as normal, speak to your doctor if this is the case. If you are on the oral contraceptive pill, you should use a second form of contraception. 

Example meal plans

Tips if you are needing to take more capsules of a lower dose as your usual capsules are not available, and are struggling with the number of capsules you need to take.  

• If you have some high dose PERT left, take this with you when you go out, and use the low dose capsules when you are at home.
• If swallowing the capsules is putting you off your meals take some of them at the end of the meal. For instance, if you need to take 20 capsules with your meals, take 5 at the start, 5 in the middle and 10 at the end.  
• Ensure you do not chew or crush the tablets, this will make them less effective and can damage your gums or cause unpleasant mouth ulcers.  

 Advice for people with diabetes  

If your diabetes is controlled by diet or you take Metformin/DPP-4 inhibitors (Gliptins)/ SGLT 2 inhibitors (Gliflozins) without any other medication, you do not need to change any of your diabetes management.  

If you take insulin or medicines that can cause a hypo/low blood sugar (i.e. Gliclazide) please read the advice below carefully:  

If you take less enzymes with your food, you are likely to absorb less starchy carbohydrate from food. Simple sugar absorption Is not affected by a lack of PERT. This will mean that usual carbohydrate counting techniques may be less reliable. Therefore, you may need to reduce the amount of quick acting or mixed insulin you inject to prevent a hypo*.  

*A hypo is when your blood glucose level goes below 4mmol/l. 

Typical symptoms include  

• Sweating  
• Shaking  
• Blurred vision  
• Confusion  
• Palpitations  

Always keep hypo treatment on you. You can find more information on recognising and treating a hypo from your diabetes team or by clicking here. 

You are only at risk of a hypo if you take medication that increase the amount of insulin in your blood. It is not usually possible to have a hypo if you have diet-controlled diabetes, or diabetes treated with metformin/DPP-4 inhibitors (Gliptins)/SGLT 2 inhibitors (Gliflozins) alone.  

Monitor your blood glucose levels regularly: before meals, before bed, if you are feeling unwell, if you feel like you are having a hypo* and before driving. If you are driving long distances, make sure you check your blood glucose levels at least every two hours. 

If you have a continuous glucose monitor, ensure you have the low alert alarm set. This will alert you if your blood sugars become low. If you are having more hypos than usual, you may need to contact your CF/NEN/diabetes team for advice on adjusting your insulin doses.  

If you have had a hypo, please make sure you have enough PERT to take with the starchy carbohydrate snack you take to maintain your blood sugars (digestive biscuit / sandwich / scone / crumpet etc.). Speak to your diabetes team for advice on reducing your insulin or medication if you start having hypo’s or need to reduce your PERT dose.  

Advice for people taking nutritional supplement drinks 

If you take oral nutritional supplements (i.e., Altraplen® Amyes®, Ensure®, Foodlink® Fortisip®, Fresubin®), ask your dietitian if they can be changed to a peptide / semi-elemental preparation (i.e., Vital 1.5kcal®, Survimed OPD 1.5kcal®, Peptisip Energy HP®) as most people can manage these without additional enzymes.  

These do not come in a wide range of flavours, but you can add milkshake mixes or coffee syrups to increase the range of flavours. Serve them chilled or freeze them into ice lolly moulds or ice cube trays to give you more options.  

Sometimes you may be asked to try individual protein supplements or a fat-free nutritional supplements (Actagain Juce®, Altrajuce®, Ensure Plus Juice®, Fortijuce®, Fresubin Jucy® etc.,). You should sip these slowly to give your gut more time to digest them without PERT. If you have diabetes monitor your blood glucose levels closely when taking these.  

If you feel bloated with these, don’t worry – this is a normal effect of taking these without PERT, but if it is affecting your quality of life, please let your dietitian know. 

Advice for people taking other medication 

Please be aware that other medication you take may be less effective if you are not absorbing. This is particularly important for people who take medications to prevent seizures, the formation of blood clots and the oral contraceptive pill. If you are on the oral contraceptive pill, a secondary form of contraception should be used at this time. Please talk to your doctor or specialist team. 

Do not worry, this should not last long.  

Ask your GP what plans are in place in your local area to support people who have run out of PERT. You may be able to talk to a pharmacist at your GP surgery about this.  

If you have had a total pancreatectomy or are taking insulin, please make an emergency (same day) appointment with your GP. You can show them this document.  

If you are under the care of a local hospital, please contact your local hospital team and ask for a rescue prescription. 

Symptom management without PERT

If you reduce your dose and start experiencing symptoms such as diarrhoea, severe bloating, or urgency to need to have your bowels open, here are some other steps to try to reduce the symptoms:  

• If you are struggling with diarrhoea, consider taking some loperamide/Imodium® before your main meal. This should help to slow down your gut and reduce diarrhoea. The longer food is within your gut, the more chance more of it will be absorbed by your body.  

Please note, if this is a new sudden onset of diarrhoea, infection should be ruled out before loperamide is used.  

The above medicine (Loperamide) is not suitable for people with CF. Please contact your specialist CF Team)  

• Reduce the amount of fat in your meal to ½ of your normal the portion size of higher fat foods (Table 1). This is likely to improve some of your gut symptoms but will not mean you absorb more nutrition or prevent malnutrition, so keep a close eye on your weight and strength.  
• If you eat a lot of high fibre foods – consider reducing these as very high fibre foods can bind to enzymes and make them less effective. (Table 2) Healthy eating guidelines recommend adults try to eat 30g of fibre per day. We recommend not exceeding 40g at this time.  
• If you do not have diabetes, use sugary foods and drinks to increase your energy intake. Table sugar does not require enzymes to be absorbed in your gut, so Lucozade, adding sugar/honey/syrup to foods and nibbling on sugary sweets/marshmallows (not chocolate) can help keep your energy levels up. But these do not provide any other nutrition so make sure you are having protein, vitamins and minerals from other sources.  
• If you are losing weight, please speak to your dietitian or GP about taking some peptide based nutritional supplement drinks. These are a specialist type of supplement drink that require a lot less enzymes for absorption, so can usually be taken without PERT. These are called Vital 1.5kcal®, Survimed OPD 1.5kcal®, Peptisip Energy HP®. They are more expensive than other supplement drinks, but really useful if you cannot take PERT.  
• If you have enough PERT to take some with your main meal, eat this as usual and use half the dose of supplement drinks in place of your other meals. 

 Advice for people taking other medication  

Please be aware that other medication you take may be less effective if you are not absorbing. This is particularly important for people who take medications to prevent seizures, the formation of blood clots and the oral contraceptive pill. If you are on the oral contraceptive pill, a secondary form of contraception should be used at this time.  

Please talk to your doctor or specialist team if you are taking medicines for other conditions. If you take medication to stop your blood from clotting (anti-coagulation) please inform your doctor that you have run out of PERT. Vitamin K which helps control blood clotting is a fat soluble vitamin and the absorption of this will be reduced whilst you are not on PERT. You may need more regular monitoring. 

Advice for people with diabetes 

You need a supply of PERT If you take insulin or medications that increase the amount of insulin in your blood (i.e. Gliclazide). You may be asked to travel to a hospital to collect this. In the meantime, you should monitor your blood sugars more regularly. If you have a continuous glucose monitoring device, ensure you have the low blood sugar alert set up.  

Check your blood sugars more regularly when driving and ensure you carry “hypo” treatments with you. Sugary foods such as dextrose tablets, glucogel®, and jelly sweets will still be absorbed, but your “long acting” carbohydrates (sandwiches/digestive biscuits etc.,) may not be as effective at maintaining your blood sugars when taken without PERT. 

Table 1: High fat foods and their lower fat alternatives 

	Reduce your portion size of these.	Have these instead:
Fats and oils	Butter, lard, Ghee, Margarine, cooking oils	Small portions of low-fat spreads   Use spray on cooking oils if needed
Dairy products	Full fat milk / yoghurt   Cream   Crème Fraiche   Cheese	Semi-skimmed or skimmed milk.   Low fat yoghurts   Use small amounts of grated cheese instead of slices of cheese – choose stronger cheeses to maximise taste.   To increase your protein intake, make skimmed milk powder up using skimmed milk and use in place of milk throughout the day
Meat and Fish	Fried foods or foods cooked in batter     Skins / visible fat on meat     Tinned fish, tinned in oil	Meat and fish cooked without added oil     Tinned fish, tinned in spring water / brine
Plant based protein sources	Nut butters	Pulses (e.g. lentils, chickpeas, beans (note portion sizes in table 4)   Quorn / Tofu – up to 100g
Fruit & vegetables	No restrictions for low fat, see Table 4 for fibre suggestions
Carbohydrate based foods	Croissants, pastries     Chips / Fried     Roast potatoes	Bread, Breakfast cereals     Potatoes, rice, pasta, cooked without added fat
Sauces / Condiments	Cheese based sauces   Creamy sauces (bearnaise, hollandaise etc.,)   Large portions of mayonnaise	Tomato based sauces, gravy,   mustard, tomato ketchup, soy sauce,   mint jelly, vinegar or low-fat salad   dressings

 

*Please note: Patients with Carcinoid Syndrome, please do not introduce foods you have previously been advised to avoid.

If you are without supplies for more than 3 to 4 days 

If you are under the care of a hospital team, contact them and see if they have sufficient supplies to issue a prescription for you – you will have to travel to the hospital to collect these if they have some available.  

Inform your pharmacist that you have completely run out, so your supply can be prioritised if possible. Try not to worry, supplies are regularly coming into the country – so running out completely will be a short-term issue. 

Try not to worry, supplies are regularly coming into the country. So, this will be a short-term issue. 

If you are unable to eat food because of your symptoms 

Drink plenty of fluids. Include Lucozade®, sports drinks or Dioralyte®.  

Ask your GP for a peptide nutritional supplement to be prescribed (Vital 1.5kcal®, Survimed OPD® 1.5kcal or Peptisip Energy HP®) – you can show them this leaflet. If you are known to a dietitian – they can be contacted too, but due to the massive increase in workload this PERT shortage is generating, you are likely to get these more quickly if you go directly to your GP.  

These can be used instead of meals until you have your enzymes again. If you do not have diabetes, you can continue to have sugary foods and drinks alongside these. The table below shows how many supplement drinks you should take if you do not have any PERT at all.  

These do not come in a wide range of flavours, but you can add milkshake mixes or coffee syrups to increase the range of flavours. Serve them chilled or freeze them into ice lolly moulds or ice cube trays to give you more variety. 

Recommended doses for peptide based nutritional supplement drinks if you are unable to absorb your food. 

Body weight	Supplements needed per day.   (Vital 1.5kcal® or Survimed OPD 1.5kcal® or Peptisip Energy HP®)
Below 40kg (6st 4lb)	Contact a dietitian
40 – 50kg (6st 4lb- 7st 12lb)	4 x 200ml bottles = 1200kcal
50 – 60kg (7st 12lb – 9st 6lb)	5 x 200ml bottles = 1500kcal
60 – 70kg (9st 6lb – 11st)	6 x 200ml bottles = 1800kcal
70 – 80kg (11st – 12st 8lb)	7 x 200ml bottles = 2100kcal
80 – 90kg (12st 8lb – 14st 2lb)	8 x 200ml bottles = 2400kcal
Over 90kg (14st 2lb)	Contact a dietitian

This may under-estimate your needs, if you lose weight or are very active, add in one more bottle per day. If you gain weight and were not intending too – reduce by 1 bottle per day. 

Suitable foods to eat without PERT  

Whilst you are on these supplement drinks you can snack on the following:  

• Fruit – a handful sized portion at a time.
• Vegetable sticks (carrot, celery, cucumber).
• Small amounts of salsa/ketchup/balsamic vinegar/marmite/mustard – tiny amounts can be used to give vegetable sticks a slightly different taste.  

If you do not have diabetes, you can also try:  

• Sorbet  
• Marshmallows  
• Sugary sweets (not chocolate, fudge or toffee)  

Please note this is generic advice. Do not introduce foods you have previously been advised to avoid. 

These foods will not give you many calories, but they should not make your symptoms worse and will fill you up a bit more than having the supplement drinks on their own. 

You can eat other foods, but these may worsen any abdominal symptoms you are experiencing. 

A suggested daily meal plan for someone who weighs 80kg may look like this:  

• Breakfast: 1 x supplement drink, cup of black coffee and a banana  
• Mid morning: I x supplement drink, carrot sticks  
• Lunch: 2 x supplement drinks flavoured with chocolate coffee syrup and served with ice, cucumber and celery sticks dipped in salsa  
• Mid-afternoon: 1x supplement drink and an apple  
• Dinner: 1 x supplement drink and some carrot sticks with a smear of marmite; 1 x frozen supplement drink served with a handful of strawberries, raspberries and a scoop of sorbet. 

For patients who already have a gastric feeding tube  

If you have a PEG, RIG or NG feeding tube, you could take your PERT from a powdered source (Pancrex® V powder) through this tube. These can be dissolved in water and flushed down the tube, but this must be done at the time you eat. This does not work with a jejunostomy or naso-jejunal tube as the enzymes will not mix with your food. If you have a feeding tube, discuss this option with your dietitian.  

For all patients with feeding tubes  

If you normally receive some of your nutrition through a feeding tube, or have one that you are not currently using, it may be beneficial to increase your feed through the tube whilst you do not have any PERT. Please speak to your dietitian about this.
