The Story
Are Macrogol Sachets for Constipation Right for You?
Constipation is something most people experience at some point, and it can be genuinely uncomfortable — leaving you feeling bloated, sluggish, and frustrated. CosmoCol Orange Lemon and Lime Flavour sachets offer a straightforward, pleasant-tasting way to get things moving again. Each box contains 30 sachets, giving you a generous supply at an accessible price of just £9.29. If you're looking for a reliable option from our constipation range, CosmoCol is well worth considering.
The active ingredient is macrogol 3350, a well-established osmotic laxative that has been used in the UK for many years. It's available over the counter, meaning you don't need a prescription to buy it. The orange, lemon, and lime flavouring makes it noticeably more palatable than unflavoured alternatives — a small but meaningful difference when you're taking it regularly.
How Does CosmoCol Work to Relieve Constipation?
Macrogol 3350 works through a process called osmosis. Rather than stimulating the bowel muscles directly, it draws water into the large intestine, softening the stool and increasing its bulk. This makes it easier and more comfortable to pass. Because macrogol is not absorbed into the bloodstream, it acts entirely within the gut — which is one reason it's generally well tolerated.
- Macrogol 3350 binds water molecules in the bowel
- Stool softens and increases in volume
- Bowel movements become easier to pass
- No systemic absorption — acts locally in the gut
Who Should Consider Using CosmoCol Sachets?
CosmoCol is suitable for adults and young people aged 12 and over who are experiencing constipation. It's particularly useful if you find stimulant laxatives too harsh, or if you need something you can take consistently over a short period. It's also a practical choice for people who struggle with plain-tasting laxative powders, thanks to its citrus flavouring.
- Adults experiencing occasional or persistent constipation
- Young people aged 12 and over (under medical guidance for younger children)
- Those who prefer a flavoured, easy-to-dissolve sachet format
- People who find stimulant laxatives cause cramping or discomfort
How Does CosmoCol Compare to Other Laxative Sachets?

Is CosmoCol Suitable During Pregnancy or for Long-Term Use?
If you are pregnant, breastfeeding, or managing a long-term condition such as irritable bowel syndrome, it's important to speak to your GP or pharmacist before starting any laxative. While macrogol sachets for constipation are generally considered safe for short-term use, ongoing constipation may signal an underlying issue that warrants investigation. You might also find it helpful to explore our IBS and cramps collection if your symptoms are more complex.
Store CosmoCol sachets below 25°C in a dry place, away from direct sunlight and out of reach of children. Do not use sachets past the expiry date printed on the packaging.

Specifications of CosmoCol Orange Lemon and Lime Flavour - 30 Sachets
What Is CosmoCol and What Is It Used For?
CosmoCol Orange Lemon and Lime Flavour sachets contain macrogol 3350 as the active ingredient. Macrogol 3350 is an osmotic laxative used to treat constipation in adults and adolescents aged 12 and over. Constipation is defined as having fewer than three bowel movements per week, or passing stools that are hard, dry, and difficult to pass. The NHS notes that constipation is very common and affects people of all ages.
Each sachet is dissolved in water and taken orally. The citrus flavouring — orange, lemon, and lime — helps make the solution more pleasant to drink compared to unflavoured macrogol products. CosmoCol is available without a prescription and is suitable for short-term use at home.
What Do You Need to Know Before Using CosmoCol?
Before using CosmoCol, read the following carefully. Do not use this product if any of the contraindications below apply to you.
Do not use CosmoCol if you have:
- A known bowel obstruction or suspected perforation
- Paralytic ileus (a condition where the bowel stops working)
- Severe inflammatory bowel conditions such as toxic megacolon
- A known allergy to macrogol 3350 or any other ingredient in the sachet
- Crohn's disease or ulcerative colitis — seek medical advice first
Drug interactions to be aware of:
- Macrogol 3350 may theoretically affect the absorption of other oral medicines if taken at the same time — leave a gap of at least two hours between CosmoCol and other medications
- No clinically significant interactions have been identified at standard doses, but always inform your pharmacist of all medicines you are taking
How Should You Use CosmoCol Sachets?
Using CosmoCol correctly is straightforward. Follow these steps each time you take a dose:
- Tear open one sachet along the perforated edge
- Pour the contents into a glass containing approximately 125 ml of water
- Stir well until the powder is completely dissolved — this usually takes about 30 seconds
- Drink the solution immediately once dissolved
- Repeat for each sachet if taking more than one dose per day
| Indication | Age Group | Dose | Frequency |
|---|---|---|---|
| Constipation | Adults and children 12+ | 1–3 sachets | Once daily or divided doses |
| Faecal impaction | Adults (under medical supervision) | Up to 8 sachets | Divided over the day — seek GP advice |
Do not give CosmoCol to children under 12 without specific medical advice. If you are managing a digestive condition alongside constipation, you may also find our indigestion collection useful for related symptoms.
What Are the Possible Side Effects of CosmoCol?
Like all medicines, CosmoCol can cause side effects, although not everyone experiences them. Most side effects are mild and relate to the gut adjusting to increased water content in the bowel.
Common side effects:
- Abdominal bloating or distension
- Flatulence (wind)
- Mild stomach cramps or discomfort
- Nausea
- Loose stools or diarrhoea if the dose is too high
Less common side effects:
- Vomiting
- Allergic reactions — including rash, urticaria, or in rare cases anaphylaxis
- Electrolyte disturbances (more likely with high doses or prolonged use)
- Peripheral oedema (swelling of the ankles or feet)
If you experience signs of a severe allergic reaction — such as swelling of the face, lips, or throat, or difficulty breathing — stop taking CosmoCol immediately and seek emergency medical help. If you develop persistent diarrhoea, reduce your dose or stop taking the product and speak to a pharmacist. You can also browse our diarrhoea collection if you need support managing loose stools.
How Should You Store CosmoCol Sachets?
- Store below 25°C in a dry place
- Keep away from direct sunlight and moisture
- Keep out of the sight and reach of children
- Do not use after the expiry date printed on the outer carton
- Once dissolved in water, use the solution immediately — do not store prepared solution
- Do not dispose of medicines via wastewater or household waste — return unused sachets to your pharmacy

Frequently Asked Questions
Where can I buy CosmoCol Orange Lemon and Lime sachets online in the UK?
You can buy CosmoCol Orange Lemon and Lime 30 Sachets directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £9.29. No prescription is needed as it is an over-the-counter medicine. Simply add it to your basket and it will be dispatched to your door.
How do macrogol sachets for constipation work in the body?
Macrogol 3350 works by drawing water into the large bowel through osmosis, which softens the stool and makes it bulkier and easier to pass. Unlike stimulant laxatives, it does not cause the bowel muscles to contract forcefully, so it tends to be gentler. Because it is not absorbed into the bloodstream, it acts entirely within the gut.
How do I use CosmoCol sachets step by step?
Dissolve one sachet in approximately 125 ml of water, stir until fully dissolved, and drink the solution straight away. Adults and young people aged 12 and over can take one to three sachets per day depending on how severe their constipation is. Always read the patient information leaflet included in the pack before use.
What is the correct dose of CosmoCol for adults?
The standard adult dose for constipation is one to three sachets per day, which can be taken all at once or spread across the day. Do not exceed three sachets in 24 hours for routine constipation without speaking to a doctor first. For faecal impaction, higher doses may be used but only under medical supervision.
When is the best time to take CosmoCol sachets?
There is no single fixed time that is clinically required, but many people find taking CosmoCol in the morning with breakfast helps establish a regular bowel routine. If you are taking multiple sachets per day, spreading them across morning and evening can help reduce bloating. Consistency matters more than the exact time of day.
What are the side effects of CosmoCol sachets?
The most common side effects are abdominal bloating, wind, and mild stomach cramps, which often settle after the first few days of use. Loose stools or diarrhoea can occur if the dose is too high — simply reduce the number of sachets you take. Rarely, allergic reactions can occur; stop use and seek medical help if you develop a rash, swelling, or breathing difficulties.
How do I manage side effects from CosmoCol?
If you experience bloating or cramps, try reducing your dose by one sachet per day and see if symptoms improve. Drinking plenty of water throughout the day can also help your gut adjust more comfortably. If side effects persist or worsen, speak to your pharmacist or GP.
Who is eligible to use CosmoCol sachets?
CosmoCol is suitable for adults and young people aged 12 and over for the short-term relief of constipation. It should not be used in people with bowel obstruction, perforation, or severe inflammatory bowel disease without a doctor's guidance. Pregnant or breastfeeding women should consult their GP or midwife before use.
Can children under 12 use CosmoCol sachets?
CosmoCol Orange Lemon and Lime sachets are not recommended for children under 12 without specific medical advice. Younger children may require a different formulation or dose that is prescribed by a GP. If your child is struggling with constipation, visit our baby and toddler collection or speak to your GP for appropriate options.
What happens if I miss a dose of CosmoCol?
If you forget to take a sachet, simply continue with your next scheduled dose at the usual time — do not take a double dose to make up for the one you missed. Missing a single dose is unlikely to cause any problems. Try to take CosmoCol at roughly the same time each day to maintain consistency.
How long can you use CosmoCol sachets for?
CosmoCol is intended for short-term use, typically up to two weeks, without needing to consult a doctor. If your constipation has not improved after two weeks, or if it keeps coming back, you should speak to your GP to rule out an underlying cause. Long-term laxative use should always be supervised by a healthcare professional.
What are the alternatives to CosmoCol sachets?
Other macrogol-based products such as Movicol and Laxido contain the same active ingredient and work in the same way. Stimulant laxatives like senna or bisacodyl work differently by stimulating bowel contractions, but can cause more cramping. You can explore the full range of options in our constipation collection to find what suits you best.
Is CosmoCol safe to use during pregnancy?
Macrogol 3350 is not significantly absorbed into the bloodstream, which is reassuring, but you should still speak to your GP or midwife before using any laxative during pregnancy. Constipation is very common in pregnancy and dietary changes such as increasing fibre and fluid intake are usually recommended first. Your healthcare provider can advise on the safest approach for your individual situation.
Can I take CosmoCol alongside other medicines?
Macrogol 3350 may theoretically affect the absorption of other oral medicines if taken at the same time, so it is advisable to leave a gap of at least two hours between CosmoCol and other medications. No clinically significant drug interactions have been identified at standard doses. Always tell your pharmacist about all medicines, supplements, and herbal remedies you are taking.
What does the latest research say about macrogol for constipation?
Macrogol 3350 is one of the most widely studied and recommended osmotic laxatives in the UK, endorsed by both the NHS and NICE guidelines for the treatment of constipation in adults and children. Clinical evidence consistently shows it is effective and well tolerated compared to other laxative classes. It remains a first-line recommendation for constipation management in primary care settings across the UK.
