Diarrhoea Treatments & Advice

Rated Excellent based on over 16,000 reviews from Google & Reviews.io

Unsure about a treatment?
Ask our medical team for impartial information and advice about any treatment we provide or medical condition that we treat before you buy.

*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

  • What food should I eat if I have Diarrhoea?

    If you have diarrhoea you should try and eat the following foods:

    • High-energy foods such as fats, yoghurts & cereals. These should be consumed in small portions and often to keep energy levels up.
    • High potassium foods such as lentils, bananas, mangoes & pineapples. These will help to prevent cramps.

    You should try to avoid high fibre and spicy foods as these can worsen diarrhoea. You should drink freshly boiled and cooled water mixed with rehydration sachets and avoid alcohol.

  • How will I know if I am dehydrated?

    Symptoms of early or mild dehydration include:

    • Red, flushed or warm face
    • Extreme thirst, more than normal or unable to drink
    • Dry mouth & tongue
    • Thick saliva.
    • Dry & warm skin
    • Small amounts of dark, yellow urine
    • Dizziness (worse on standing)
    • Weakness
    • Cramping (arms & legs)
    • Drowsy or irritable
    • General feeling of unwell
    • Headaches

    If you recognise any of the early symptoms of dehydration it is important to start to rehydrate yourself using rehydration sachets as soon as possible. Dehydration is a dangerous side effect of diarrhoea that should not be ignored.

  • If I stop drinking water will that stop my Diarrhoea?

    No, under no circumstance should you stop drinking water if you have diarrhoea. It will not help to ease your diarrhoea and it will only increase the risk of dehydration – a potentially dangerous complication.

  • Will Diarrhoea treatment make me constipated?

    No, if used properly diarrhoea treatment should not leave you constipated.

  • Is it normal to experience vomiting and Diarrhoea together?

    You may sometimes experience vomiting and diarrhoea together although this is usually due to an infection, like norovirus. It is important that if your vomiting and diarrhoea last for more than a couple of days, you should see your GP.

Excellent service, thank you! I feel so lucky to have found this pharmacy. I am getting my treatment without needing to go to a GP, as they have their own doctors who assess the symptoms.

You passed with flying colours. I'll definitely recommend you You did absolutely fine! I've never ordered from an online pharmacy before because it's difficult to know which ones are legitimate, but all of your positive reviews made me take the risk, though I only ordered a single product, as a test.
