What is Gialax?

Gialax is a type of laxative that works by drawing water into the colon to help soften stools and promote regular bowel movements. It is commonly used for short-term relief of occasional constipation.

In some cases, Gialax may be recommended for other purposes not outlined in this leaflet. Always follow the advice of your doctor or pharmacist.

Side Effects

Seek immediate medical help if you experience any of the following:

• Allergic reactions such as rash, swelling (face, lips, tongue, throat), or difficulty breathing
• Severe or bloody diarrhoea
• Rectal bleeding or blood in stools
• Persistent or worsening stomach pain

Common side effects may include:

• Bloating or abdominal discomfort
• Gas or flatulence
• Dizziness
• Increased sweating

This list is not exhaustive. Report any unexpected effects to your doctor or pharmacist. In the UK, side effects can be reported via the Yellow Card Scheme.

Warnings

Do not take Gialax if you have a known blockage in your bowel or intestines. Doing so may lead to serious or life-threatening side effects.

Avoid using Gialax more than once a day and do not continue using it for more than 7 days without medical advice. If your symptoms persist, speak to your GP.

Before Taking

Before using Gialax, let your doctor or pharmacist know if you:

• Are allergic to polyethylene glycol or any ingredients in the formulation
• Have a known or suspected bowel obstruction
• Are experiencing unexplained stomach pain, nausea or vomiting
• Have inflammatory bowel conditions such as ulcerative colitis
• Have a history of eating disorders like anorexia or bulimia
• Have kidney problems
• Have had recent changes in bowel habits lasting longer than 2 weeks

Pregnancy and Breastfeeding:

Gialax is not known to be harmful during pregnancy, but you should inform your GP if you are pregnant or trying to conceive. It is also unclear whether the medicine passes into breast milk. Discuss with your doctor if you are breastfeeding.

What to Avoid

While using Gialax, keep the following precautions in mind:

• Avoid taking other laxatives unless advised by your doctor, as this may increase the risk of dehydration or diarrhoea.
• Do not exceed the recommended dose; using it more than once a day or longer than 7 days may cause serious side effects.
• Avoid delaying bowel movements once you feel the urge, as this can worsen constipation.
• Limit caffeine and alcohol if advised, as they can contribute to dehydration.
• Do not mix Gialax with milk unless your healthcare provider says it’s safe—water or juice is typically preferred.

Always follow your doctor or pharmacist’s guidance regarding food, drink, and activity while taking this medicine.

Interactions

Tell your GP or pharmacist about all the medicines you are currently taking, including prescriptions, over-the-counter remedies, vitamins, and herbal supplements. While Gialax is not known to cause major interactions, it’s best to be cautious.

Dosage

Always take Gialax exactly as instructed by your healthcare provider or follow the label on the packaging.

To prepare a dose, use the marked cap to measure the correct amount of powder. Mix it into 120–240 ml (4–8 oz) of cold or hot fluid such as water, juice, tea, or coffee. Stir well and consume immediately. Do not store the mixed solution for later use.

A bowel movement typically occurs within 1 to 3 days. Loose or watery stools are normal during use.

Do not exceed the recommended frequency—once daily. Contact your GP if constipation continues after 7 days of treatment.

Storage:

Keep Gialax at room temperature, away from heat and moisture.
