RestoraLAX is a gentle and effective osmotic laxative containing the active ingredient Polyethylene Glycol 3350 (PEG 3350). It works by drawing water into the colon to soften and hydrate the stool, making it easier to pass. The following guide provides general information on its usage for adults, based on official product information and medical resources.

Proper usage and administration

For adults aged 18 and over, follow the instructions provided by your healthcare provider or on the product packaging. It is important not to exceed the recommended amount.

Step-by-step instructions for use

Prepare the product: RestoraLAX comes with instructions on how to measure or prepare a single serving, whether from a bottle or pre-measured packets. Follow these instructions carefully.
Choose your beverage: The powder is tasteless and grit-free, allowing it to be mixed easily into any hot or cold non-alcoholic liquid. Popular options include water, juice, coffee, or tea. The typical amount of liquid used is around 8 ounces (250 mL).
Mix thoroughly: Stir the liquid until the powder is completely dissolved. It is important to ensure there are no clumps before drinking.
Drink immediately: Consume the entire mixture as soon as it is prepared.
Stay hydrated: It is crucial to drink plenty of fluids throughout the day while using this medication to enhance its effectiveness and prevent dehydration.

What to expect when using RestoraLAX

RestoraLAX is not a fast-acting laxative and generally produces a bowel movement within one to three days. This gradual process helps restore your body's natural rhythm without causing the sudden urgency often associated with stimulant laxatives. As your body adjusts, you may experience loose or watery stools. If your stools become too loose, you can temporarily stop taking the medication and restart with a smaller amount once they return to a firmer consistency.

Important precautions and warnings

Duration of use Do not use RestoraLAX for an extended period, such as more than 7 days, unless recommended by a doctor. Extended use can lead to dependency for bowel function.
Consult a doctor before use if you have symptoms of a bowel obstruction (e.g., fever, nausea, vomiting, severe abdominal pain), kidney disease, or are pregnant or breastfeeding.
Take other medications at a different time. RestoraLAX should not be taken within two hours of another medicine, as it may reduce the effectiveness of the other medication.
Stop and see a doctor if you experience rectal bleeding or a worsening of your symptoms. These could indicate a more serious condition.
Be aware of choking risk if using starch-based food thickeners, as RestoraLAX can reduce their effectiveness.
