Movicol is a medication indicated for the treatment of chronic constipation and more severe cases of fecal impaction. It is available as an oral solution in ready-to-drink sachets, which are taken directly without needing to be diluted in water. Its active ingredient, macrogol 3350, increases the water content in the intestine, making stools softer and easier to pass.
How does Movicol work?
The main ingredient in Movicol is an osmotic laxative. This means it draws water into the intestine, rehydrating the stool and helping it move more naturally. It is not a stimulant laxative, so its effect is primarily based on softening the stool and promoting gentler bowel movements.
In addition, it contains electrolytes such as sodium and potassium, which help maintain the balance of mineral salts while normalizing intestinal transit.
Main indications for Movicol
Movicol is indicated for the treatment of chronic constipation in adults and adolescents over 12 years of age. It is also used for fecal impaction, when there is a significant accumulation of stool in the rectum. In children under 12 years of age, it should only be used if prescribed by a pediatrician and with the formulation specifically formulated for their age.
The usual presentation includes sachets of ready-to-drink oral solution. For chronic constipation, the dose is usually 1 to 3 sachets per day, adjusting the amount according to the response and always following the doctor's instructions or the package leaflet.
In cases of fecal impaction, higher doses may be used, up to 8 sachets per day for a short period, usually up to 3 days and under medical supervision.
Each sachet is taken directly, without needing to be diluted in water or mixed. It can be taken at any time of day, although many people prefer to take it in the morning. The laxative effect is usually noticeable after 1 or 2 days of treatment.
Precautions and warnings
Before using Movicol, it is advisable to consult your doctor if you have heart failure, high blood pressure, kidney problems, a history of macrogol intolerance, or serious intestinal disorders such as ulcerative colitis, Crohn's disease, or toxic megacolon.
Furthermore, its use should not be prolonged beyond the indicated time without a new medical evaluation, because it could mask other gastrointestinal problems.
Possible side effects
Movicol is generally well tolerated. Still, some people may feel mild abdominal discomfort Mild side effects include bloating, flatulence, nausea, very loose stools, or diarrhea, especially if the dose is high.
These effects usually improve by reducing the dose or spacing out the doses, but if they persist it is important to consult a healthcare professional.
If you don't notice any improvement after several days of use at the recommended dose, it's advisable to consult a healthcare professional instead of increasing the dose yourself. It may be necessary to review the diagnosis or adjust the treatment.
Price and presentations available
Movicol is sold in packs containing varying numbers of sachets, such as 20, 30, or more. In Spain, it is a prescription medication, and its price can vary depending on the number of sachets, the country, and the pharmacy, so it is advisable to check the current price at the point of sale.
Although it can be purchased without a prescription in some places, prolonged self-medication without the advice of a healthcare professional is not recommended.
