1. What Cenat is and what it is used for

Cenat belongs to a group of medications called bulk-forming laxatives. These medications work by facilitating the absorption of water by the intestinal bolus, forming a gel that increases the volume and fluidity of the stool.

Cenat is used for:

  • Chronic habitual constipation, or as a result of bed rest after surgical operations, for example, after rectal or anal surgery, due to changes in diet, travel, or prolonged treatment with drastic laxatives.
  • Conditions that involve alternating episodes of diarrhea and constipation (irritable colon, diverticulosis). Regulation of bowel movements in patients with an artificial anus (colostomy).
  • Symptomatic treatment of functional diarrhea and as an additional measure in cases of Crohn's disease.
  • Proctological (rectal) processes such as hemorrhoids, fissures (or anal abscesses), which reduce the pain of defecation and facilitate the evacuation of stool, as it is richer in water.
  • To complete the daily intake of fiber when it is insufficient (weight loss diets and certain metabolic disorders).

2. What you need to know before taking Cenat

Do not take Cenat

  • Maintain adequate hydration with an intake of 1-2 liters of water per day during treatment with Cenat.

Use of other medications

Inform your doctor or pharmacist if you are using or have recently used other medications, including those obtained without a prescription.

Due to the risk of intestinal obstruction, do not take Cenat if you are taking antidiarrheal medications or products that inhibit intestinal motility (diphenoxylate, loperamide, opioids).

Use of Cenat with food and drinks

As a general rule, Cenat should be administered after meals.

In the case of using Cenat as a complementary treatment for obesity, it is useful to take it 30 minutes before main meals to induce a feeling of fullness.

3. How to take Cenat

Take 2 dessert spoons of granules (10 g of granules) at night after dinner. If necessary, you can take an additional spoon in the morning (which would be equivalent to a total of 15 g of granules per day).

In case of diarrhea, take an initial dose of two spoons 3 times a day (30 g of granules/day) for 2 or 3 days and then reduce the dose to one heaped spoon 3 times a day (15 g/day).

4. Possible side effects

Like all medications, Cenat can cause side effects, although not everyone experiences them.

The side effects of this medication are generally mild and transient. At the start of treatment and depending on the dose, some discomfort such as flatulence and a feeling of fullness may appear, which disappear in a few days without needing to stop the medication.

In certain cases, abdominal distension may appear and exceptionally, isolated cases of intestinal, throat, or esophageal obstruction may occur, especially if the granules are ingested without sufficient water.

Occasionally, allergic reactions to Plantago ovatamay occur, mainly due to inhalation of the powder, and isolated cases of anaphylactic reactions may exist. Due to the granule presentation of Cenat, this problem is very unlikely.

If you consider that any of the side effects you are experiencing is serious or if you notice any side effect not mentioned in this package leaflet, inform your doctor or pharmacist.

5. Storage of Cenat

Keep in the original packaging. Keep the bottle perfectly closed. Keep out of the reach and sight of children.
