Warnings and precautions

-
If you are taking other medicines such as cardiotonic glycosides, antiarrhythmic drugs, drugs that induce QT interval prolongation, diuretics, corticosteroids, or liquorice root.
-
Must not be used daily over a prolonged period.
-
Abuse may cause diarrhoea, resulting in loss of fluid and electrolytes (mainly a decrease in potassium).
-
Long-term abuse may worsen constipation.
-
Chronic use may lead to pigmentation of the colon (pseudomelanosis coli), which is harmless and resolves upon discontinuation of treatment.
-
If you need to take laxatives frequently, the underlying cause of constipation should be investigated.
Children and adolescents
Do not administer to children under 12 years of age.
Use of LINEASUL with other medicines
Inform your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines.
Prolonged use of laxatives may reduce potassium levels, which could enhance the effects of other medicines used for the heart (antiarrhythmics, diuretics, corticosteroids and/or liquorice root).
Administration is not recommended in patients treated with cardiotonic glycosides (drugs regulating cardiac activity) and antiarrhythmic drugs (e.g.: quinidine), as their absorption may be altered.
The effect of this medicine on intestinal transit could alter the levels of other medicines taken concomitantly by oral route.
Taking LINEASUL with food and drink
Food and drink do not influence the effect of the medicine.
Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.
This preparation is excreted in small amounts in breast milk; although there are no data on possible laxative effects in infants, its use is not recommended under these circumstances.

No effects on the ability to drive or use machines have been reported.
3. How to take LINEASUL
Follow exactly the instructions for administering this medicine as described in this leaflet or as directed by your doctor, pharmacist, or nurse. If in doubt, consult your doctor or pharmacist.
LINEASUL is administered orally.
The recommended dose is: 1 sachet per day, prepared as an infusion (herbal tea), preferably before going to bed.
The lowest effective dose should be used. Generally, it will be sufficient to take one infusion (prepared with one tea bag) two or three times per week during treatment.
Each 1.4 g tea bag contains approximately 15.8 mg hydroxyanthracene glycosides expressed as sennoside B and 11.9 mg hydroxyanthracene glycosides expressed as glucofrangulins A.
The recommended maximum daily dose of hydroxyanthracene derivatives is 30 mg, equivalent to one sachet per day.
The laxative effect usually occurs 6 to 12 hours after oral administration.
Treatment should be short-term, with a maximum recommended duration of 6 days.
If symptoms persist after 4 days of treatment, consult your doctor or pharmacist.
If you feel that the effect of LINEASUL is too strong or too weak, inform your doctor or pharmacist.
Use in children and adolescents
Do not administer to children under 12 years of age.
The recommended dose for adolescents is the same as for adults.
If you take more LINEASUL than you should
Ingestion of doses much higher than recommended may cause excessive intestinal activity, resulting in abdominal pain, spasms, and severe diarrhea with loss of water and electrolytes. If the electrolyte imbalance is severe, it may lead to confusion, cardiac arrhythmia, muscle cramps, fatigue, or weakness, which may be more pronounced in elderly patients. However, the risk of intoxication from consuming herbal infusions is limited.
If you have taken more LINEASUL than you should, consult your doctor or pharmacist, or contact the Toxicology Information Service at telephone number 91 562 04 20, indicating the medicine and the amount taken.
If you forget to take LINEASUL
Do not take a double dose to make up for a missed dose.
Additional information on constipation treatment
Although bowel habits vary among individuals, constipation can be considered present when more than 3 days pass without a bowel movement, or when the usual pattern of defecation is temporarily interrupted. Constipation may also be defined by infrequent or hard stools, accompanied by pain during defecation.
Constipation frequently occurs due to lack of physical activity, insufficient fluid intake, or consumption of low-fiber meals. Therefore, it is important to follow these recommendations to prevent constipation, which may help you avoid the need for laxatives:
-
Modify your diet by including fiber-rich foods such as fruits, vegetables, legumes, etc.
-
Drink plenty of water.
-
Avoid a sedentary lifestyle by engaging in regular physical exercise.
-
When you feel the urge to defecate, do not delay it.
-
Try to establish a regular time for bowel movements each day.
-
Allow yourself enough time so that defecation can occur without rushing.
4. Possible adverse effects
Like all medicines, this medicine can cause adverse effects, although not everybody will experience them.
- Hypersensitivity reactions (allergy) may occur.
- At the beginning of treatment, and depending on the dose, some discomforts may appear such as flatulence (gas), intestinal spasms, or pain, which disappear after a few days without the need to discontinue treatment.
- A yellowish or reddish-brown discoloration of the urine may occur (depending on the pH), which has no clinical significance.
