Warnings and precautions
Before starting to use Eziclen, you should consult your doctor if:
- The patient is dehydrated (symptoms may include dry mouth, thirst, headache, dizziness, urinating less often than usual, extreme fatigue, palpitations, and confusion)
- The patient has ever had abnormal sodium or potassium levels in the blood
- The patient has heart disease. Eziclen may affect heart rhythm due to changes in blood salt levels. It may be necessary to monitor the patient during treatment
- The patient has kidney disease (renal failure)
- Dehydration may cause kidney problems (renal failure), which are reversible with proper treatment
- The patient has liver disease
- The patient has disorders related to "uric acid" (gout or other disease)
- The patient has swallowing disorders
- The patient has "reflux", where stomach acid is thrown back into the esophagus
- The patient is physically weakened or in poor health
- The patient has weakened intestinal function (weakened peristalsis)
- The patient has a history of medical conditions or surgical procedures related to the digestive tract, which may predispose to weakened peristalsis of the digestive tract.
If the patient is weakened or elderly (65 years or older), has severe kidney, liver, or heart disease, or is at risk of changes in salt levels in the body (electrolyte disturbances), the doctor may recommend special monitoring of the patient before and after the examination or procedure. The patient should pay special attention to the recommendations mentioned in this part of the leaflet as well as in the "Other medicines and Eziclen" and "How to use Eziclen" sections.
If the patient experiences severe vomiting or symptoms of dehydration (e.g., dry mouth, thirst) after taking this medicine, they should inform their doctor, who will recommend the use of hydrating measures.
If severe or persistent abdominal pain and/or rectal bleeding occur after taking Eziclen, the patient should consult their doctor. During the use of Eziclen, there have been rare cases of colitis (colonic inflammation).
If any of the above points apply to the patient (or in case of uncertainty), the patient should consult their doctor before using Eziclen.
After taking the medicine, the patient will experience frequent loose stools. This is normal and indicates the effective action of the medicine. The patient should stay near a toilet until the effect of the medicine subsides.
The patient should strictly follow the recommendations and drink as much water or clear fluids as needed to avoid dehydration.
Children and adolescents
Eziclen is not intended for use in patients under 18 years of age. The safety and efficacy of this medicine in this patient group have not been established.
Other medicines and Eziclen
The patient should tell their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. This includes medicines available without a prescription and herbal products.
If the patient is taking any other medicines, they should take them one to three hours before taking Eziclen or at least one hour after completing the bowel cleansing process.
This is because the diarrhea caused by Eziclen may flush out other medicines from the body, making them less effective.
Special precautions should be taken in the case of:
- medicines that may affect fluid or salt levels in the blood (such as diuretics, calcium channel blockers, or lithium salts) or medicines that affect heart rhythm.
- oral medicines taken regularly, such as oral contraceptives, antiepileptics, antidiabetics, antibiotics, levothyroxine (a hormone used to treat hypothyroidism), or digoxin (used in heart disease), as Eziclen may delay or completely inhibit the absorption of these medicines, reducing or eliminating their effect.
Pregnancy and breastfeeding
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before using this medicine.
During breastfeeding, the patient should not breastfeed their child for 48 hours after taking the second dose of Eziclen.
Driving and using machines
Eziclen is unlikely to affect the ability to drive or use tools or machines.
