1. What is Co-Amlessa and what is it used for

Co-Amlessa is used to treat high blood pressure (hypertension). All three active substances help control high blood pressure. Patients already taking perindopril/indapamide and amlodipine in separate tablets can take one Co-Amlessa tablet instead, which contains all three components.
Co-Amlessa is a combination of three active substances: perindopril, indapamide, and amlodipine. Perindopril belongs to a group of medicines called angiotensin-converting enzyme inhibitors (ACE inhibitors).
Amlodipine is a calcium antagonist (belonging to a group of medicines called dihydropyridines).
Indapamide is a diuretic.
In patients with high blood pressure, perindopril and amlodipine cause blood vessels to relax, making it easier for blood to flow through them. Indapamide increases the amount of urine excreted by the kidneys. Each active substance lowers blood pressure, and together they effectively control it.

2. Important information before taking Co-Amlessa

When not to take Co-Amlessa

Warnings and precautions

Your doctor may need to change the dose and/or take other precautions:

Taking Co-Amlessa with food and drink

It is recommended to take Co-Amlessa before a meal.
Patients taking Co-Amlessa should not consume grapefruit juice or grapefruits, as they can increase the levels of the active substance amlodipine in the blood, which can lead to unforeseen intensification of the action of Co-Amlessa, lowering blood pressure.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Inform your doctor about pregnancy, suspected pregnancy, or planned pregnancy. Your doctor will usually recommend stopping Co-Amlessa before planned pregnancy or as soon as pregnancy is detected and will recommend taking another medicine. Co-Amlessa is not recommended during the first trimester of pregnancy and should not be taken after 3 months of pregnancy, as it can seriously harm the baby if taken during this period.

Breastfeeding

It has been shown that small amounts of amlodipine pass into breast milk.
Inform your doctor about breastfeeding or intending to breastfeed. Co-Amlessa is not recommended for breastfeeding women. Your doctor may recommend another medicine if you want to continue breastfeeding, especially if the baby is a newborn or premature.
Consult your doctor immediately.

Driving and using machines

Co-Amlessa does not affect concentration, but dizziness or weakness due to low blood pressure may occur, which can affect the ability to drive and use machines. Do not drive or operate machinery until you know how Co-Amlessa affects you.

Co-Amlessa contains sodium

This medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means it is essentially "sodium-free".

3. How to take Co-Amlessa

Always take this medicine exactly as your doctor or pharmacist has told you. If you are not sure, ask your doctor or pharmacist.
Co-Amlessa is available in the following strengths: 2 mg + 5 mg + 0.625 mg; 4 mg + 5 mg + 1.25 mg; 4 mg + 10 mg + 1.25 mg; 8 mg + 5 mg + 2.5 mg; 8 mg + 10 mg + 2.5 mg.
The recommended dose is one tablet per day. It is recommended to take the medicine in the morning before breakfast.
Swallow the tablet with a glass of water.
Your doctor will decide which dose is suitable for you. Co-Amlessa is recommended for patients already taking perindopril/indapamide and amlodipine in separate tablets.

Overdose of Co-Amlessa

If you have taken more than the prescribed dose, contact your doctor or go to the emergency department of the nearest hospital immediately. The most likely side effect of overdose is low blood pressure. If you experience a significant drop in blood pressure (symptoms such as dizziness or fainting), lie down with your legs raised.
Up to 24-48 hours after taking the medicine, shortness of breath due to excess fluid accumulation in the lungs (pulmonary edema) may occur.

Missed dose of Co-Amlessa

It is important to take the medicine every day, as this ensures the effectiveness of the treatment. If you miss a dose of Co-Amlessa, take the next dose at the usual time.
Do not take a double dose to make up for the missed tablet.

Stopping Co-Amlessa treatment

Since antihypertensive therapy is usually long-term, consult your doctor before stopping the medicine.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
