Composition of Olmat 20 Ct Tablet
Olmat 20 Ct Tablet contains Olmesartan Medoxomil (20mg) + Chlorthalidone (12.5mg). It belongs to the Angiotensin receptor blocker / ACE inhibitor and Water tablet class of medicines.
Uses of Olmat 20 Ct Tablet
- High blood pressure
- Heart failure
- Diabetic kidney disease
- Fluid retention
Benefits of Olmat 20 Ct Tablet
- In High blood pressure
- Olmat relaxes and widens your blood vessels so the heart pumps against less resistance. Lowering blood pressure cuts the risk of stroke, heart attack and kidney damage, even though you will not feel it working.
- In Heart failure
- Olmat eases the load on a weak heart so it pumps more efficiently, which reduces breathlessness and swelling and lowers the chance of a hospital admission.
- In Diabetic kidney disease
- Olmat reduces the pressure inside the kidneys' filters and cuts the protein leaking into the urine, slowing the kidney damage that diabetes causes.
- In Fluid retention
- Olmat makes you pass more urine so that trapped fluid leaves the body, relieving swelling and the heaviness and discomfort that go with it.
How Olmat 20 Ct Tablet works
This medicine combines 2 active ingredients: Olmesartan and Chlorthalidone. Olmesartan relaxes and widens your blood vessels by blocking a hormone that narrows them, so your heart does not have to push as hard and your blood pressure falls. Chlorthalidone helps your kidneys remove surplus salt and water, which reduces swelling and lowers blood pressure.
How to take Olmat 20 Ct Tablet
Swallow the tablet whole with a glass of water. Do not chew, crush or break it unless your doctor has told you to. Take it with or without food, at the same time each day. Taking it at about the same time each day helps you remember. Follow the dose and the duration written on your prescription.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Missed dose and overdose
If you miss a dose
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
If you take too much
An overdose of this medicine can cause a severe fall in blood pressure, with dizziness, fainting and a fast or slow pulse. It can cause severe dehydration, a sharp fall in blood pressure and dangerous salt imbalances. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Warnings and precautions
Stand up slowly for the first few days — dizziness on rising is common when you start or your dose goes up. Stop and seek urgent care if your lips, tongue, face or throat swell, or you have difficulty breathing. A persistent dry, tickly cough can be caused by the ACE inhibitor group; tell your doctor rather than stopping on your own, as an alternative exists. Your doctor will check your kidney function and potassium after starting and after any dose change. Do not use salt substitutes containing potassium without asking your doctor. Take it in the morning so that passing urine does not disturb your sleep. Your doctor will check your salts and kidney function with blood tests — do not skip them. Report muscle cramps, marked weakness, confusion or an irregular heartbeat; these can be signs your potassium or sodium has fallen. In hot weather or during an illness with vomiting or loose motions, tell your doctor — you may become dehydrated quickly.
Do not take Olmat if
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Must not be used in pregnancy — it can seriously harm the developing baby. Not for people with narrowing of both kidney arteries, or a history of swelling of the face and throat caused by this group of medicines. Not for people who are unable to pass urine, or who are severely dehydrated.
Interactions with other medicines
Anti-inflammatory painkillers reduce the effect and can harm the kidneys when combined. Potassium supplements, potassium-sparing water tablets and salt substitutes can push potassium too high. Lithium levels rise when taken with these medicines. Anti-inflammatory painkillers blunt the effect and can strain the kidneys. Lithium and digoxin levels are affected; tell your doctor if you take either. Potassium-sparing types must not be combined with potassium supplements without supervision.
How to store Olmat 20 Ct Tablet
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
