Olmesar Ch 20 Tablet 15 is used for managing the following conditions:

High blood pressure (Hypertension)
Initial therapy with Olmesar Ch 20 Tablet 15 is recommended for patients who likely require multiple medications to control their blood pressure.
Second-line treatment when blood pressure isn't adequately controlled by olmesartan alone.

Here's how you should take Olmesar Ch 20 Tablet 15:

Swallow the tablet whole with a glass of water.
Do not chew, divide, or crush the tablet.
This medicine can be taken with or without food.
Never exceed the recommended dose without consulting your doctor.
Do not abruptly stop taking this medicine; always consult your doctor first.

Olmesar Ch 20 Tablet 15 is taken orally.

Olmesar Ch 20 Tablet 15 may lead to the following side effects:

Dizziness
Headache
Fatigue
Nausea
Hyperuricemia: This is a condition where there is an excessive amount of uric acid in your blood. It can cause gout or kidney stones.
Hypokalaemia: This term refers to lower-than-normal levels of potassium in your bloodstream.
Hyponatraemia: This means that the level of sodium in your blood is lower than normal.
Hypochloremia: In this condition, there is a low level of chloride in your blood.
Impotence

Managing the Side Effects:

Most side effects are temporary and generally harmless, which resolve upon discontinuing the use of Olmesar Ch 20 Tablet 15. However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor.

Here are some tips to manage two common side effects:

Nausea: You can try taking Olmesar Ch 20 Tablet 15 with a light meal or snack.
Fatigue: If this medicine makes you feel tired during the day, consider taking it in the evening before going to bed.

Olmesar Ch 20 Tablet 15 comprises two active ingredients that work together in different ways:

Chlorthalidone (12.5 mg): As a thiazide-like diuretic, chlorthalidone works on the kidneys to increase the excretion of sodium and water. This action reduces blood volume, leading to a decrease in cardiac output and consequently a reduction in blood pressure.
Olmesartan medoxomil (20 mg): This ingredient is an angiotensin II receptor blocker (ARB). By selectively blocking angiotensin II's binding to AT1 receptors in the vascular smooth muscle, olmesartan medoxomil prevents the blood pressure-increasing effects of angiotensin II. As a result, it causes blood vessels to relax, allowing blood to flow more easily and thus lowering blood pressure.

Pregnancy

Olmesar Ch 20 Tablet 15 is contraindicated during the latter half of pregnancy. If you are pregnant or planning to conceive, ask your doctor before starting this medicine.

Breastfeeding

Caution is advised before taking Olmesar Ch 20 Tablet 15 while breastfeeding. You should consult your doctor to understand the potential risks and benefits.

Alcohol

Intake of alcohol may intensify the blood pressure-lowering effects of this medicine and increase the risk of orthostatic hypotension (sudden drop in blood pressure when standing). It's best to consult your doctor on this.

Liver

If you have liver health issues, you need to exercise caution while taking Olmesar Ch 20 Tablet 15. Discuss your liver health with your doctor before starting this medicine, as it may affect liver function.

Kidney

Olmesar Ch 20 Tablet 15 should be used with caution if you have kidney problems. Discuss these concerns with your doctor before starting this medicine.

Using Machines & Driving

As dizziness is a common side effect of Olmesar Ch 20 Tablet 15, caution is advised when driving or operating machinery until you know how this medicine affects you.

Allergy

This medicine is contraindicated if you have an allergy to any component of Olmesar Ch 20 Tablet 15 or sulfonamide-derived drugs. Always let your doctor know about your allergies before starting on a new medication.

Children

Olmesar Ch 20 Tablet 15 is intended for use in adults. Caution should be exercised if considering giving this medicine to children under 18 years. Always consult a doctor before providing any medication to a child.

Older Patients

Older patients should use Olmesar Ch 20 Tablet 15 under medical supervision. They may be more susceptible to its side effects, especially if they have liver or kidney issues or are on other medication. Your doctor will guide you based on your health status.

Drug-Drug Interactions

Olmesar Ch 20 Tablet 15 interacts with the following medicines:

Lithium: When taken together with Olmesar Ch 20 Tablet 15, lithium levels in your blood could rise, potentially leading to lithium toxicity.
Non-steroidal Anti-Inflammatory Drugs (NSAIDs): Medicines like ibuprofen and naproxen could potentially reduce the blood pressure-lowering effect of Olmesar Ch 20 Tablet 15 and increase the risk of kidney problems.
Dual blockade of the Renin-Angiotensin system: Medicines like enalapril or lisinopril may interact with Olmesar Ch 20 Tablet 15, potentially leading to an increased risk of low blood pressure, kidney problems, and high potassium levels in your blood.
Corticosteroids and ACTH: Medicines like prednisolone or corticotropin can intensify the loss of potassium from your body when taken with Olmesar Ch 20 Tablet 15.
Alcohol, barbiturates, or narcotics: These substances can boost the effect of lower blood pressure when combined with Olmesar Ch 20 Tablet 15.

Drug-Food Interactions

There are no specific food interactions known with Olmesar Ch 20 Tablet 15.

Drug-Disease Interactions

Olmesar Ch 20 Tablet 15 interacts with the following diseases:

Liver disease: If you have liver disease, you should exercise caution as Olmesar Ch 20 Tablet 15 could worsen your condition.
Kidney disease: Patients with kidney disease might experience more side effects due to increased levels of this medicine in their body.
Gout: If you have gout, you may experience increased uric acid levels due to this medicine.

Daily Dose

The daily dose of Olmesar Ch 20 Tablet 15 should be as prescribed by your doctor. The dosage might change based on individual factors like how severe your condition is and how you respond to treatment. It's crucial to stick to the prescribed dosage and avoid exceeding it without consulting your doctor.

Over Dose

If you accidentally take more than the prescribed dose of Olmesar Ch 20 Tablet 15, you may experience symptoms such as feeling dizzy or excessively tired. In such a situation, it's important to inform your doctor.

Missed Dose

If you forget to take your scheduled dose of Olmesar Ch 20 Tablet 15, take it as soon as you recall. However, if it's nearly time for your next dose, skip the one you missed and go back to your regular schedule. Never double up on doses without consulting with your doctor.

Store Olmesar Ch 20 Tablet 15 at room temperature, ideally between 20 °C and 25 °C.
Keep the medicine away from excessive light and moisture.
Always maintain it safely out of children's reach.
Remember to use the tablet before its expiration date.

Reduce your salt intake: Consuming less salt can help manage high blood pressure, which is what Olmesar Ch 20 Tablet 15 helps in controlling.
Stay hydrated: Dehydration can affect your blood pressure and kidney function. Make sure you drink plenty of fluids throughout the day.
