Olsar Ch 20/6.25

OLSAR CH 20/6.25

OLSAR CH 20/6.25 is a prescription medication manufactured by TORRENT PHARMACEUTICALS LTD. It is a combination antihypertensive primarily used to manage high blood pressure.

• Composition

  • Each tablet contains Olmesartan Medoxomil 20 mg and Chlorthalidone 6.25 mg.
  • Olmesartan medoxomil is an angiotensin II receptor blocker (ARB) that works by relaxing blood vessels.
  • Chlorthalidone is a diuretic (water pill) that helps remove extra water and certain electrolytes from the body, thereby reducing fluid overload and blood pressure.

• Uses OLSAR CH 20/6.25 is prescribed for the treatment of hypertension (high blood pressure). It is often used when a single medication is not sufficient to control blood pressure effectively. By lowering blood pressure, it helps reduce the risk of associated cardiovascular complications such as heart attack, stroke, and kidney problems.

• Dosage and Administration

  • The typical dosage is one tablet once daily.
  • It can be taken with or without food.
  • Swallow the tablet whole with a glass of water; do not crush, chew, or break it.
  • For consistent blood levels, take it at the same time each day.
  • Due to its diuretic effect, it is generally advised to avoid taking it within four hours of going to bed to prevent frequent urination at night.

• Side Effects

  • Common Side Effects: Headache, nausea, dizziness, fatigue, diarrhea, upset stomach, muscle cramps, weakness, taste change, increased uric acid levels, and electrolyte imbalances.
  • Serious Side Effects: Allergic reactions (rash, itching, swelling), kidney problems, significant electrolyte imbalances (such as low sodium or potassium, or high potassium levels), irregular heartbeat, and, rarely, sprue-like enteropathy leading to severe, chronic diarrhea with substantial weight loss. If persistent or severe, consult a doctor immediately.

• Precautions

  • Contraindications: Do not take OLSAR CH 20/6.25 if you are allergic to its components, have very low blood pressure (hypotension), a recent heart attack, severe kidney or liver disease, jaundice, diabetes, or gallbladder problems. It is also contraindicated if you are pregnant (especially beyond the first trimester) or breastfeeding.
  • Drug Interactions: Inform your doctor about all medications, supplements, and herbal products you are taking. Caution is advised with potassium-containing salt substitutes or supplements, NSAIDs, lithium, and other blood pressure medications (e.g., ACE inhibitors like ramipril or benazepril), as these can increase the risk of side effects like high potassium or kidney issues.
  • Alcohol: Avoid alcohol consumption as it may increase the blood pressure-lowering effects and cause excessive dizziness.
  • Medical Conditions: Use with caution in patients with severe kidney or liver disease, diabetes, gout, or a history of allergies, especially to sulfonamide medicines.
  • Driving: This medication may cause dizziness, so avoid driving or operating heavy machinery if you experience such effects.
  • Do not stop taking the medicine abruptly without consulting your doctor, as this can lead to a dangerous increase in blood pressure.

• Storage Store OLSAR CH 20/6.25 at room temperature, below 25°C, in an airtight container. Keep it out of the sight and reach of children and pets.

What is OLSAR CH 20/6.25 used for?

OLSAR CH 20/6.25 is a combination medication primarily used to treat high blood pressure, also known as hypertension. It is often prescribed when a single medication is not sufficient to control blood pressure. Managing hypertension with this medication helps to reduce the risk of serious complications such as heart attacks, strokes, and kidney problems.

How does OLSAR CH 20/6.25 work?

OLSAR CH 20/6.25 contains two active ingredients: Olmesartan medoxomil and Chlorthalidone.

• Olmesartan medoxomil is an angiotensin receptor blocker (ARB). It works by blocking the action of a hormone called angiotensin II, which normally causes blood vessels to narrow. By blocking this, olmesartan relaxes and widens blood vessels, allowing blood to flow more smoothly and the heart to pump more efficiently, thereby lowering blood pressure.
• Chlorthalidone is a diuretic, often referred to as a "water pill." It works by increasing the amount of salt and water the body removes through urine. This reduces the amount of fluid in the blood, which also helps to lower blood pressure. The combined action of these two medicines provides a synergistic effect to effectively control high blood pressure.

What is the usual dosage of OLSAR CH 20/6.25?

The recommended dosage is generally one tablet per day. It can be taken with or without food, but it is advisable to take it at the same time each day for consistent blood levels of the medication. The tablet should be swallowed whole with a glass of water and not chewed, crushed, or broken. Your doctor will determine the exact dose and duration based on your medical condition and response to treatment.

What are the possible side effects of OLSAR CH 20/6.25?

Common side effects may include dizziness, lightheadedness, headache, nausea, diarrhea, and fatigue. Some patients might also experience muscle cramps, upset stomach, taste changes, increased uric acid levels, or electrolyte imbalances. Less common but potentially serious side effects can include allergic reactions, kidney problems, significant electrolyte imbalances (such as low sodium or potassium), and irregular heartbeat. If side effects persist or worsen, you should consult your doctor.

Is OLSAR CH 20/6.25 safe during pregnancy or breastfeeding?

OLSAR CH 20/6.25 is generally considered unsafe for use during pregnancy, especially after the first three months, as there is definite evidence of risk to the developing baby. It is strongly advised to inform your doctor if you are pregnant, planning to become pregnant, or if pregnancy is detected while taking this medicine.

It is also not recommended for use in breastfeeding mothers because it may be excreted into milk and could potentially accumulate in the infant, particularly newborns or preterm infants. Lactation might also be suppressed.

Can OLSAR CH 20/6.25 be taken with other medications?

OLSAR CH 20/6.25 can interact with several other medications. It is crucial to inform your doctor about all medicines, supplements, or herbal products you are currently taking to avoid potential interactions.

• Aliskiren: Using aliskiren with olmesartan can increase the risk of serious side effects like kidney problems, low blood pressure, and high potassium levels.
• ACE Inhibitors (e.g., Benazepril, Ramipril): Combining with certain ACE inhibitors can also increase the risk of low blood pressure, kidney problems, and high potassium.
• Potassium Supplements/Salt Substitutes: Taking potassium-containing salt substitutes or over-the-counter potassium supplements can lead to high potassium levels in the blood.
• NSAIDs (Non-steroidal anti-inflammatory medicines like ibuprofen, diclofenac): These can reduce the blood pressure-lowering effect of OLSAR CH 20/6.25.
• Lithium: OLSAR CH 20/6.25 may increase lithium levels in the blood, potentially causing toxicity.
• Diabetes medicines (e.g., insulin, metformin): Chlorthalidone can affect blood sugar levels, requiring dosage adjustments of diabetes medications.
• Digoxin: OLSAR CH 20/6.25 may alter digoxin levels.
• Colesevelam: If taking colesevelam, it should be taken at least 4 hours after OLSAR CH 20/6.25.

What precautions should be taken?

• Medical Conditions: Inform your doctor about any pre-existing medical conditions, especially kidney disease, liver disease, heart disease, diabetes, or gout.
• Dehydration: This medicine may cause dehydration. Maintain proper fluid intake and inform your doctor if you experience extreme thirst, very dry mouth, or muscle weakness.
• Dizziness: It may cause dizziness, so get up slowly when rising from a sitting or lying position. Avoid driving or operating heavy machinery if you experience dizziness or fatigue.
• Alcohol: Avoid or limit alcohol consumption as it can worsen side effects like dizziness and low blood pressure.
• Diet: Follow a low-salt diet to help manage blood pressure.
• Regular Monitoring: Regular monitoring of blood pressure, kidney function, and electrolyte levels is recommended during treatment.
• Grapefruit: Avoid consuming grapefruit or grapefruit juice as it may enhance the blood pressure-lowering effects.
• Allergies: Inform your doctor if you are allergic to any components of the medicine or to sulfonamide medicines (due to chlorthalidone).

What happens if a dose is missed?

If you miss a dose of OLSAR CH 20/6.25, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one, as this can lead to low blood pressure.

How should it be stored?

OLSAR CH 20/6.25 should be stored in a cool and dry place, preferably below 25°C, and protected from moisture and light. Keep the medicine out of the sight and reach of children and pets.
