Uses

  • High blood pressure (hypertension) that is not controlled on the 20 mg dose.
  • Long-term blood-pressure control to reduce the risk of stroke, heart attack and kidney damage.
  • Often combined with amlodipine or hydrochlorothiazide when one medicine is not enough.

How to take it

Take one tablet once a day at the same time, with or without food, swallowed whole with water. This is the higher strength – doctors usually step up to 40 mg only after a few weeks on 20 mg if blood pressure is still high. It is a long-term medicine; your doctor will monitor your blood pressure, kidney tests and potassium. Do not stop on your own. Tell your doctor if you develop severe, persistent diarrhoea with weight loss – a rare gut reaction to olmesartan that settles once it is stopped.

Side effects

Common

  • Dizziness or light-headedness.
  • Headache.
  • Tiredness.
  • Cold or flu-like symptoms, sore throat.
  • Nausea or indigestion.

Serious

Stop and get medical help urgently if you notice any of these.

  • Swelling of the face, lips, tongue or throat (angioedema) – emergency.
  • Severe, long-lasting diarrhoea with weight loss (sprue-like enteropathy) – see a doctor.
  • Muscle weakness or an irregular heartbeat – possible high potassium.
  • Fainting or a sharp fall in blood pressure, especially if dehydrated.

Safety information

Alcohol

Limit alcohol – it adds to dizziness and lowers blood pressure further.

Pregnancy

Must not be taken after the third month of pregnancy and is best avoided throughout – it can seriously harm the baby. Tell your doctor if you are pregnant or planning to be. Not recommended while breastfeeding.

Kidney problems

Tell your doctor about kidney disease; kidney function and potassium need regular checks. Not combined with aliskiren in people with diabetes or kidney problems.

Liver problems

Used with caution in liver disease; the 40 mg dose may be too high for people with liver impairment.

Children

Can be prescribed from age 6 by a specialist; not for children under 1 and not recommended between 1 and 6 years.

Missed dose

Take it as soon as you remember unless the next dose is nearly due – then skip it. Do not take a double dose.

Interactions

  • Potassium supplements, potassium salt substitutes, spironolactone and heparin – raise potassium.
  • Painkillers like ibuprofen, diclofenac and aceclofenac – reduce the effect and can harm the kidneys.
  • Lithium – toxicity rises; blood levels must be measured.
  • Other blood-pressure medicines, including ramipril or aliskiren – only in combination on a doctor's advice.
  • Antacids containing aluminium or magnesium can slightly lower olmesartan absorption – take them a few hours apart.

Frequently asked questions

What is Olmesar 40 used for?

Olmesar 40 contains olmesartan medoxomil 40 mg, the higher strength of this blood-pressure medicine. It is prescribed when 20 mg has not brought blood pressure down enough.

Olmesar 40 vs Olmesar 20 – which do I need?

Doctors start most people on 20 mg and increase to 40 mg if blood pressure stays high after a few weeks. Never move up on your own – the higher dose needs the same kidney and potassium checks.

Can I take Olmesar 40 along with amlodipine?

Yes, this is a very common combination in India and is available as a single tablet (olmesartan + amlodipine). It should be started by your doctor who will monitor for ankle swelling and low blood pressure.

Can I take Olmezest 40 at night?

Yes, any consistent time works. Some doctors prefer night dosing for better overnight control – follow the time your doctor suggests.

Is Olmesar 40 safe in pregnancy?

No. Olmesartan can seriously harm the unborn baby, especially after the third month, and must be stopped as soon as pregnancy is known or planned. Your doctor will switch you to a safer medicine.

Can I drink alcohol with Olmesar 40?

Keep it to a minimum. Alcohol adds to the dizziness and blood-pressure drop, which is more noticeable at the higher dose.

Does olmesartan cause diarrhoea?

Rarely, olmesartan can cause a severe, long-lasting diarrhoea with weight loss, sometimes months or years after starting. If this happens, see your doctor – it resolves once the medicine is changed.

Can I take painkillers with Olmesar 40?

Paracetamol is safe. Avoid regular ibuprofen, diclofenac or other NSAIDs, which reduce its effect and can damage the kidneys when combined.

Is Olmesar 40 a prescription medicine?

Yes. Olmesartan is a Schedule H medicine in India and chemists must see a valid prescription. Regular blood pressure and blood tests are needed during treatment.
