How Olsertain 40 mg Tablet works

How to take Olsertain 40 mg 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

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.

Do not take Olsertain 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.

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.

How to store Olsertain 40 mg Tablet

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Olsertain 40 mg Tablet

Blood pressure medicines work only while you take them — do not stop because you feel well. Tell your doctor at once if you become pregnant or are planning a pregnancy. Keep a home blood-pressure record if your doctor has asked for one.
