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 20 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 20 mg Tablet

Take it at the same time every day to help you remember to take it. It can make you feel dizzy for the first few days. Rise slowly if you have been sitting or lying down for a long time. Your doctor may get regular tests done to monitor the level of urea, creatinine, and potassium in your blood. Avoid taking anti-inflammatory medicines such as ibuprofen along with this medicine without consulting your doctor. It may increase the level of potassium in the blood. Avoid taking potassium supplements and eating potassium-rich foods such as bananas, fruit juice, coconut water, and broccoli. Consult your doctor if you are pregnant or breastfeeding. Do not stop taking it suddenly without talking to your doctor.
