Nu-Seals 300 contains aspirin. Aspirin is used:
If you take aspirin in high doses or over a long period of time, it can irritate your stomach lining. To prevent stomach irritation, these tablets have a special coating (called enteric) so that the aspirin is not released until it has passed through the stomach.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. The effect of treatment may be influenced if aspirin is taken at the same time as some other medicines for:

Tell your doctor that you are taking Nu-Seals 300 if you are to have a urine test, as it can sometimes interfere with the results.
Before using aspirin, you should inform a healthcare professional about the medicines you are taking. If you are using aspirin regularly you should seek advice before taking any other medicine (including other medicines you may have bought).
Pregnant women should not take aspirin during pregnancy unless advised by their doctor. You must not take Nu-Seals 300 if you are in the last 3 months of pregnancy. Regular or high dose aspirin therapy during late pregnancy can cause serious complications in the mother or baby.
