Important precautions
Pregnancy
Do not take cod liver oil if you are pregnant or planning to become pregnant. It contains high levels of Vitamin A (retinol), which can harm the development of an unborn baby.
Liver disease
You must not exceed the maximum dose of paracetamol, as this can cause serious liver damage. If you have existing liver problems, you must speak to your doctor before use.
Concurrent medication use
Many other medicines (such as cold and flu remedies) also contain paracetamol. Taking more than one product containing paracetamol at the same time can lead to a dangerous overdose.
Food and drink warnings

Can I take Lisinopril and Potassium together?
Taking lisinopril and potassium supplements together can cause the levels of potassium in your blood to become dangerously high (a condition called hyperkalaemia). While your body needs potassium for your heart and muscles to work, too much of it can lead to serious heart rhythm problems or even cause the heart to stop. Symptoms of high potassium can include muscle weakness, tingling sensations, or palpitations, but often there are no symptoms until the level is very high.
