Varför detta händer

You can take paracetamol and quinine together. Always follow the dosage instructions on the packet or as prescribed by your doctor. If you experience unusual side effects like ringing in the ears (tinnitus) or skin rashes, contact your doctor.

Liver health and dosing safety

Never exceed the maximum dose of 8 tablets (500mg each) of paracetamol in 24 hours. Taking too much can cause serious, permanent liver damage that may not show symptoms for several days. Check all other medicines (like cold and flu remedies) to ensure they do not also contain paracetamol.

Heart rhythm disorders (e.g. Long QT syndrome)

Quinine can cause serious, potentially life-threatening heart rhythm problems. Do not take this medicine if you have a history of heart rhythm issues or are taking other medicines that affect your heart rate.

Thrombocytopenia (low blood platelets)

Quinine can cause a dangerous drop in blood platelets. Seek urgent medical help if you notice unexplained bruising, nosebleeds, or purple spots on your skin.

Tinnitus (ringing in the ears) or optic neuritis

Stop taking quinine immediately and seek medical advice if you experience any changes to your hearing (such as ringing) or any sudden changes to your vision.

Alkohol

It is best to avoid or strictly limit alcohol while taking quinine. Both alcohol and quinine can cause dizziness or blurred vision; combining them can make these effects worse and increase the risk of falls or accidents.

Grapefruit juice

Avoid drinking grapefruit juice while taking quinine. Grapefruit juice can increase the amount of quinine in your blood, which makes side effects more likely and can potentially lead to dangerous heart rhythm problems.

Tonic water

Tonic water contains small amounts of quinine. While the levels are low, consuming large amounts of tonic water alongside your medication could potentially increase the risk of side effects.
