Why this happens
Aspirin belongs to a group of medicines called NSAIDs. These can interfere with chemicals in the body called prostaglandins, which help keep blood vessels relaxed. By reducing these chemicals, aspirin can cause the body to retain a bit more salt and water, which slightly pushes blood pressure up, working against the metoprolol.

Treatment and medication
Can I take 7.5mg and Medikinet together?
Taking Zopiclone and Medikinet (methylphenidate) together can cause a 'tug-of-war' effect in your body. Medikinet is a stimulant designed to wake you up and help you focus, while Zopiclone is a sedative designed to make you sleepy. Taking them at the same time can make both medicines less effective. Additionally, while Medikinet is active, it may be harder for you to fall asleep, even after taking Zopiclone. In some cases, mixing stimulants and sedatives can lead to unpredictable effects on your coordination, heart rate, or mental state (such as feeling confused or agitated).

Treatment and medication
Can I take Desmopressin and Ketoconazole together?

This can lead to your body holding onto too much water, which can cause a dangerous drop in your blood salt levels (hyponatraemia). Symptoms to watch for include severe headache, nausea, vomiting, confusion, or feeling very drowsy.
