Why this happens
Both substances affect the central nervous system and can cause dehydration. Acetazolamide changes the chemical balance of your blood (making it more acidic), and alcohol can interfere with the body's ability to regulate this balance, potentially leading to serious metabolic issues.

Patient picks for Drug interactions
Treatment and medication
Can I take Acetaminophen and Levocetirizine together?
Taking paracetamol (acetaminophen) and levocetirizine together is generally considered safe. There are no known major interactions between these two medicines. However, both can occasionally cause drowsiness or tiredness in some people. If you experience these side effects, they may be slightly more noticeable when taking both medicines at the same time.
Treatment and medication
Can I take Desmopressin and Ketoconazole together?
Taking these two medicines together can significantly increase the amount of desmopressin in your blood. 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.
