Quick Answer

Alcohol interacts dangerously with many common medicines. It can increase side effects, reduce medicine effectiveness, or cause serious organ damage. Avoid alcohol during most medication courses.

Paracetamol + Alcohol = LIVER DANGER

Both Paracetamol and alcohol are processed by the liver. Combining them significantly increases the risk of liver damage and liver failure. If you drink regularly, even standard Paracetamol doses can be dangerous. Never take Paracetamol to treat a hangover headache after heavy drinking.

Antibiotics + Alcohol

Metronidazole (Flagyl) and Tinidazole cause severe nausea, vomiting, and flushing with alcohol — the 'disulfiram reaction.' Other antibiotics like Azithromycin won't cause dramatic reactions but alcohol reduces immune function, slowing recovery. Best to avoid alcohol during any antibiotic course.

Blood Pressure Medicines + Alcohol

Alcohol can dangerously lower blood pressure when combined with BP medicines, causing dizziness, fainting, and falls. This is especially dangerous with ACE inhibitors, ARBs, and beta-blockers.

Diabetes Medicines + Alcohol

Alcohol can cause dangerous blood sugar drops (hypoglycemia) when taken with Metformin, Glimepiride, or insulin. It also masks symptoms of low blood sugar, making it harder to recognize a dangerous episode.

Other Dangerous Combinations

Sleeping pills + alcohol: extreme drowsiness, breathing problems. Antidepressants + alcohol: increased depression, drowsiness. Painkillers (NSAIDs) + alcohol: stomach bleeding risk. Antihistamines + alcohol: extreme drowsiness.
