Antiepileptics:
Carbamazepine, phenobarbital, phenytoin and primidone can reduce the effects of paracetamol and increase the risk of hepatotoxicity.

Uricosurics:
Probenecid can reduce the loss of paracetamol from the body.
Caffeine:
Antibacterials: Some quinolone antibiotics, including enoxacin, pipemidic acid and ciprofloxacin can reduce the clearance of caffeine and prolong its plasma half-life.
Antidepressants:
Fluvoxamine can reduce the clearance of caffeine and increase its stimulant and side effects.
Antiepileptics:
Phenytoin may increase the clearance of caffeine.
Antipsychotics:
Caffeine may increase serum clozapine levels.

Epidemiological studies on neurodevelopment in children exposed to paracetamol in utero show inconclusive results. If clinically needed, paracetamol can be used during pregnancy however it should be used at the lowest effective dose for the shortest possible time and at the lowest possible frequency.
Paracetamol is excreted in breast milk but not in a clinically significant amount. Available published data do not contraindicate breast feeding.
Caffeine:
Taken during pregnancy it appears that the half-life of caffeine is prolonged. Caffeine crosses the placenta, and foetal blood and tissue levels similar to maternal concentrations are achieved. This is a possible contributing factor in hyperemesis gravidarum.
Cardiac dysrhythmias have been noted in the foetuses […]
