What this interaction means in plain words
Estazolam and Secobarbital can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens

What to do
Avoid combining two hypnotics where possible; if needed use the lowest doses and monitor sedation and breathing.
