I took 8mls oxycodone hydrochloride which is prescribed by my doctor along with 4 solpdeine by mistake. is this dangerous? my husband is worried.

Accidental overdose: By "solpdeine" did you mean zolpidem ? In Any case it depends on the milligrams oxycodone oral usually is 5-10 mg per 5 mililiter and depends how tolerant you are to the medication ( in other words how long you been taking it) . If indeed it was Zolpidem ( Ambien ) that was too much however most likely you will be overly sleepy for a few hours , but if breathing is difficult further attention
