Q.Sleeping pills are recommended by doctors to the patients suffering from sleeplessness but it is not advisable to take its doses without consultation with the doctor. Why ?

Sleeping pills are usually tranquilizers (a class of hypnotic/sedative drugs) that act on the central nervous system (CNS) to relieve mental stress, anxiety and insomnia by depressing CNS activity and inducing sleep.

Taking such drugs without a doctor's advice is risky for several reasons:

• Overdose danger — tranquilizers depress the CNS; too high a dose can excessively slow breathing and heart rate, leading to coma or death.
• Dependence/addiction — unsupervised, repeated use can cause the body to develop tolerance, requiring larger doses and leading to psychological/physical dependence.
• Disturbed body mechanism — improper use can interfere with the body's normal biological clock and other regulatory functions, not just sleep.
• Individual variation — the correct drug and safe dosage depend on the patient's age, body weight, other medications, and medical history, which only a qualified doctor can assess.

Identify that sleeping pills are CNS-depressant tranquilizers. Reason about what happens if the dose is not matched to the patient (overdose, dependence, disturbed body rhythm). State that only a doctor can judge the correct drug/dose for a given patient.

• Giving a vague answer like "they are harmful" without naming the specific risks (overdose, CNS depression, dependence).
• Confusing sleeping pills/tranquilizers with antibiotics or antacids.
