Situation: A 38-year-old woman with bipolar I disorder is admitted to the psychiatric ward of a provincial hospital. The ward follows the Mental Health Act (Republic Act [RA] 11036). On admission she is calm and oriented, and the psychiatrist documents that she has decision-making capacity. She refuses the oral olanzapine just prescribed, saying it made her gain weight before. There is no psychiatric emergency. What should the nurse do?

Under RA 11036, every service user is presumed to have legal capacity, written informed consent is required before treatment, and the service user may refuse or withdraw consent. Treatment without consent is allowed only during a psychiatric or neurologic emergency or while decision-making capacity is impaired. Neither applies here, so the nurse withholds the drug and informs the psychiatrist, who can discuss alternatives with her.

Legal Framework Under RA 11036
The Philippine Mental Health Act establishes that every service user is presumed to have legal capacity unless proven otherwise. This means the patient’s refusal of olanzapine cannot be overridden simply because she is admitted to a psychiatric ward. Admission does not equal consent to every prescribed medication. Written informed consent is required before treatment, and the patient retains the right to refuse or withdraw consent at any time.

Treatment without consent is permitted only in two narrow situations: a psychiatric or neurologic emergency, or documented impairment of decision-making capacity. In this scenario, the psychiatrist has already documented that the patient has decision-making capacity, and there is no psychiatric emergency. Therefore, neither exception applies.

Watch out! Option 1 is incorrect because obtaining a family member’s consent does not replace the patient’s own consent when she has capacity. Option 2 is incorrect because admission does not imply blanket consent to treatment. Option 4 is incorrect because giving even one dose without consent violates the patient’s legal right to refuse.

Clinical Reasoning and Nursing Action
The correct nursing action is to hold the dose and inform the psychiatrist of the refusal. This respects the patient’s autonomy while maintaining communication with the prescribing physician, who can then discuss alternative medications or approaches with her. The nurse does not force, hide, or delay reporting the refusal.

The patient’s stated reason for refusal—weight gain from prior olanzapine use—is a valid clinical concern, not a sign of impaired judgment. In bipolar I disorder, metabolic side effects such as weight gain are well documented with olanzapine, and patients often have legitimate preferences about medication tolerability. Acknowledging this concern is part of patient-centered care.

Shared Decision-Making in Psychiatric Wards
Recent qualitative evidence from psychiatric nurses highlights that shared decision-making (SDM) is increasingly promoted in mental health care, but its implementation in closed wards is complicated by fluctuating capacity, safety concerns, coercion, and family involvement ^[1]. Nurses in that study described tensions between respecting patient autonomy and fulfilling clinical responsibility, especially when patients refuse medications that staff believe are necessary.

In this scenario, however, the patient’s capacity is documented and stable, and no emergency exists—so the balance clearly favors honoring her refusal. The nurse’s role is not to persuade or override, but to document the refusal, hold the medication, and notify the psychiatrist so that a collaborative discussion about alternatives can occur.

Key point! A patient with decision-making capacity may refuse any treatment, even if the refusal seems medically unwise. The nurse’s duty is to respect that refusal, document it, and communicate it to the prescriber—not to administer the medication covertly or seek substitute consent from relatives ^[1].
