Psychiatric Medication Informed Consent in California: The Basics

By CALMN · August 2026

One of the most common sources of confusion for families is a simple question: can someone in a mental health crisis refuse medication? The short answer is usually yes — a diagnosis or a hospitalization does not, by itself, take away a person's right to make decisions about their own medical care. Here's how California's rules actually work.

The general rule: adults have the right to refuse

Under California law, a mentally competent adult has the right to accept or refuse medical treatment, including psychiatric medication — even while hospitalized, and even while on a psychiatric hold. Being on a 5150 or 5250 hold controls where a person can be for evaluation and treatment; it does not, by itself, authorize forced medication.

Voluntary vs. involuntary patients

For a voluntary patient (someone who agreed to be admitted), ordinary informed-consent rules apply, just as they would for any hospital patient: the care team explains the diagnosis, the proposed medication, the risks and benefits, and reasonable alternatives, and the patient decides.

For a patient on an involuntary hold, the same general right to refuse applies — but if the treatment team believes medication is medically necessary and the patient continues to refuse, California uses a specific legal process, called a capacity hearing or "Riese hearing," to resolve the disagreement.

The emergency exception

None of this applies in a true emergency. If a person poses an immediate danger to themselves or others in the moment, clinicians can administer medication without a hearing or advance consent. This emergency exception is narrow — it covers the immediate crisis, not ongoing or planned treatment over a patient's objection.

What "informed consent" actually requires

A person doesn't need to be symptom-free to have capacity to consent — capacity is about whether they can understand this information and reason through it, not whether their choice matches what the care team recommends.

A special category: electroconvulsive therapy (ECT)

ECT is treated differently from medication under California law, with its own stricter consent and review requirements — including, in most cases, a formal court process regardless of capacity. A Riese hearing does not authorize ECT; it applies specifically to psychiatric medication.

What this means for families

What helps: If your loved one is refusing medication, resist the urge to pressure them directly. Instead, ask the care team what specifically is driving the refusal — side effect fears, past bad experiences, or genuine disagreement with the diagnosis are all common, and each points to a different way to help.

The bottom line

California law tries to strike a balance: mental illness alone doesn't erase someone's right to direct their own medical care, but the law also provides a path forward when a person's illness has genuinely taken away their ability to make that decision. Knowing which situation applies helps families understand what's actually happening — and what their loved one's rights still are.
