Can I take Withania Somnifera with Oxazepam?

Review Withania Somnifera with Oxazepam: possible adverse effects, preparation details, evidence limits, and sources.

Prepared by Dr. Edward M.Kim, PharmD · Clinical Director, SupplementSafety editorial team

Research summary published · Prepared · Editorial update

The short answer

Review ashwagandha before using it with oxazepam. Some preparations can cause drowsiness, and official guidance flags possible sedative interactions.

What this answer covers

Oral Withania somnifera; root-extract sleep findings are not equivalent to all leaves, extracts or mixtures.

Supplement or preparation
Withania somnifera
Medication ingredient
oxazepam

Why a review is warranted

NCCIH describes drowsiness with some ashwagandha preparations and possible interactions with sedatives. Oxazepam already can affect alertness and coordination.

The sleep trial has a clear boundary

A root-extract study reported no adverse events, but excluded regular medication users. It therefore cannot establish safety during oxazepam treatment.

Check formulation and timing assumptions

Bring the plant part, extract, dose and other ingredients to the pharmacist. No universally safe supplement dose or protective separation interval has been demonstrated.

Protect your alertness

Oxazepam can impair coordination and alertness. Avoid driving when affected. Seek urgent help for severe difficulty waking or breathing, and tell the prescriber about all other sedating medicines and alcohol.

Evidence and practical considerations

Side effects & toxicity

Conditional alertness review is supported by supplement guidance and exact oxazepam effects, without a quantitative exact-pair prediction.

Exact scope
Oral Withania somnifera; root-extract sleep findings are not equivalent to all leaves, extracts or mixtures. with Exact oral oxazepam; no blanket benzodiazepine metabolic or route transfer.
Medication form and route
oral; other cannabis routes only if explicitly discussed
Timing or duration
Exact duration and dose depend on source; single-dose and chronic use are distinguished.

What remains uncertain

  • No exact human co-use trial; regular medication users were excluded from the cited root-extract trial.

Factors that may matter: preparation and plant part; dose; other medicines; baseline alertness; clinical indication.

Research conclusion: supported with conditions · Evidence assessment: low

Population: Patients prescribed oral oxazepam.

CNS depression, impaired coordination and alertness can occur; concomitant CNS depressants require caution. Dependence and withdrawal risks require individualized tapering rather than abrupt cessation. A single major inactive glucuronide metabolite is excreted in urine. CYP3A interactions measured with alprazolam cannot simply be assigned to oxazepam.

How this applies: Exact RxNorm ingredient and oral formulation confirmed in original label; use exact indication and metabolic boundaries.

Does not quantify the requested botanical interaction risks, prove every herb is sedating, or establish a protective supplement interval.

Source 2: official guidance

nccih.nih.gov · Source check Sep 10, 2026

Population: People considering the specified supplement.

Some preparations can cause drowsiness; possible interaction with sedatives. Products and studied preparations vary.

How this applies: Preparation-specific context; not a directly measured oxazepam interaction.

No direct oxazepam study; short-term safety observations do not establish long-term safety.

Source 3: randomized placebo-controlled trial

pubmed.ncbi.nlm.nih.gov · Source check Sep 10, 2026

Population: 60 adults enrolled with insomnia and anxiety.

Some sleep outcomes improved; no adverse events were reported. Morning alertness did not differ significantly between groups at ten weeks.

How this applies: Preparation-specific context; not a directly measured oxazepam interaction.

Regular medication users and people with restless legs syndrome or other sleep disorders were excluded. Exploratory study; internal reporting inconsistencies in analysis counts. Cannot extend to oxazepam-treated patients or leaf preparations.
