Timing

Take Diazepam as prescribed. Glycine and taurine have calming GABA-ergic properties that may amplify sedation — use caution and take at separate times. L-theanine promotes relaxation through a different mechanism and is generally safe. Avoid high-dose GABA supplements alongside benzodiazepines.

Risk factors

Higher risk for: elderly (fall risk, oversedation), those with respiratory conditions, concurrent opioid or alcohol use, liver impairment, history of substance use disorder, or those on multiple CNS depressants.

Watch for: profound drowsiness, slowed reflexes, impaired coordination, confusion, memory problems, slurred speech, or mood changes. Avoid driving or operating heavy equipment. When to seek emergency help: Severely slowed or stopped breathing, inability to be woken, severe confusion, fainting, or paradoxical agitation. Never combine with alcohol. Do not stop benzodiazepines abruptly — taper under medical supervision.

What to tell your doctor

No urgent discussion needed, but keep your provider informed. Say: "I take Diazepam alongside L-Tryptophan — anything I should know?"

Safer alternatives
