L-Tryptophan

Name	L-Tryptophan
Uses	Essential amino acid used to support serotonin synthesis, mood regulation, and sleep quality. May assist in reducing symptoms of mild anxiety, stress, and sleep disturbances. Commonly used in wellness IV protocols for mood support, stress management, and sleep optimization.
Route Of Administration	Intravenous (IV)
Frequency Of Use	Typically administered once weekly for mood and sleep support. In intensive stress management or sleep optimization protocols, may be given twice weekly for 4 to 6 weeks, followed by reassessment. Long-term use should be reviewed every 8 to 12 weeks.
Concentration(s)	Common compounded concentrations range from 50 mg/mL to 100 mg/mL.
Maximum Dosage (Day, Wk) (g/mL)/mL	Maximum dose per infusion: 1,000 mg (1 g). Maximum weekly dose: 2,000 mg (2 g). Higher doses are not recommended for elective wellness patients without documented medical justification.
Contraindications	Severe hepatic or renal impairment. Known hypersensitivity to L-tryptophan or any component of the formulation. Patients currently taking serotonergic medications (SSRIs, SNRIs, MAOIs) due to risk of serotonin syndrome. Pregnancy and breastfeeding unless cleared by OB provider. Active or unstable mood disorders unless managed by a mental health provider.
Possible Side Effects	Nausea, drowsiness, headache, or flushing during infusion. Mild dizziness. Injection site irritation. Rare: allergic reactions (rash, itching, hypersensitivity).
Compatibility With Other Drugs	Compatible with normal saline and D5W. Should not be mixed directly with calcium-containing solutions. May be combined with other amino acids or vitamins in comprehensive wellness IVs, but compatibility must always be verified prior to mixing.
Allergies	True allergy to L-tryptophan is rare. Reactions are more likely related to preservatives or stabilizers in compounded formulations.
Administration Time	Typical infusion time: 30 to 45 minutes for doses up to 1,000 mg. Slower infusion may improve tolerability in sensitive patients.
IV Dosing	For mood and sleep support: 500 mg to 1,000 mg IV once weekly. For intensive stress management or sleep optimization: 1,000 mg IV once or twice weekly for 4 to 6 weeks, followed by reassessment. Long-term use requires periodic clinical review.
IM/Push	May be given as a slow IV push for doses up to 500 mg over 5 to 10 minutes. Higher doses should be given via drip for better tolerability. IM administration is not recommended due to local irritation and inconsistent absorption.
What To Do If Adverse Reaction Occurs	1. Stop the infusion immediately. 2. Assess vital signs (blood pressure, heart rate, oxygen saturation). 3. If nausea, dizziness, or flushing occurs, place the patient in a comfortable position and provide oral fluids if tolerated. 4. For allergic reactions (rash, itching, shortness of breath), administer antihistamines and consider epinephrine if severe. 5. If serotonin syndrome is suspected (agitation, tremor, sweating, confusion), contact emergency medical services immediately. 6. If symptoms persist or worsen, arrange for emergency transfer to a higher level of care (call 911 if necessary).
