l-tryptophan

Tryptophan is available in Canada as a prescription medication to help manage mood disorders, including bipolar disorder and depression. It is typically used alongside other medications to stabilize mood and reduce behavioral extremes by balancing natural substances in the brain, such as serotonin and melatonin. Tryptophan is an amino acid naturally found in protein-rich foods and milk. In the United States, tryptophan is marketed as a dietary supplement and is commonly used to improve mood, promote relaxation, and aid in restful sleep. It is crucial to consult a healthcare professional before combining tryptophan with other medications that affect serotonin levels, such as antidepressants, due to the risk of serious, potentially life-threatening interactions. Continuous monitoring by a doctor is advised. Be aware that some supplements may contain harmful impurities or additives, so it is essential to discuss your choice of brand with a pharmacist. The U.S. FDA has not evaluated this product for safety or effectiveness, so consulting with a healthcare provider for more information is recommended.

Tryptophan Interactions

A product that may interact with this drug is: sodium oxybate. Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Avoid taking MAO inhibitors (isocarboxazid, linezolid, metaxalone, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before and after treatment with this medication. Ask your doctor when to start or stop taking this medication. The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs. Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine). Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
Tryptophan FAQs
Does tryptophan make you sleepy?

Tryptophan is an amino acid that can contribute to sleepiness. It is a precursor to serotonin, a neurotransmitter that can be converted into melatonin, a hormone that regulates sleep. Therefore, consuming tryptophan-rich foods may promote sleepiness in some individuals.

Tryptophan was temporarily banned in the United States in 1989 due to an outbreak of a rare condition called eosinophilia-myalgia syndrome (EMS). This condition was linked to contaminated batches of tryptophan supplements produced by a single manufacturer in Japan. The ban was lifted in 2005 after regulatory measures were put in place to ensure the safety and quality of tryptophan supplements.

Excessive tryptophan in the body can lead to a condition known as eosinophilia-myalgia syndrome (EMS), which is characterized by severe muscle pain, skin changes, and high levels of eosinophils in the blood. Additionally, high levels of tryptophan can increase serotonin production, potentially leading to serotonin syndrome, a serious condition with symptoms such as confusion, rapid heart rate, and high blood pressure. It is important to maintain a balanced intake of tryptophan to avoid these adverse effects.

Tryptophan was temporarily removed from the market in 1989 due to an outbreak of eosinophilia-myalgia syndrome (EMS), a serious condition that affected many individuals. This outbreak was linked to contaminated batches of tryptophan supplements produced by a single manufacturer. Once the source of contamination was identified and addressed, tryptophan was reintroduced to the market under stricter regulations to ensure safety.

Individuals who should avoid tryptophan include those taking medications such as selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), or other antidepressants, as combining these with tryptophan can increase the risk of serotonin syndrome. Additionally, people with liver or kidney disease should be cautious, as tryptophan can exacerbate these conditions. Pregnant or breastfeeding women should consult a healthcare provider before using tryptophan supplements. It's always advisable to consult with a healthcare professional before starting any new supplement, especially if there are existing health concerns or medications involved.
