BackgroundL-tryptophan is a prescription medication at doses higher than 220 mg per day. At these prescription doses, this medication should be used only under the supervision of a health care professional because of the higher risk of serious side effects and harmful drug interactions. L-tryptophan is prescribed in Canada for use in combination with antidepressants for patients with depressive disorders. Side effects of L-tryptophan include dry mouth, dizziness, nausea, headache, and sexual problems. In rare cases, serotonin syndrome has been reported when L-tryptophan is taken with other drugs that affect the central nervous system. Serotonin syndrome is a potentially life-threatening reaction with symptoms that include high body temperature, agitation, sweating, rapid heart rate and high blood pressure, muscle rigidity, confusion, and seizures.
Lithium is a prescription drug and is approved for treatment of manic episodes of manic-depressive illness. Common lithium side effects include increased thirst and urination, hand tremors and drowsiness. Severe dehydration has been reported. Intoxication can occur, especially when taken with other medications. Symptoms of intoxication can include vomiting, diarrhea, muscle twitches and lethargy. Patients should take lithium only after receiving a diagnosis and prescription from a health care professional. Otherwise, patients risk inappropriate treatment for their condition and harmful drug interactions or side effects.
