We report the use of adrenaline in a 62-year-old woman with carcinoid heart disease who underwent double valve replacement. She was given an intravenous infusion of octreotide throughout the peri-operative period. Following the termination of cardiopulmonary bypass she developed profound hypotension which proved to be refractory to various therapies but responded to adrenaline. Adrenaline is said to be contraindicated in carcinoid syndrome, but we would suggest the consideration of its use in such cases where the hypotension may result from myocardial depression rather than from a carcinoid crisis.

The safety profile of the selective serotonin reuptake inhibitor, fluvoxamine, has been assessed in clinical and post-marketing studies. Post-marketing surveillance provides the opportunity to assess a drug's safety in every day clinical conditions in a much greater patient population than in clinical trials and therefore serves as a useful tool to detect signals for adverse effects with an incidence of less than 1 : 10,000. The safety profile of fluvoxamine was evaluated based on data from 17 years of global post-marketing surveillance in an estimated 28 million patients exposed to fluvoxamine. A total of 6,658 adverse drug reaction reports received from world-wide sources were reviewed and analysed. Post-marketing surveillance data confirmed the favourable safety profile already observed in clinical and post-marketing studies. A remarkably low level of suicidality, switch to mania, and sexual dysfunction was found. Serotonin syndrome appeared to be a very rare complication of fluvoxamine treatment. No signals for drug interactions unknown so far were identified. Withdrawal symptoms were observed in everyday clinical conditions, which were generally mild and resolved spontaneously. However, no cases suggestive for drug dependence have been reported. In conclusion, the data presented underlined that fluvoxamine offers a safe and well-tolerated option in the treatment of depression and obsessive-compulsive disorder.

Depression is a physiological disorder that is medically treated by increasing the bodily amount of one or all of the following neurotransmitters: serotonin, dopamine and norepinephrine. Although there are seven distinct classes of antidepressants, prehospital care professionals should at minimum be able to distinguish the monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and newer antidepressants that are none of these. Monoamine oxidase inhibitors have severe, potentially life-threatening interactions with a variety of medications, including the paramedic drug meperidine, as well as with many common foods. An overdose of tricyclic antidepressants can cause lethal cardiac irregularities. Tricyclics are toxic to children in very small doses. A patient who has overdosed on TCAs may be walking and talking when you first arrive, then quickly deteriorate and die before your eyes. The treatment for TCA overdose is sodium bicarbonate; refer to your medical direction for dosages and indications. A common indication of TCA overdose, secondary to the patient's having access to the drugs, is widening of the QRS complex to greater than 0.12 seconds. Serotonin syndrome is often the result of taking a new generation antidepressant, such as an SSRI, while there is still TCA or MAOI in the bloodstream.

Serotonin syndrome (SS) is a potentially fatal complication of the combined use of agents that enhance serotonin activity. Bupropion inhibits noradrenaline and dopamine reuptake with milder effects on serotonergic activity. Although regarded as a potential causative agent for SS, no cases have been reported in the medical literature. A 62-year-old woman treated with therapeutic dosages of bupropion and sertraline for depression for the previous 3 weeks presented with upper extremity myoclonic jerks, clumsiness, and gait difficulties with fluctuating symptoms of confusion, forgetfulness, and the alternation of agitation and lethargy. Symptoms were interpreted as an aggravation of depression and venlafaxine was added. The clinical picture progressed to alteration of consciousness and dysautonomia. After admission, medications were discontinued and she was started on cyproheptadine and clonazepam with gradual improvement and complete resolution of symptoms. This is a rare report of SS related to the association of bupropion and selective serotonin reuptake inhibitors (SSRIs). It also illustrates the potential for misinterpretation of the earliest manifestations of SS as signs of aggravation of the patient's underlying condition. The role of bupropion in SS is possibly related to its well-established specific inhibition of the cytochrome P450 2D6 pathway, increasing blood levels of SSRIs and tricyclic antidepressants.

Serotonin syndrome is a rare but potentially fatal complication of drugs that have effects on central nervous system serotonin. It is characterized by sudden onset of altered mental status, increased neuromuscular activity and autonomic instability. The author reports a child with suprasellar region tumor who presented with depression and obsessive-compulsive disorder and received a combination of sertaline (selective serotonin reuptake inhibitor) and clomipramine (tricyclic antidepressant). Symptoms of serotonin syndrome occurred within 24 hours after increasing the dose of sertaline. The patient's symptoms resolved rapidly with discontinuation of the offending drugs and supportive care.

Derived from the aerial parts of the plant, St. John's wort generally is used for depression, seasonal affective disorder, and anxiety. Products currently are standardized based on hypericin content, although the hyperforin and bioflavonoid contents are also believed responsible for activity. St. John's wort is metabolized primarily by the liver. Some studies comparing St. John's wort to standard antidepressants suggest that it may be as effective as imipramine or selective serotonin reuptake inhibitors (SSRIs) to treat mild to moderate depression. Results from another clinical trial indicate that the effectiveness of St. John's wort is comparable to paroxetine, an SSRI, in the treatment of moderate to severe depression and is well tolerated. But a meta-analysis shows that data are inconsistent. Studies also show possible efficacy in the management of anxiety and premenstrual syndrome, although additional research is necessary. St. John's wort can interact with many medications owing to induction of cytochrome P-450 3A4 and other mechanisms. Significant interactions include decreased efficacy of antiretrovirals, cyclosporine, tacrolimus, antiepileptics, irinotecan, and other chemotherapeutic agents. Serotonin syndrome may occur when St. John's wort is combined with sympathomimetics, antidepressants, or triptans. Frequently reported adverse events include nausea, headache, constipation, dizziness, confusion, fatigue, and dry mouth. St. John's wort should be used under medical supervision.

Serotonin syndrome, which occurs as a result of enhanced serotonin concentration in the central nervous system, is a well-known adverse effect of serotonin-active medications. The concomitant use of antidepressant drugs associated with lithium as a co-adjuvant seems to increase the risk of this adverse reaction. We report a case of the serotonin syndrome during treatment with lithium and venlafaxine, an antidepressant with a dual selective re-uptake inhibition mechanism, and review the literature for similar cases. A 71-year-old woman developed serotonin syndrome while receiving treatment with moderate doses of lithium and venlafaxine for refractory depression. She had been taking higher doses of venlafaxine during the previous months with no significant secondary effects. Use of the Naranjo adverse drug reaction probability algorithm indicated a probable relationship between serotonin syndrome and treatment with lithium and venlafaxine.

Tramadol hydrochloride is a widely prescribed, centrally acting analgesic marketed in over 90 countries. Before being released in the U.S. in 1995, the drug had been available in Europe for almost two decades. Thus, the pharmacokinetic and pharmacodynamic properties of tramadol have been extensively investigated. However, additional information about the drug continues to be discovered. Tramadol exists as a racemic mixture with the (+)-enantiomer and the (-)-enantiomer, and at least some of their metabolites, having different effects. Tramadol has dual mechanisms of action by which analgesia may be achieved: micro-opioid receptor activation and enhancement of serotonin and norepinephrine transmission. Serotonin syndrome may occur in patients taking combinations of tramadol and other agents that increase serotonin activity. The relative degree of contribution of each mechanism toward pain control is not fully understood. By increasing serotonin and norepinephrine neurotransmission, tramadol may conceivably also exert a degree of antidepressant effect. Therefore, tramadol may be of particular value in patients with chronic pain who also suffer from depression. This drug has been shown to be beneficial in the treatment of a wide range of acute and chronic pain syndromes, including neuropathic pain. While abuse of tramadol may occur, several large studies have demonstrated that the incidence of abuse is rather low, about one case per 100,000 patients.

The serotonin syndrome is a toxic state largely attributable to changes in sensitivity of serotonin receptor system in the brainstem and spinal cord resulting from increased serotonergic activity in central neurologic system, due to use of serotonergic agents either in overdose or in combination. Serotonin syndrome may present with neuromuscular (clonus, myoclonus, tremor, hyperreflexia) and autonomic (fever, mydriasis, tachycardia, tachypnea) symptoms and mental status changes (confusion, agitation) and may result in death in severe cases. The risk for the development of serotonin syndrome is increased with the combined use of agents from different groups such as selective serotonin reuptake inhibitors (SSRIs) and monoamine oxidase inhibitors (MAOIs). The growing use of SSRIs for depression and the introduction of pharmacological agents newly developed for the treatment of various medical disorders increases the risk of drug-drug interactions and toxic states like serotonin syndrome. In the presented case clinical presentation and outcome of the serotonin syndrome which has developed as a consequence of concomitant linezolid use in a young patient who was already on an SSRI antidepressant is discussed. Linezolid is an oxazolidinone antibiotic which has MAOI-like properties. This case is presented to inform psychiatrists especially working in consultation-liaison settings about the risk of drug-drug interactions and possible prevention of these.
