Abstract
Psychiatric drugs have primacy for off-label prescribing. Among those, selective serotonin reuptake inhibitors (SSRIs) are highly versatile and, therefore, widely prescribed. Moreover, they are commonly considered as having a better safety profile compared to other antidepressants. Thus, when it comes to off-label prescribing, SSRIs rank among the top positions. In this review, we present the state of the art of off-label applications of selective serotonin reuptake inhibitors, ranging from migraine prophylaxis to SARS-CoV-2 antiviral properties. Research on SSRIs provided significant evidence in the treatment of premature ejaculation, both with the on-label dapoxetine 30 mg and the off-label paroxetine 20 mg. However, other than a serotoninergic syndrome, serious conditions like increased bleeding rates, hyponatremia, hepatoxicity, and post-SSRIs sexual dysfunctions, are consistently more prominent when using such compounds. These insidious side effects might be frequently underestimated during common clinical practice, especially by nonpsychiatrists. Thus, some points must be addressed when using SSRIs. Among these, a psychiatric evaluation before every administration that falls outside the regulatory agencies-approved guidelines has to be considered mandatory. For these reasons, we aim with the present article to identify the risks of inappropriate uses and to advocate the need to actively boost research encouraging future clinical trials on this topic.

Abstract
PURPOSE OF REVIEW This review describes the pharmacology of each antidepressant class as it applies to migraine prevention, summarizes the evidence base for each medication, and describes relevant side effects and clinical considerations. Use of antidepressants for migraine prevention in clinical practice is also discussed. RECENT FINDINGS Antidepressants are commonly used as migraine preventives. Amitriptyline has the best evidence for use in migraine prevention. Nortriptyline is an alternative in patients who may not tolerate amitriptyline. The sedating effect of TCAs can be beneficial for patients with comorbid insomnia. SNRIs including venlafaxine and duloxetine also have evidence for efficacy and may be the most effective treatments in patients with comorbid depression and migraine. SSRIs including fluoxetine are not effective for most patients. The side effect burden of antidepressants can be substantial. Patients should be particularly counseled about the possibility of a withdrawal effect from SNRIs. Antidepressants are an important option for preventive treatment of migraine. Further research on the efficacy and tolerability of SNRIs as migraine preventives is needed.

Abstract
Migraine is the most frequent neurological disorder in the adult population worldwide, affecting up to 12% of the general population and more frequent in women (~25%). It has a high impact on our society due to its disabling nature and, therein, reduced quality of life and increased absenteeism from work. Headache is the primary clinical manifestation and it has been associated with ‘a hereditary or predisposed sensitivity of neurovascular reactions to certain stimuli or to cyclic changes in the central nervous system’ (1). Amongst the many neurotransmitters in the brain, the serotonergic (serotonin, 5-HT) system from the brainstem raphe nucleus has been most convincingly implicated in migraine pathophysiology. The documented changes in 5-HT metabolism and in the processing of central 5-HT-mediated responses during and in between migraine attacks have led to the suggestion that migraine is a consequence of a central neurochemical imbalance that involves a low serotonergic disposition. Although the exact cascade of events that link abnormal serotonergic neurotransmission to the manifestation of head pain and the accompanying symptoms has yet to be fully understood, recent evidence suggests that a low 5-HT state facilitates activation of the trigeminovascular nociceptive pathway, as induced by cortical spreading depression. In this short review, we present and discuss the original and most recent findings that support a role for altered serotonergic neurotransmission in the manifestation of migraine headache.

Abstract
Migraine and mood depression demonstrate a high clinical relation and share, also with pain, neurobiological mechanisms, particularly neuro-transmettitorial and phlogistic ones. The choice of an antidepressant to treat both depression and migraine is determined by its efficacy, safety, and tolerability. Antidepressants share comparable effectiveness for the treatment of depressive disorders, but their efficacy on headache varies widely: Tricyclic antidepressants are more effective than SNRIs and SSRIs, but demonstrate dose-limiting side effects.

Abstract
Migraine and metabolic syndrome are highly prevalent and costly conditions. The two conditions coexist, but it is unclear what relationship may exist between the two processes. Metabolic syndrome involves a number of findings, including insulin resistance, systemic hypertension, obesity, a proinflammatory state, and a prothrombotic state. Only one study addresses migraine in metabolic syndrome, finding significant differences in the presentation of metabolic syndrome in migraineurs. However, controversy exists regarding the contribution of each individual risk factor to migraine pathogenesis and prevalence. It is unclear what treatment implications, if any, exist as a result of the concomitant diagnosis of migraine and metabolic syndrome. The cornerstone of migraine and metabolic syndrome treatments is prevention, relying heavily on diet modification, sleep hygiene, medication use, and exercise.

Abstract
Objective Our study was conducted to describe prescription refill patterns among patients newly treated with triptans. Background Although triptans are efficacious in treating migraine headache, the persistency of triptan use among newly initiated users has not been well described. Methods From a US pharmacy claims database, we identified patients receiving new triptan monotherapy prescriptions from 2001 to 2005. Prescription refill information was gathered for two years for each patient. Persistency was defined as sustained refills of the index triptan prescription, regardless of duration between refills. Results Of 40,892 patients receiving a new triptan prescription, 53.8% (N=22031) did not persistently refill their index triptan. Of these, 25.5% discontinued prescription migraine therapy, 7.4% switched to a different triptan, and 67.1% switched to a non-triptan migraine medication at the time of their first refill. Only 46.2% of patients received at least one persistent refill. Conclusions Migraine patients were more likely to discontinue their triptan after their index prescription than at any other time in their prescription refill history. The majority of patients did not persistently refill triptans, but filled prescriptions for non-specific migraine therapies such as opioids and non-steroidal anti-inflammatory drugs. Reasons for triptan discontinuation warrant further investigation.

Abstract
Migraine is common, underdiagnosed, and frequently inadequately treated in the general population. Nausea and vomiting are common reasons for patients to be referred for symptom control. Nausea can be the most prominent feature of migraine; the International Classification of Headache Disorders (ICHD) recognizes cyclical vomiting syndrome as a migraine variant in children, and there is increasing evidence for a similar entity in adults. We present three patients with troublesome nausea uncontrolled by conventional antiemetic therapy. On questioning, all three had other symptoms suggestive of migraine, and two had a family history. Their symptoms settled with the use of various antimigraine therapies. Amitriptyline appears to be particularly useful. A therapeutic trial of prophylaxis may be indicated for patients whose nausea and vomiting may be attributed to migraine.

Abstract
Headache and migraine are common symptoms of the menopause, often associated with irregular periods, hot flashes, and night sweats. Perimenopausal women should routinely be asked about headache and migraine, so that they can be offered appropriate advice. If attacks are infrequent, it may be sufficient to optimize acute treatment strategies. Lifestyle changes, alone or combined with a nonprescription treatment such as isoflavones, may be considered, although evidence of efficacy is limited. In women with migraine and more severe menopause symptoms, continuous hormone replacement therapy should be considered, using a nonoral route and the lowest dose effective in controlling symptoms. For women who have contraindications to estrogen therapy or do not wish to use it, compounds that inhibit serotonin reuptake, such as venlafaxine, fluoxetine, and paroxetine, have all shown efficacy for the control of hot flashes and prevention of migraine. Gabapentin is another nonhormonal option that has clinical trial evidence of effectiveness in treating hot flashes and reducing the frequency and severity of migraine attacks. Although clonidine is licensed in several countries for migraine prophylaxis and treatment of vasomotor symptoms, any benefit from treatment is often offset by adverse events. There is evidence that hysterectomy can increase the frequency of migraine and menopause symptoms, with added morbidity and risk of mortality. Therapy should regularly be evaluated to assess its ongoing need, as hormonal triggers are self-limiting and abate after menopause.

Abstract
Selective seritonin reuptake inhibitors (SSRIs) are widely used antidepressants that are often safer than alternatives, but may produce a variety of cutaneous reactions including spontaneous bruising, pruritus, urticaria, angioedema, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, erythema nodosum, alopecia, hypertrichosis, leukocytoclastic vasculitis, and an acneiform eruption. We review this category of medications and its side effects. Many cutaneous alterations seen in association with SSRIs can be serious, some even life threatening. Because there appears to be cross-reactions between SSRIs, even though they have different chemical structures, it is advisable to use another family of antidepressants if an SSRI is linked with a serious skin eruption.
