Abstract
Minoxidil is a drug designed for the treatment of arterial hypotension. Due to its secondary effect of hypertrichosis, it is also used for alopecia treatment. We present a case of a 50-year-old female patient who was orally consuming Minoxidil for medical reasons. She presented with severe hypotension, requiring vasoactive drugs, and evidence of myocardial injury was detected using speckle tracking echocardiography. It is worth noting that the patient did not have any coronary heart disease, and the myocardial injury was found to be associated with Minoxidil consumption. Remarkably, the patient showed signs of reversal 72 h after stopping the drug. To our knowledge, this is the first reported case of subendocardial injury associated with Minoxidil, using speckle tracking echocardiography. In the resolution of the case, it was essential to rule out differential diagnoses, administer vasopressors, and use the speckle tracking echocardiography, which allowed for the objective assessment of myocardial injury and the monitoring of the patient during their hospitalization.

Abstract
CASE DESCRIPTION A 2-year-old sexually intact female mixed-breed dog was evaluated at an emergency hospital approximately 5 hours after ingestion of an unknown amount of over-the-counter topical hair growth promoter containing 5% minoxidil foam. Vomiting and signs of lethargy were reported by the owner, and physical examination revealed tachycardia and hypotension. No treatments were performed, and the dog was transferred to a veterinary referral hospital for management of suspected minoxidil toxicosis. CLINICAL FINDINGS On arrival at the referral hospital, the dog was tachycardic (heart rate, 200 to 220 beats/min) and hypotensive (systolic arterial blood pressure, 70 mm Hg). Electrocardiography revealed a regular, narrow-complex tachycardia with no evidence of ventricular ectopy. TREATMENT AND OUTCOME Hypotension was effectively managed with a constant rate infusion of dopamine hydrochloride (12.5 μg/kg/min [5.7 μg/lb/min], IV). Once normotensive, the dog remained tachycardic and a constant rate infusion of esmolol hydrochloride (40 μg/kg/min [18.2 μg/lb/min], IV) was initiated for heart rate control. A lipid emulsion was administered IV as a potential antidote for the toxic effects of the lipophilic minoxidil, with an initial bolus of 1.5 mL/kg (0.7 mL/lb) given over 15 minutes followed by a continuous rate infusion at 0.25 mL/kg/min (0.11 mL/lb/min) for 60 minutes. While hospitalized, the dog also received maropitant citrate and ondansetron. Resolution of clinical signs was achieved with treatment, and the dog was discharged from the hospital 36 hours after admission. Four days later, the owner reported that the dog had made a full recovery and had returned to its typical behavior and activity level at home. CLINICAL RELEVANCE To the authors' knowledge, this is the first report of successful clinical management of accidental minoxidil toxicosis in a dog.

Abstract
Minoxidil is an antihypertensive direct vasodilator that can cause severe toxicity when sufficiently ingested. We report a case of accidental ingestion of 5 ml topical minoxidil solution 5% presented with chest pain and new-onset ST depressions. After giving IV saline and performing echocardiography/angiography, the patient fully recovered without any pharmacotherapy such as vasopressors and discharged 4 days after admission. The clinical toxicology, treatment, and previous case reports of minoxidil poisoning have been reviewed.

Abstract
Case A 47-year-old man ingested 60 mL of a topical solution (3,000 mg minoxidil) and presented with prolonged hypotension. Treatment with dopamine hydrochloride and noradrenaline provided blood pressure control. Serum unchanged minoxidil concentrations at 4 and 16 h after ingestion were 4,994 and 33.9 ng/mL, respectively. Urine concentrations of unchanged minoxidil, minoxidil-O-glucuronide, and minoxidil-N-O-sulfate at 16 h after ingestion were 360.4, 1,953, and 104.5 ng/mL, respectively. Outcome The serum unchanged minoxidil concentration rapidly decreased over a short interval. However, the patient needed to receive vasopressor support for the first 4 days after being admitted to the hospital. The urine minoxidil-O-glucuronide concentration was higher than the concentrations of unchanged minoxidil and minoxidil-N-O-sulfate. Conclusion Although the serum concentration of unchanged minoxidil rapidly decreased, ingesting large amounts of a topical minoxidil solution can have serious and prolonged cardiovascular effects. Analyzing the minoxidil-O-glucuronide concentration in urine is useful for diagnosing minoxidil poisoning.

Abstract
Minoxidil hair formulation is commonly used for the treatment of male or female androgenic alopecia. This over-the-counter product is wrongly considered safe. The ingestion of a few milliliters by a child can lead to significant intoxication. We report a case of significant intoxication after the ingestion of topical minoxidil (Alopexy; Pierre Fabre Laboratoires, SA, Switzerland). A 7-year-old girl, who accidentally ingested a teaspoon of minoxidil hair solution, presented to the pediatric emergency department for emesis. At admission, she had a blood pressure of 86/56 mm Hg and a pulse of 149 beats per minute. Hypotension lasted 40 hours with the lowest value 24 hours after ingestion (79/33 mm Hg). She presented electrocardiogram changes (sinus tachycardia and flattening T-waves) but normal cardiac enzymes. Infusion of 20 mL/kg of normal saline fluid had no hemodynamic effect. Her blood pressure normalized on day 2. Minoxidil topical solution is an unsafe product for children. This formulation should be strictly kept out of reach of children and manufacturers should enhance child-resistance security of packaging. The over-the-counter availability must be questioned.

Abstract
BACKGROUND Minoxidil (Rogaine®) is a direct vasodilator that can cause significant toxicity when ingested. We report a case of ingestion of topical minoxidil [Rogaine® (Johnson & Johnson Healthcare Products, Division of McNeil-PPC, Inc)] resulting in refractory hypotension that was successfully managed with the oral α (1) agonist midodrine. CASE REPORT A 48-year-old male who ingested an eight ounce bottle of Rogaine® presented to the emergency department. The patient presented with a blood pressure of 57/45 mmHg and a pulse of 84 beats per minute. The patient received IV fluids and multiple vasopressors to maintain an adequate mean arterial pressure. Midodrine, an oral α (1) vasopressor, was added 10 hours post ingestion and was able to maintain an adequate mean arterial pressure. Over the next two days, midodrine was titrated down as his blood pressure returned to baseline. CONCLUSION Midodrine may serve as an additional option to treat toxicant induced hypotension.

Abstract
Accidental intoxications in children are frequent but most of them are without serious consequences. We describe herein the case of a young girl who drank 100 mg of a topical hair lotion with minoxidil. On arrival, she had no symptoms except flush on the face and ears. Four and half hours after ingestion, tachycardia appeared with a pulse above 170 beats per min with hypotension at 76/24 mmHg. The heart rate remained between 170 and 190 beats per min for 12 h and then lowered to between 140 and 160 beats per min. Thirty-six hours after ingestion, the heart beat was at 140 beats per min. Minoxidil is a strong vasodilator used first in the 1970s for severe hypertension. It produces hypotension by direct arteriolar vasodilatation. Only a few cases of minoxidil intoxication have been described in the literature, including only one pediatric case. This young boy had only tachycardia of 160 beats per min for 40 h. Most serious cases have been described in adults. They suffered long-lasting tachycardia, hypotension, and ECG changes. Most patients need a bolus of normal saline fluid and some with hemodynamic problems need vasoactive drugs such as dopamine and/or phenylephrine. All patients need to be under medical supervision for a long time because of the product's very long action.

Abstract
Historically, certain terms used to describe psychopathology have evolved over time due to changing social and political contexts. This paper explores the importance of a clear and consistent language for characterizing suicide-related behaviors with a particular focus on the commonly used label "suicide gesture." The historical and contemporary uses of the term are explored, and clinical, research, and training implications are discussed. Clinicians and researchers are strongly encouraged to consider discontinuing the use of the term suicide gesture in light of its associated dismissive connotations and inconsistent application in clinical practice and research. In lieu of the term suicide gesture, recommendations are made regarding an increased emphasis by clinicians and researchers on more precise descriptions of suicidal behaviors and the functional assessment of suicide-related behaviors.

Abstract
CASE REPORT Minoxidil is a potent arterial vasodilator used in the treatment of hypertension. A side effect, hypertrichosis, has prompted the marketing of a topical preparation, Rogaine, for the treatment of male-pattern baldness. Recently, a 5% solution of minoxidil became available over-the-counter as Rogaine Extra Strength For Men Hair Regrowth Treatment. We describe an oral overdose of minoxidil 3 g as the Rogaine Extra Strength preparation. Toxicity manifested as profound hypotension, requiring vasopressor support, intubation, prolonged tachycardia, and fluid overload with pleural effusions, requiring several days of therapy with furosemide. This is the largest reported ingestion of minoxidil and the first reported overdose of the extra strength 5% solution.
