Hypokalemia, a condition of low blood potassium, affects up to 21% of hospitalized patients. When a patient’s potassium levels drop to a dangerously low level, an intravenous (IV) infusion of potassium chloride is necessary for a rapid and effective restoration of this vital electrolyte.

While not a common side effect at therapeutic doses, a 2017 case study reported a patient who ingested a significant baclofen overdose and developed QTc prolongation, highlighting a specific risk scenario. This potential for cardiac complications primarily emerges in cases of toxicity, so **does baclofen prolong QTC** is not a concern for most standard prescribed uses.

Methadone, a synthetic opioid, is associated with a risk of fatal respiratory depression, particularly during the initial dosing period. Understanding **what are the contraindications for methadone therapy?** is therefore crucial for healthcare providers and patients to ensure safe and effective treatment while mitigating severe side effects and preventing overdose.

Acetylcholinesterase inhibitors like neostigmine are associated with a 1.4-fold increased risk of bradycardia in patients with dementia [1.5.2]. Understanding how does neostigmine cause bradycardia is crucial for its safe clinical use, particularly in anesthesia and neurology.

In the late 1990s, concerns over severe cardiac side effects led the U.S. Food and Drug Administration (FDA) to request the removal of a popular medication, leaving many wondering **what antihistamine was pulled off the market?** The recalls of Seldane and Hismanal fundamentally reshaped the antihistamine landscape.

While commonly regarded as safe for over-the-counter use, reports indicate that famotidine can cause rare but serious side effects, including cardiac arrhythmias. In light of these concerns, a closer look at potential cardiac and neurological risks is warranted to understand **what is the new warning on famotidine**.

Beta-blockers, including metoprolol, are a class of medications commonly prescribed to manage various cardiovascular conditions by reducing the heart's workload. Understanding **how much does 100 mg of metoprolol lower heart rate** is not a simple, universal answer, as individual responses to this medication can vary significantly based on numerous factors.
