• Hypertension: Seen in anticholinergic toxicity due to decreased parasympathetic tone and possible unopposed sympathetic stimulation. The body's inability to relax vascular tone may contribute to elevated blood pressure.
• Urinary Retention: A classic feature of anticholinergic toxicity. Inhibition of muscarinic receptors leads to impaired detrusor muscle contraction, making urination difficult or impossible.
• Hyperthermia: Results from inhibited sweating (anhidrosis), which is a hallmark of anticholinergic toxicity. Without the ability to cool through evaporation, body temperature rises dangerously.
• Diaphoresis: Excessive sweating is mediated by muscarinic receptor activation in cholinergic toxicity. It's often part of the SLUDGE symptoms seen in organophosphate poisoning or cholinesterase inhibitor overdose.
• Bronchoconstriction: Caused by overstimulation of muscarinic receptors in the airways, leading to narrowed bronchi and increased respiratory secretions — a dangerous feature of cholinergic excess.
• Salivation: Prominent in cholinergic toxicity due to unopposed parasympathetic activation. It may occur along with lacrimation, bradycardia, and other signs of excessive cholinergic stimulation.

A. Triptans should be administered only after other pain medications have been tried: Triptans are first-line agents for moderate to severe migraines and do not require prior use of other analgesics. Delaying their use can reduce effectiveness and prolong the migraine episode.
B. Triptans should be administered at the onset of aura symptoms: Triptans are not recommended during the aura phase, especially for patients with migraines that involve motor or sensory auras, due to concerns about vasoconstrictive effects before pain begins. They are intended for use when headache pain starts.
C. Triptans are most effective when taken early in the migraine attack, at the onset of pain: Triptans work by stimulating serotonin receptors, causing cranial vasoconstriction and reducing neurogenic inflammation. They are most effective when taken as soon as the headache phase begins, not during aura or late in the attack.
D. Triptans can be safely administered every hour until pain relief is achieved: Triptans have strict dosing intervals due to their vasoconstrictive properties, and exceeding recommended doses can lead to cardiovascular complications. They should not be taken more frequently than prescribed.
