Some individuals may display sympathomimetic amine effects such as tachycardia, palpitations, headache, dizziness, or nausea. Sympathomimetics have been associated with certain untoward reactions including fear, anxiety, nervousness, restlessness, tremor, weakness, pallor, respiratory difficulty, dysuria, insomnia, hallucinations, convulsions, CNS depression, arrhythmias, and cardiovascular collapse with hypotension.

It does this by vasoconstriction, which results in reduction of tissue hyperemia, edema, nasal congestion, and an increase in nasal airway patency. In the usual dose it has minimal vasopressor effects. Pseudoephedrine HCl is rapidly and almost completely absorbed from the gastrointestinal tract. It has a plasma half-life of 6 to 8 hours. Alkaline urine is associated with slower elimination of the drug. The drug is distributed to the body tissues and fluids, including the central nervous system (CNS). Approximately 50% to 75% of the administered dose is excreted unchanged in the urine; the remainder is apparently metabolized in the liver to inactive compounds by N-demethylation, parahydroxylation, and oxidative deamination. Methscopolamine nitrate is a quaternary ammonium derivative of the anticholinergic scopolamine which possesses the peripheral actions of the belladonna alkaloids, but does not exhibit the central actions because of its lack of ability to cross the blood-brain barrier. Its antimuscarinic effect causes inhibition of salivary secretions, reduction in volume and total acid content of gastric secretion, and inhibition of gastrointestinal motility. It is poorly and unreliably absorbed. Drug effects appear in about one hour and persist for about 4 to 6 hours. It is excreted primarily in the urine and bile, or as unabsorbed drug in feces."],"contraindications":["CONTRAINDICATIONS This product is contraindicated in patients with hypersensitivity to pseudoephedrine HCL and methscopolamine nitrate.

Patients may increase the amount of drug and frequency of use, producing toxicity and perpetuating the rebound congestion. Excessive use may cause systemic effects which are more likely in the elderly. Habituation and toxic psychosis have followed long-term high-dose therapy."],"drug_interactions":["Drug Interactions Do not prescribe AlleRx™-D for use in patients that are now taking prescription MAOIs (certain drugs for depression, psychiatric or emotional conditions, or Parkinson’s disease), or for 14 days after stopping MAOI drug therapy. Beta-adrenergic blockers and MAOIs may potentiate the pressor effect of pseudoephedrine HCl. Concurrent use of digitalis glycosides may increase the possibility of cardiac arrhythmias. Sympathomimetics may reduce the hypotensive effects of guanethidine, mecamylamine, methyldopa, reserpine and veratrum alkaloids. Concurrent use of pseudoephedrine HCl with other sympathomimetic amines may increase pressor or cardiovascular effects of either medication. The use of pseudoephedrine HCl may result in additive CNS depressant effects when coadministered with alcohol, antihistamines, psychotropics, or other drugs which produce CNS depression.
