Overdosage of phenylephrine hydrochloride

Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.
10 OVERDOSAGE Overdosage of phenylephrine may cause a rapid rise in blood pressure. It may also cause headache, anxiety, nausea, and vomiting and ventricular arrhythmias. Prompt injection of a rapidly acting alpha-adrenergic blocking agent such as phentolamine has been recommended.

Adverse reactions

Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.
6 ADVERSE REACTIONS The following serious adverse reactions are described below and elsewhere in the labeling: • Cardiac Disease [See Warnings and Precautions (5.2) ]. • Elevation in Blood Pressure [See Warnings and Precautions (5.3) ]. The following adverse reactions have been identified following use of phenylephrine hydrochloride ophthalmic solution. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. • Ocular adverse reactions include eye pain and stinging on instillation, temporary blurred vision, and photophobia ( 6.1 ). • Cardiovascular adverse reactions include increase in blood pressure, syncope, myocardial infarction, tachycardia, arrhythmia and subarachnoid hemorrhage ( 6.2 ). To report SUSPECTED ADVERSE REACTIONS, contact Bausch & Lomb Incorporated at 1-800-553-5340 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Ocular Adverse Reactions Eye pain and stinging on instillation, temporary blurred vision and photophobia, and conjunctival sensitization may occur. 6.2 Systemic Adverse Reactions A marked increase in blood pressure has been reported particularly, but not limited to, low weight premature neonates, infants and hypertensive patients. Cardiovascular reactions which have occurred primarily in hypertensive patients following topical ocular use of phenylephrine hydrochloride ophthalmic solution 10% include marked increase in blood pressure, syncope, myocardial infarction, tachycardia, arrhythmia and subarachnoid hemorrhage [See Warnings and Precautions (5.2 and 5.3) ].

phenylephrine hydrochloride Drug Interactions

Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.
7 DRUG INTERACTIONS • May exaggerate the adrenergic pressor response in patients taking atropine-like drugs ( 7.1 ). • May potentiate the cardiovascular depressant effects of potent inhalation anesthetic agents ( 7.1 ). 7.1 Agents That May Exaggerate Pressor Responses Concomitant use of phenylephrine and atropine may enhance the pressor effects and induce tachycardia in some patients. Phenylephrine may potentiate the cardiovascular depressant effects of some inhalation anesthetic agents.

Clinical pharmacology

Information about the clinical pharmacology and actions of the drug in humans.
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Phenylephrine is an alpha-1 adrenergic receptor agonist used for dilation of the pupil due to its vasoconstrictor and mydriatic action. Phenylephrine possesses predominantly α-adrenergic effects. In the eye, phenylephrine acts locally as a potent vasoconstrictor and mydriatic, by constricting ophthalmic blood vessels and the radial muscle of the iris. 12.2 Pharmacodynamics Maximal mydriasis occurs in 20-90 minutes with recovery after 3 to 8 hours. Systemic absorption of sufficient quantities of phenylephrine may lead to systemic α-adrenergic effects, such as rise in blood pressure which may be accompanied by a reflex atropine-sensitive bradycardia. 12.3 Pharmacokinetics The systemic exposure following topical administration of phenylephrine hydrochloride ophthalmic solution has not been studied. A higher systemic absorption is expected for the 10% solution and when the corneal barrier function has been compromised.

Pharmacodynamics

Information about any biochemical or physiologic pharmacologic effects of the drug or active metabolites related to the drugÕs clinical effect in preventing, diagnosing, mitigating, curing, or treating disease, or those related to adverse effects or toxicity.
12.2 Pharmacodynamics Maximal mydriasis occurs in 20-90 minutes with recovery after 3 to 8 hours. Systemic absorption of sufficient quantities of phenylephrine may lead to systemic α-adrenergic effects, such as rise in blood pressure which may be accompanied by a reflex atropine-sensitive bradycardia.

Pharmacokinetics

Information about the clinically significant pharmacokinetics of a drug or active metabolites, for instance pertinent absorption, distribution, metabolism, and excretion parameters.
12.3 Pharmacokinetics The systemic exposure following topical administration of phenylephrine hydrochloride ophthalmic solution has not been studied. A higher systemic absorption is expected for the 10% solution and when the corneal barrier function has been compromised.
