deficiency of glucose-galactose malabsorbtion should not take this medicine.
Interaction with other medicinal products and other forms of interaction
Should not be given to patients being treated with monoamine oxidase inhibitors or
within 14 days of stopping such treatment. May enhance the effects of anticholinergic
drugs such as tricyclic antidepressants. May increase the possibility of arrhythmias in
digitalised patients. May enhance the cardiovascular effects of other
sympathomimetic amines (e.g. decongestants).
This medicine should not be taken together with vasodilators, Beta-blockers or
enzyme inducers such as alcohol.
Pregnancy and lactation
The safety of this medicine during pregnancy and lactation has not been established
but in view of a possible association of foetal abnormalities with first trimester
exposure to phenylephrine, the use of the product during pregnancy should be
avoided. In addition, because phenylephrine may reduce placental perfusion, the
product should not be used in patients with a history of pre-eclampsia. In view of the
lack of data on the use of phenylephrine during lactation, this medicine should not be
used during breast feeding.
Effects on ability to drive and use machines
No adverse effects known.
Adverse effects may include tachycardia, cardiac arrhythmias, palpitations,
hypertension, nausea, vomiting, headache and occasionally urinary retention in
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal
product is important. It allows continued monitoring of the benefit/risk
balance of the medicinal product. Healthcare professionals are asked to report
any suspected adverse reactions via the Yellow Card Scheme at
Symptoms of overdosage include irritability, restlessness, palpitations, hypertension,
difficulty in micturition, nausea, vomiting, thirst and convulsions. In severe
overdosage gastric lavage and aspiration should be performed. Symptomatic and
supportive measures should be undertaken, particularly with regard to cardiovascular
and respiratory systems. Convulsions should be controlled with intravenous
diazepam. Chlorpromazine may be used to control marked excitement and
hallucinations. Severe hypertension may need to be treated with an alphaadrenoreceptor blocking drug, such as phentolamine. A beta blocker may be required
to control cardiac arrhythmias.
Phenylephrine is a sympathomimetic agent with mainly direct effects on adrenergic
receptors. It has predominantly alpha adrenergic activity and is without stimulating
effects on the central nervous system. The sympathomimetic effect of phenylephrine
produces vasoconstriction which in turn relieves nasal congestion.
Phenylephrine is readily absorbed after oral administration but is subject to extensive
presystemic metabolism, much of which occurs in the enterocytes. As a consequence,
systemic bioavailability is only about 40%. Following oral administration, peak
plasma concentrations are achieved in 1-2 hours. The mean plasma half life is in the
range 2-3 hours. Penetration into the brain appears to be minimal.
Following absorption, the drug is extensively metabolised in the liver. Both
phenylephrine and its metabolites are excreted in the urine.
The volume of distribution is between 200 and 500 litres, but there are no data on the
extent of plasma protein binding.
Preclinical safety data
There are no preclinical data of relevance to the prescriber which are additional to
that already included in other sections of the SPC.
