Cough suppressants may cause sputum retention and this may be harmful in patients with chronic bronchitis and bronchiectasis.
This medicine should be used with care in conditions such as closed angle glaucoma, urinary retention, prostatic hypertrophy or pyloroduodenal obstruction. Caution should also be observed in patients with epilepsy and severe cardiovascular disorders.
As pholcodine is a sedative, caution is needed in those patients who have airway disease e.g. asthma, chronic obstructive pulmonary disease (COPD) and ventilatory insufficiency, as respiratory depression may occur. Caution is also needed in patients with kidney disease or a history of drug abuse.

If symptoms persist for longer than 5 days talk to your doctor.

Interaction with neuromuscular blocking agents (anaphylaxis) has been reported.
The reduction in blood pressure caused by antihypertensives may accentuate the hypotensive effects of pholcodine. Diuretics may have the same effect. Pholcodine may enhance the sedative effect of central nervous system depressants including alcohol, barbiturates, hypnotics, narcotic analgesics, sedatives and tranquillisers (phenothiazines and tricyclic antidepressants).
The safety of pholcodine in pregnancy has not been fully established but its use has not revealed any direct evidence of teratogenicity. However, in view of the possible association of foetal abnormalities with first trimester exposure to diphenhydramine, use of the product during pregnancy should be avoided. The safety of this product during lactation has not been established and use during this period should be avoided.
May cause drowsiness. If affected do not drive or operate machinery.

Immune system disorders: hypersensitivity reactions, anaphylaxis.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 www.mhra.gov.uk/yellowcard
Symptoms of overdosage may include nausea, vomiting, drowsiness, restlessness excitement, ataxia, respiratory depression and occasionally convulsions and hyperpyrexia. In cases of severe overdosage, the stomach should be emptied by aspiration and lavage. The patient should be kept quiet to minimise excitation which occurs particularly in children. The specific narcotic antagonist naloxone may be used to reverse any respiratory depression. Convulsions may be controlled with intravenous diazepam. Otherwise treatment should be symptomatic and supportive.
Pholcodine is a cough suppressant with mild sedative but little analgesic action.
Diphenhydramine has antihistamine properties with a pronounced sedative action.
Pholcodine is readily absorbed from the gastrointestinal tract. It can relieve local irritation of the respiratory tract for about 4 to 5 hours.
Peak plasma levels of diphenhydramine hydrochloride occur 2 to 4 hours after administration. Diphenhydramine is about 85 - 98% bound to plasma proteins. The plasma half life ranges from 2.4 to 8 hours.
Diphenhydramine undergoes extensive pre-systemic metabolism which results in 50% metabolism of an oral dose. The major route of elimination is in the urine, largely as metabolites with very little unchanged drug present.
