Risk from concomitant use of sedative medicines such as benzodiazepines or related drugs:
Concomitant use of pholcodine and sedative medicines such as benzodiazepines or related drugs may result in sedation, respiratory depression, coma and death. Because of these risks, concomitant prescribing with these sedative medicines should be reserved for patients for whom alternative treatment options are not possible. If a decision is made to prescribe this medicine concomitantly with sedative medicines, the lowest effective dose should be used, and the duration of treatment should be as short as possible.
The patients should be followed closely for signs and symptoms of respiratory depression and sedation. In this respect, it is strongly recommended to inform patients and their caregivers to be aware of these symptoms (see section 4.5).
Monoamine oxidase inhibitors: Galenphol Strong should not be used within 14 days of treatment.
Interaction with neuromuscular blocking agents (anaphylaxis) has been reported.
The reduction of blood pressure caused by antihypertensives may accentuate the hypotensive effects of pholcodine monohydrate. Diuretics may have the same effect.
Pholcodine monohydrate may enhance the sedative effect of central nervous system depressants including alcohol, barbiturates, hypnotics, narcotic analgesics, sedatives and tranquillisers (phenothiazines and tricyclic antidepressants).
Sedative medicines such as benzodiazepines or related drugs:
The concomitant use of opioids with sedative medicines such as benzodiazepines or related drugs increases the risk of sedation, respiratory depression, coma and death because of additive CNS depressant effect. The dose and duration of concomitant use should be limited (see section 4.4).
No data available on the use of Galenphol Strong in pregnancy or lactation. It should only be used in pregnancy if considered necessary by the physician and should be avoided during the first trimester.
Pholcodine monohydrate has been detected in human milk but in amounts unlikely to affect the suckling infant.
Using the dose recommended, it is not considered to be a hazard, however, the use of pholcodine monohydrate may cause sedation, dizziness and nausea. If affected, driving or operation of machinery would not be advised.
The following side effects may be associated with the use of pholcodine monohydrate:
Occasional drowsiness, dizziness, excitation, confusion, sputum retention, vomiting, gastrointestinal disturbances (nausea and constipation) and skin reactions including rash.
Immune system disorders have been noted including hypersensitivity reactions and 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 or search for MHRA Yellow Card in the Google Play or Apple App Store.
It is thought to be of low toxicity, but the effects in overdosage will be potentiated by simultaneous ingestion of alcohol and psychotropic drugs.
Symptoms of overdose include respiratory depression, restlessness, excitement, ataxia, nausea and drowsiness. Treatment should be symptomatic to maintain vital functions. Respiratory distress should be treated by supportive means. Airways protective gastric lavage may be used.
In severe cases a narcotic antagonist such as naloxone may be considered. Naloxone has been used successfully to reverse central or peripheral opioid effects in children (0.01mg/kg body weight). Other treatment option is activated charcoal (1g/kg body weight) if more than 4mg/kg has been ingested within 1 hour, provided the airway can be protected.
