For the relief of unproductive coughs.
4.2 Posology and method of administration
Adults: 5 ml (one medicine measure) two to three times a day.
Children 5 u2013 12 years: 2,5 ml (half a medicine measure) two to three times a day.
Do not exceed the recommended dose.
4.3 Contraindications
Pholtex Forte should not be given to patients with or at risk of developing respiratory failure as the sedative properties of pholcodine may exacerbate the condition.
Patients with chronic bronchitis, COPD, bronchiolitis or bronchiectasis due to sputum retention.
Patients taking monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping such treatment (see 4.5).
Patients with hypersensitivity or idiosyncratic response to pholcodine or to any of the excipients.
Patients with liver disease since pholcodine is metabolised in the liver and the drug may accumulate.
Children under two years of age.
Pregnancy and lactation. Refer to 4.6.
4.4 Special warnings and precautions for use
Pholcodine should be used with caution in patients who have decreased respiratory reserve.
Pholcodine depresses the respiratory centre to some extent and should be used with caution in asthmatics.
Since pholcodine is metabolised in the liver, its action may be prolonged in hepatic insufficiency.
The dosage and frequency of administration may need to be reduced in patients with impaired liver function.
Use of pholcodine with alcohol or other central nervous system (CNS) depressants may increase the effects on the CNS and cause toxicity in relatively smaller doses.
Severe cutaneous adverse reactions (SCARs) including acute generalized exanthematous pustulosis (AGEP), which can be life-threatening or fatal, have been reported in patients treated with pholcodine, most likely in the first week. Patients should be advised of the signs and symptoms and monitored closely for skin reactions. If signs and symptoms suggestive of these reactions appear, this medicine should be withdrawn immediately.
Contains sorbitol which may have an effect on the glycaemic control of patients with diabetes mellitus.
Medicines containing sorbitol may have a laxative effect. Patients with the rare hereditary condition of sorbitol intolerance should not take Pholtex Forte.
4.5 Interaction with other medicines and other forms of interaction
The reduction in blood pressure caused by antihypertensives may accentuate the hypotensive effects of pholcodine. Diuretics may have a similar effect.
The sedative effects of central nervous system depressants may be increased by alcohol, barbiturates, hypnotics, narcotic analgesics, sedatives and tranquillisers (phenothiazines and tricyclic antidepressants).
Hypertensive crisis may be caused by concurrent use of pholcodine with monoamine u2013 oxidase inhibitors therefore not to be used in patients taking MAOIs or within 14 days of stopping treatment.
Interaction with neuromuscular blocking agents (anaphylaxis) has been reported.
