Benzydamine use is not advisable in patient with hypersensitivity to salicylic acid or other NSAIDs.
Bronchospasm may be precipitated in patients suffering from or with a previous history of bronchial asthma. Caution should be exercised in these patients.
In a minority of patients, buccal/pharyngeal ulceration may be caused by serious disease processes. Patients whose symptoms worsen or do not improve within 3 days, or who appear feverish or have other symptoms, must therefore seek the advice of their doctor or dentist as appropriate.
Difflam contains:
– Aspartame: aspartame is hydrolysed in the gastrointestinal tract when orally ingested. One of the major hydrolysis products is phenylalanine that may be harmful for people with phenylketonuria.
– Isomalt: patients with rare hereditary problems of fructose intolerance should not take this medicine.
4.5 Interaction with other medicinal products and other forms of interaction
No interaction studies have been performed in humans.
4.6 Fertility, Pregnancy and lactation
Pregnancy
There are no or limited amount of data from the use of benzydamine in pregnant women, and animal studies are insufficient with respect to reproductive toxicity (see section 5.3).
Difflam lozenges is not recommended during pregnancy.
Breastfeeding
There is insufficient information on the excretion of benzydamine in human milk.
Difflam lozenges should not be used during breastfeeding.
4.7 Effects on ability to drive and use machines
Difflam has no or negligible influence on the ability to drive and use machine, when it is used at the recommended dose.
4.8 Undesirable effects
Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness
The following rate values have been used: Very common (> 1/10), Common (> 1/100 to <1/10), Uncommon (>1/1,000 to <1/100), Rare (>1/10,000 to <1/1,000) and Very rare (<1/10,000), not known (cannot be estimated from the available data).
| System-Organ Class | Frequency | Undesirable effect |
| Immune system disorders | Not Known | Anaphylactic reaction, Hypersensitivity reaction |
| Respiratory, thoracic, and mediastinal disorders | Very rare | Laryngospasm |
| Gastrointestinal Disorders | Rare Not known | Burning mouth, Dry mouth Hypoaesthesia oral |
| Skin and subcutaneous tissue disorders | Uncommon Very rare | Photosensitivity Angioedema |
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 car in the Google Play or Apple App Store.
4.9 Overdose
Symptoms
No overdosage with the lozenge formulation has been reported. However, very rarely in children excitation, convulsions, sweating, ataxia, tremor and vomiting have been reported after the oral administration of benzydamine dosages about 100 times higher than those of the lozenge.
Management
In the event of acute overdosage only symptomatic treatment is possible; the stomach should be emptied by inducing vomiting or by gastric lavage, and the patient carefully observed and given supportive treatment. Adequate hydration must be maintained.
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: other throat preparations ATC code: R02AX03.
Clinical efficacy and safety
Clinical studies demonstrate that benzydamine is effective in relieving suffering from localised
irritation processes of the mouth and pharynx. In addition, benzydamine possesses a moderate local anaesthetic effect.
5.2 Pharmacokinetic properties
Absorption
The absorption through the mucosa of the mouth and pharynx was demonstrated by the presence of measurable quantities of benzydamine in the human plasma.
Distribution
About 2 hours after the 3 mg lozenge administration, benzydamine peak plasma values of 37.8 ng/ml with an AUC of 367 ng/ml*h were observed. However, these levels are not sufficient to produce pharmacological systemic effects.
When locally applied benzydamine has been shown to accumulate in inflamed tissues where it reaches effective concentrations because of its capacity to penetrate the epithelial lining
Biotransformation and elimination
The excretion occurs mainly in the urine and mostly in the form of inactive metabolites or conjugation products.
