Patients with moderate to severe renal or hepatic dysfunction should exercise caution when using this product (see section 5.2).

This product may act as a cerebral stimulant in children and occasionally in adults. Symptoms of overdosage include insomnia, nervousness, hyperpyrexia, tremors and epileptiform convulsions. Large doses of antihistamines may precipitate attacks in epilepsy (see section 4.9).

Diphenhydramine may enhance the sedative effects of central nervous system depressants including alcohol, sedatives and tranquilizers. While taking this product, avoid alcoholic beverages and consult a healthcare professional prior to taking with central nervous system depressants (see section 4.5).

Belarmin can cause drowsiness (see section 4.8).

4.5. Interaction with other medicinal products and other forms of interaction

CNS depressants: This product contains diphenhydramine and therefore may potentiate the effects of alcohol and other depressants including opioid analgesics, anticonvulsants, antidepressants, antihistamines, antiemetics, antipsychotics, anxiolytic sedatives and hypnotics.

Antimuscarinic drugs: As diphenhydramine possesses some anticholinergic activity, the effects of anticholinergics (e.g. some psychotropic drugs and atropine) may be potentiated by this product giving rise to in tachycardia, mouth dryness, gastrointestinal disturbances (e.g. colic), urinary retention and headache.

MAOIs: Not to be used in patients taking MAOIs or within 14 days of stopping treatment as there is a risk of serotonin syndrome.

There are no known interactions associated with menthol.

4.6. Pregnancy and lactation

Although diphenhydramine has been in widespread use for many years without ill consequence, it is known to cross the placenta and has also been detected in breast milk. Menthol is also excreted in breast milk. Belarmin should not be used during pregnancy or lactation unless considered essential by a doctor.

4.7. Effects on ability to drive and use machines

This product may causes drowsiness and patients receiving it should not drive or operate machinery unless it has been shown that their physical and mental capacity remains unaffected.
