Promethazine is a phenothiazine with antihistamine properties that is effective in relieving symptoms of nasal and throat irritation.

This medication is used for symptomatic relief of allergic component respiratory conditions, such as sinusitis, rhinopharyngitis, acute, subacute, and chronic bronchitis.

Interference with analytical tests

This medication may interfere with urine pregnancy tests, both to produce false positives and false negatives.

It should be discontinued at least 72 hours before the start of skin allergy tests as it inhibits the histamine response in the skin and may produce false negatives.

Other medications and Actithiol Mucolítico Antihistamínico

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

• Do not recommend taking carbocisteína with medications that inhibit the cough reflex or with substances that inhibit bronchial secretions (atropinic), as it may cause retention of these bronchial secretions and make it difficult to expel sputum.
• Do not take together with anticholinergic medications, such as imipramine antidepressants, monoamine oxidase inhibitors, antiparkinsonian anticholinergic medications, antispasmodic atropinic medications, disopyramide, or phenothiazine neuroleptics, as they may increase the adverse effects of prometazina (dry mouth, urinary retention, constipation).

• Do not take together with central nervous system depressants (sedatives, hypnotics, anxiolytics, analgesics), as they may potentiate the sedative effect of prometazina.

• Medications that may affect heart rhythm.
