Options for thick secretions or dry mouth include
· - reviewing all current medications including those used for sialorrhoea;
· - rehydration;
· - use of humidifiers or nebulisers.
Several artificial saliva products are available in spray and gel format to help ease dry mouth, but some contain sorbitol which may have a laxative effect with excess use.1,17
Fluid intake can be increased with high-water content foods such as jelly, frozen mousses or ice lollies if the person can swallow safely. Proteolytic enzymes in pineapple (bromelain) or papaya (papain) juice drunk before or with a meal can help break down mucus proteins. The enzymes are also available as tablets.17
Reducing dairy products might help, but may affect calorie and nutrient intake. Sucking on sugar-free lozenges may stimulate saliva production but are a choking risk.17
Carbocisteine or acetylcisteine can be taken (via a feeding tube if in liquid form) and normal saline used in nebulisers.
Other suggestion include oral beta-blockers (eg propranolol, metoprolol, or atenolol), although evidence for the impact on secretions is limited and they come with side effects such as hypotension and bradycardia, and guaifenesin cough mixtures.1,3,17
