Dyspnea (breathlessness)
Typically controlled with opioids, like morphine, fentanyl or, in the United Kingdom, diamorphineConstipation

Low food intake and opioid use can lead to constipation which can then result in agitation, pain, and delirium. Laxatives and stool softeners are used to prevent constipation. In patients with constipation, the dose of laxatives will be increased to relieve symptoms. Methylnaltrexone is approved to treat constipation due to opioid use.Other symptoms that may occur, and may be mitigated to some extent, include cough, fatigue, fever, and in some cases bleeding. Medication Administration
Subcutaneous injections are one preferred means of delivery when it has become difficult for patients to swallow or to take pills orally, and if repeated medication is needed, a syringe driver (or infusion pump in the US) is often likely to be used, to deliver a steady low dose of medication. In some settings, such as the home or hospice, sublingual routes of administration may be used for most prescriptions and medications.Another means of medication delivery, available for use when the oral route is compromised, is a specialized catheter designed to provide comfortable and discreet administration of ongoing medications via the rectal route. The catheter was developed to make rectal access more practical and provide a way to deliver and retain liquid formulations in the distal rectum so that health practitioners can leverage the established benefits of rectal administration. Its small flexible silicone shaft allows the device to be placed safely and remain comfortably in the rectum for repeated administration of medications or liquids.
A person will typically have these conversations with their doctor and ultimately record their preferences in an advance healthcare directive. An advance healthcare directive is a legal document that either documents a persons decisions about desired treatment or indicates who a person has entrusted to make their care decisions for them. The two main types of advanced directives are a living will and durable power of attorney for healthcare. A living will includes a persons decisions regarding their future care, a majority of which address resuscitation and life support but may also delve into a patients’ preferences regarding hospitalization, pain control, and specific treatments that they may undergo in the future. The living will will typically take effect when a patient is terminally ill with low chances of recovery. A durable power of attorney for healthcare allows a person to appoint another individual to make healthcare decisions for them under a specified set of circumstances. Combined directives, such as the "Five Wishes", that include components of both the living will and durable power of attorney for healthcare, are being increasingly utilized. Advanced care planning often includes preferences for CPR initiation, nutrition (tube feeding), as well as decisions about the use of machines to keep a person breathing, or support their heart or kidneys. Many studies have reported benefits to patients who complete advanced care planning, specifically noting the improved patient and surrogate satisfaction with communication and decreased clinician distress.
