Patients diagnosed with Alzheimer’s disease, regardless of the duration of the disease, often need to receive medication, which is generally given orally. The following points should be noted when taking medication for dementia patients at home: 1. Elderly people with dementia often forget to take their medication, take the wrong medication, or forget that they have already taken the medication and overdosed, so someone must accompany them when they take their medication and help them to take all the medication so that they do not forget or take the wrong medication. 2. For dementia patients with depression, hallucinations and suicidal tendencies, family members must manage the medication well and put it in a place where the patient cannot reach or find it. 3. Elderly people with dementia often do not admit that they are sick, or often think that the medicine given by family members is poison because of hallucinations and paranoia, so they often refuse to take the medicine. This requires family members to be patient and persuasive, explaining to the patient that the medicine can be crushed and mixed with rice to eat. For patients who refuse to take the medicine, they must watch the patient take the medicine and have the patient open their mouth to see if they swallow it to prevent the patient from spitting it out after being left unattended. 4. Patients with dementia often cannot tell their discomfort after taking medication, so family members should carefully observe what adverse reactions the patient has and adjust the medication regimen in a timely manner. 5, bedridden patients, patients with swallowing difficulties should not swallow the tablets, it is best to crush and dissolve in water to take. Comatose patients should be put under the nasal feeding tube, the drug should be injected by the gastric tube.
