When it comes to taking medication, there are several synonyms you can use instead of 'dose up'. For instance, 'administer' means to give medicine to someone, while 'deliver' can be another alternative. 'Prescribe' refers to a medical professional advising the patient to take a certain amount and duration of medicine, while 'dispense' means to provide someone with their medication from a pharmacy. Additionally, 'ingest' is another synonym for 'dose up' that refers to swallowing a medication or supplement. It's essential to consult a healthcare provider before taking any medication, and it's better to stick to the prescribed dosage to ensure the body gets the precise amount.
