How do you say "How many times should I take this medicine?" in Japanese?

Quick use

Use このくすりはいちにちになんかいのみますか (kono kusuri wa ichi-nichi ni nankai nomimasu ka) when you need to confirm how often to take a medicine.

This is especially useful when you understood that you have medicine, but did not catch the schedule clearly.

Chunk or pattern

Keep this as a medicine instruction chunk first.

• このくすりは1日になんかいのみますか = How many times a day should I take this medicine?
• そのくすりは1日になんかいのみますか = How many times a day should I take that medicine?

The useful pattern is:

• この / その くすり は / いちにち に / なんかい のみますか

Core words

• くすり: medicine.
• いちにち: one day.
• なんかい: how many times.
• のみます: take or drink. For medicine, it means “take.”

Helper words and endings

• は: marks the medicine you are asking about.
• に: here, it helps mean “per day” or “in one day.”
• ますか: makes the verb into a polite question.

Practical note

Adding 1日に (ichi-nichi ni) makes the question clearer because medicine instructions usually mean “how many times per day,” not total number of times.
