Armed with his prescription from lesson 9.3, Lucas heads to the pharmacy! In this lesson you'll learn the vocabulary for buying medicine, understanding dosage instructions, and asking the pharmacist questions. You'll also master two essential grammar structures: 'devoir + infinitive' (must / have to) and 'il faut + infinitive' (one must / it is necessary to). These are incredibly useful for giving and receiving instructions of all kinds — not just at the pharmacy.
Learning tips
- 'L'officine' is the formal and correct French word for a pharmacy (the dispensing area). You may also hear 'la pharmacie' used for the shop as a whole. Knowing 'officine' will impress a French pharmacist!
- 'Devoir' conjugates like a regular -oir verb: je dois, tu dois, il/elle doit, nous devons, vous devez, ils/elles doivent. It is used with a following infinitive — 'je dois avaler' (I must swallow).
- 'Il faut' is impersonal — it has no subject other than the placeholder 'il' and is always the same form. It applies to everyone: 'il faut avaler avec de l'eau' = 'one must swallow with water / you need to swallow with water'.
- Notice the difference in register: 'vous devez' speaks directly to a person ('you must'), while 'il faut' is general advice ('one must'). Both are very common.
- Dosage instructions in French follow a pattern: number + noun + 'fois par' + time period, e.g. 'deux comprimés trois fois par jour' (two tablets three times a day). You'll hear this often.

Dialog
Lucas arrives at the pharmacy with his prescription. Camille plays the role of the pharmacist. She explains what he has been prescribed — a cough syrup and an ointment — and gives him clear dosage instructions using 'vous devez' and 'il faut'. The dialog also introduces tablets ('comprimés') and the concept of buying medicines without a prescription.

Grammar: Obligation with 'devoir' + infinitive and 'il faut' + infinitive — expressing necessity
| Structure | Exemple | Sens |
|---|---|---|
| je dois + infinitif | Je dois avaler le sirop. | I must swallow the syrup. |
| tu dois + infinitif | Tu dois appliquer la pommade. | You must apply the ointment. |
| il/elle doit + infinitif | Il doit prendre deux comprimés. | He must take two tablets. |
| nous devons + infinitif | Nous devons boire de l'eau. | We must drink water. |
| il faut + infinitif | Il faut avaler avec de l'eau. | One must swallow with water. |
| il faut + infinitif (négatif) | Il ne faut pas oublier le sirop. | One must not forget the syrup. |
This lesson focuses on expressing obligation and necessity — saying what must be done. French has two main ways to do this. The first is 'devoir + infinitive': this verb conjugates for each subject (je dois, tu dois, il/elle doit, nous devons, vous devez, ils/elles doivent) and speaks directly to a person — 'vous devez avaler le sirop' means 'you must swallow the syrup', addressed to you specifically. The second is 'il faut + infinitive': this is impersonal and unchanging — 'il faut' is always the same form, equivalent to 'one must', 'you need to', or 'it is necessary to'. 'Il faut avaler avec de l'eau' applies to everyone. Both structures are negated differently: 'devoir' adds 'ne...pas' around the verb itself ('je ne dois pas oublier'), while 'il faut' adds 'ne...pas' around 'faut' ('il ne faut pas oublier'). The negative form 'il ne faut pas' is very strong — it means it is forbidden or strongly inadvisable. At the pharmacy, you will hear both structures constantly as the pharmacist gives instructions.
