Ο γιατρός είπε να πάρω ένα χάπι τώρα και σιρόπι πριν κοιμηθώ.

Modern Greek normally does not use an infinitive the way English does. Instead, it uses να + a finite verb.

So είπε να πάρω is literally something like:

• he/she said
• that I take / for me to take

In natural English, that becomes the doctor said for me to take or more simply the doctor said to take.

This is a very common Greek pattern:

• μου είπε να φύγω = he told me to leave
• είπε να περιμένουμε = he said for us to wait

Because πάρω is the aorist subjunctive form of παίρνω.

After να, Greek often chooses between:

• an imperfective/present form for ongoing, repeated, or habitual action
• an aorist form for a single, complete action

Here the doctor is talking about a single act: taking a pill now. So Greek uses να πάρω, not να παίρνω.

Compare:

• να πάρω ένα χάπι τώρα = take one pill now, one complete action
• να παίρνω χάπια κάθε μέρα = take pills every day, repeated action

Because the person who will take the medicine is I.

Greek marks the subject on the verb ending, so πάρω means I take / I should take in this kind of structure.

Even though the sentence begins with Ο γιατρός είπε, the doctor is only the one speaking. The action of taking the medicine belongs to the patient, so the verb is in the first person singular:

• είπε να πάρω = the doctor said that I should take
• not είπε να πάρει = the doctor said that he/she should take

Είπε is the aorist past of λέω, meaning say or tell.

So:

• λέει = he/she says
• είπε = he/she said

In this sentence, Ο γιατρός είπε means The doctor said.

It is a very common past-tense form in Greek.

Greek often leaves subject pronouns out because the verb ending already shows who the subject is.

So:

• πάρω already means I take / I should take
• κοιμηθώ already means I sleep / I fall asleep / I go to sleep

Adding εγώ is possible, but it usually adds emphasis or contrast:

• Ο γιατρός είπε να πάρω... = neutral
• Ο γιατρός είπε να πάρω εγώ... = the doctor said I should take it

Because χάπι is a clearly countable noun: one pill, two pills, and so on. So ένα χάπι is the natural way to say one pill.

Σιρόπι can be used more like a substance or medicine type, so Greek often leaves out the article or number when the exact unit is not the focus. Here it means something like:

• a pill now
• and syrup before bed

If you wanted to focus on a specific unit or kind, Greek could also use an article or number in other contexts. But in medical instructions, bare σιρόπι sounds very natural.

Κοιμηθώ is the aorist subjunctive form of κοιμάμαι.

After πριν when talking about something that has not happened yet relative to the main action, Greek commonly uses this kind of form.

So:

• πριν κοιμηθώ = before I sleep / before I go to sleep / before I fall asleep

The aorist form is used because Greek sees this as one whole event: the moment of going to sleep.

After πριν, Greek very often uses the verb directly without να:

• πριν κοιμηθώ
• πριν φύγω
• πριν έρθεις

This is completely normal and very common.

You may sometimes hear πριν να as well, but πριν + subjunctive form without να is the standard pattern learners should definitely know.

Literally, κοιμηθώ is closer to fall asleep / go to sleep than to be sleeping.

But in everyday contexts like medicine instructions, πριν κοιμηθώ is often understood naturally as:

• before I go to sleep
• before bed
• sometimes simply before I sleep

So the exact English wording can vary depending on context, even though the Greek is perfectly natural.

Because Greek often omits a repeated verb when it is easy to understand from context.

So:

• να πάρω ένα χάπι τώρα και σιρόπι πριν κοιμηθώ

really means:

• να πάρω ένα χάπι τώρα και να πάρω σιρόπι πριν κοιμηθώ

But repeating να πάρω would sound unnecessary here. English does the same thing sometimes:

• take a pill now and syrup before bed

The missing verb is understood.

In this sentence, ο makes it specifically a male doctor.

But the noun γιατρός itself can be used for both male and female doctors. The article shows the gender:

• ο γιατρός = the male doctor
• η γιατρός = the female doctor

So the noun stays the same, while the article changes.

The sentence follows a very natural Greek order:

• Ο γιατρός = subject
• είπε = verb
• να πάρω... = what the doctor said
• τώρα and πριν κοιμηθώ = time expressions

Greek word order is fairly flexible, so some parts can move for emphasis. For example, τώρα could appear in a slightly different place. But the version you have is very normal and idiomatic.

The important structure is:

• είπε να + verb
• then the medicine and time details

So even if the order shifts a little, that core pattern stays the same.
