نشرة الدوا بتقول: رج شراب الكحة.

It is mainly Egyptian Arabic.

Some clues are:

• الدوا instead of the more formal الدواء
• بتقول with the Egyptian present-tense prefix بـ
• the everyday phrasing overall

A speaker of Modern Standard Arabic would understand it, but it sounds colloquial and Egyptian rather than formal.

نشرة الدوا means the medicine leaflet, package insert, or instruction sheet that comes with a medicine.

A few notes:

• نشرة can mean a leaflet, bulletin, or circular in general.
• With الدوا, it specifically refers to the paper with medical instructions.

So this is not about news; it is about the written instructions that come with the medicine.

الدوا is the Egyptian colloquial form of الدواء, meaning the medicine.

So:

• الدواء = Modern Standard Arabic / more formal
• الدوا = Egyptian everyday speech

This kind of shortening is very common in Egyptian Arabic.

بتقول means it says in Egyptian Arabic.

Why this form?

• The بـ prefix marks the normal present tense in Egyptian.
• The subject is نشرة, which is grammatically feminine singular.
• Because the subject is feminine singular, the verb is also feminine singular: بتقول.

So نشرة الدوا بتقول literally means the medicine leaflet says.

Even though a leaflet is not a person, Arabic still gives it a grammatical gender, and نشرة is feminine.

A natural Egyptian-style pronunciation would be:

nishrit id-dawa bitʔūl: rogg sharāb il-kaḥḥa

Helpful pronunciation notes:

• ج in Egyptian is usually a hard g sound.
• ق in بتقول is usually pronounced as a glottal stop ʔ.
• ال in الدوا is heard as id- here because it assimilates to د.
• رج is pronounced like rogg; the last consonant is doubled.

It is the imperative Shake!

The verb is رجّ in Egyptian Arabic, meaning to shake.

In more careful spelling, you would usually see the shadda:

• رجّ

In casual writing, people often leave out short vowels and sometimes even the shadda, so رج is understood from context.

So here it should be read as رجّ = shake!

Because شراب الكحة is an iḍāfa construction, often called a genitive construction.

Literally, it is something like:

• syrup of the cough

But naturally it means:

• the cough syrup

In this structure:

• the first noun usually does not take ال
• the second noun can be definite
• if the second noun is definite, the whole phrase becomes definite

So شراب الكحة means the cough syrup, even though شراب itself does not have ال.

Yes, the basic meaning of شراب is something like a drink or something to be drunk. But in medical contexts, it very often means syrup or liquid medicine taken by mouth.

So here:

• شراب does not mean an ordinary beverage
• it means syrup
• شراب الكحة = cough syrup

Because كحة is the common everyday Egyptian word for cough.

Compare:

• الكحة = everyday Egyptian
• السعال = more formal / Standard Arabic

So this sentence uses the more natural spoken Egyptian word. That is another sign that the sentence is in colloquial Egyptian rather than formal written Arabic.

In normal usage, it means shake the cough syrup bottle/container before using it.

Arabic often leaves the bottle unstated because it is obvious from context. English does something similar sometimes.

If you wanted to say it more explicitly, you could say:

• رجّ ازازة شراب الكحة

That would mean:

• Shake the bottle of cough syrup
