الحساسية ممكن تحصل مع المضاد الحيوي.

In Arabic, especially in general medical statements, الـ can be used more broadly than English the.

So الحساسية here does not necessarily mean one specific allergy already mentioned. It can mean something like:

• allergic reaction
• allergy
• the allergy reaction / allergy in general

This is very natural in Arabic. You could also hear حساسية without الـ in some contexts, but الحساسية ممكن تحصل... sounds normal and idiomatic.

Because الحساسية is grammatically feminine, and the verb agrees with it.

• الحساسية = feminine noun
• تحصل = it happens / occurs for a feminine subject

If the subject were masculine, you would usually get يحصل instead.

So:

• الحساسية ممكن تحصل = an allergic reaction can happen
• If the noun were masculine, the verb would usually be masculine too.

ممكن means possible, can, or may / might, depending on context.

In this sentence, it gives the idea of possibility:

• الحساسية ممكن تحصل = An allergic reaction can happen
• or Allergy may occur

In Egyptian Arabic, ممكن is extremely common for expressing possibility. It is often used instead of a more formal structure.

Arabic often does not use a present-tense verb equivalent to English is / are.

So a sentence like:

• الحساسية ممكن تحصل

literally looks something like:

• the allergy possible happen

But naturally it means:

• An allergic reaction can happen
• It is possible for an allergic reaction to occur

This is normal Arabic sentence structure.

Here تحصل means happen, occur, or take place.

In Egyptian Arabic, حصل is a very common verb for:

• to happen
• to occur
• sometimes to get/obtain in other contexts

In this medical sentence, the meaning is clearly occur:

• الحساسية ممكن تحصل = an allergic reaction can occur

Yes, مع literally means with, but in this kind of medical sentence it often has a broader meaning like:

• with
• when using
• from
• in connection with

So مع المضاد الحيوي means something like:

• with the antibiotic
• when taking the antibiotic
• from the antibiotic

English would often prefer with or from, but Arabic commonly uses مع in this type of context.

Yes, المضاد الحيوي is a standard and correct term for antibiotic. It is understood in Egypt.

But in everyday Egyptian speech, many people also say:

• أنتيبايوتيك = antibiotic (borrowed from English)

So both are possible:

• المضاد الحيوي = more standard / medical / Arabic-based
• أنتيبايوتيك = very common in casual speech

Because حيوي is an adjective describing مضاد in the expression مضاد حيوي.

Arabic adjectives agree with the noun they describe in things like:

• gender
• number
• definiteness

Here:

• مضاد is masculine singular
• so the adjective is حيوي (masculine singular)
• because the phrase is definite, both words take الـ:
  • المضاد الحيوي

So the full phrase means the antibiotic.

It sits somewhere in between, but it works fine in Egyptian Arabic.

Why?

• ممكن is very common in Egyptian Arabic.
• تحصل is also very natural.
• المضاد الحيوي sounds a bit more standard/medical.

So the whole sentence is perfectly understandable and natural, especially in a medical context, but it has a slightly formal or educated feel because of المضاد الحيوي.

A very conversational Egyptian version might be something like:

• ممكن يحصل حساسية مع الأنتيبايوتيك
• or ممكن تيجي حساسية من الأنتيبايوتيك

A common Egyptian-style pronunciation would be roughly:

il-ḥasāsiyya mumkin tiḥṣal maʿ il-miḍādd il-ḥayawi

A few notes:

• الـ is usually pronounced il- in Egyptian Arabic.
• تحصل is often heard as tiḥṣal.
• مع is maʿ.
• المضاد الحيوي may sound a bit careful or formal because it is a medical term.

You do not need perfect transliteration, but the general rhythm is:

il-ḥasāsiyya mumkin tiḥṣal maʿ il-miḍādd il-ḥayawi

Yes. In everyday Egyptian Arabic, تيجي can be used in a natural way for things like symptoms or reactions.

For example:

• ممكن تيجي حساسية مع المضاد الحيوي
• ممكن تيجي حساسية من المضاد الحيوي

This sounds a bit more conversational.

Very roughly:

• تحصل = occur / happen
• تيجي = come / develop / happen

Both can work, but تحصل sounds a bit more neutral or formal here.

Yes, Arabic has some flexibility in word order.

The original sentence:

• الحساسية ممكن تحصل مع المضاد الحيوي

is natural.

But you could also hear:

• ممكن تحصل حساسية مع المضاد الحيوي
• حساسية ممكن تحصل مع المضاد الحيوي

These versions shift the emphasis slightly:

• starting with الحساسية puts focus on the allergic reaction
• starting with ممكن puts focus on the possibility

All are understandable, though the exact choice depends on style and context.

Yes, you might hear both, but the nuance changes slightly.

• الحساسية ممكن تحصل مع المضاد الحيوي
  sounds like a general statement about allergic reactions / allergy
• ممكن تحصل حساسية مع المضاد الحيوي
  sounds very natural too, often like an allergic reaction can happen

In everyday speech, the version without الـ in حساسية is also very common. The given sentence is still completely normal.
