Introduction

If you have ever experienced dizziness or vertigo or any neck-related problem such as Cervical Spondylosis, loss of cervical lordosis, or even conditions like Benign Paroxysmal Positional Vertigo (BPPV), other inner ear problems

Or even if your dizziness is due to blood pressure fluctuations…

Then there is a high chance that you have taken a medicine named Cinnarizine at some point.

It is commonly available in 25 mg tablets, easily accessible in the market, and widely prescribed by doctors for managing dizziness and vertigo.

You may have seen it under different brand names such as:

• Vertigo
• Vertizac
• Stugeron
• and many others

What exactly is this medicine?

Before we go ahead, let me tell you something

In this section, we will go a little technical to understand the medicine better.
If you just want practical information, you can skip this part — but honestly, understanding this will make everything much clearer.

It is a medicine that has two important actions:

• It works as a calcium channel blocker
• And also as an antihistamine (H1 blocker)

What does that actually mean?

Let’s simplify it.

1. Calcium channel blocking action

Calcium plays an important role in:

• nerve signal transmission
• muscle contraction

It reduces calcium entry into certain cells, which helps to:

• stabilize nerve signals
• reduce excessive stimulation

2. Antihistamine action

It also blocks histamine (H1 receptors), which:

• helps reduce motion sickness
• calms the balance system

What about the brain?

It can cross the blood-brain barrier

This is very important. Because of this:

• it can directly act on the brain’s balance center
• and also affect the inner ear (vestibular system)

Now connect the dots

When you experience dizziness or vertigo, the cause is not always the same.

1. In some conditions, like Benign Paroxysmal Positional Vertigo,
   the inner ear sends abnormal or confusing signals to the brain.
2. In other cases, such as neck-related problems (including Cervical Spondylosis or muscle spasm like loss of cervical lordosis),
   the issue is not directly in the ear — but the neck, muscles, and nerves indirectly disturb balance signals.
3. And in situations like low blood pressure, dehydration, or weakness,
   the brain may temporarily receive reduced blood flow or oxygen, leading to dizziness

So what is common in all of these?

No matter the cause, the final problem is this:

Your brain is receiving unstable or confusing signals about balance.

Where does It help?

It does not directly treat each cause.

Instead, it works at the final level — the brain’s balance processing system:

1. It makes your system less sensitive to imbalance
2. It calms the balance center in the brain
3. It reduces overactive or abnormal signals

Result of which is :

• dizziness reduces
• spinning settles
• you feel stable again

Simple way to remember

It slows down the overactive balance signals and calms your brain.”

Does Cinnarizine treat the problem or just control symptoms?

Now this is something very important to understand.

It mainly controls (or “masks”) the symptoms so that you can go through your day more comfortably.

• It reduces dizziness
• It settles the spinning sensation
• It helps you function better in day-to-day life

But It does NOT treat the underlying cause.

Then what actually treats the root cause?

That depends on the reason behind your dizziness:

• If it is Benign Paroxysmal Positional Vertigo → repositioning exercises (like Epley) are needed
• If it is Cervical Spondylosis or muscle spasm → posture correction & neck exercises are essential
• If it is due to BP fluctuation → dietary changes, hydration, and proper medication are required

So the real treatment is always cause-specific

A small but important point (blood pressure effect)

This medicine is also a calcium channel blocker (CCB).

Because of this:

• it can cause a slight fall in blood pressure

Technically, it could be used in high BP…

But: it is NOT used as a primary treatment for hypertension

Why does it cause sleepiness?

It cause sleepiness because

• crosses the blood-brain barrier
• and works as an H1 antihistamine

That’s why:

• it has a sedative (sleep-inducing) effect

Important advice

Avoid alcohol completely while taking this medicine

Because:

• sedation can increase
• you may feel excessive drowsiness or imbalance

But not everyone feels sleepy

Interestingly:

• some people feel clear drowsiness
• while others feel almost normal

This varies from person to person

Why do doctors usually give it during the day?

You might have noticed that Doctors often prescribe it in the morning or afternoon, not at night.

Reason:

• dizziness affects your day-to-day activities
• like walking, working, turning your head

During the day:

• movement is more
• symptoms are more noticeable

At night:

• you are mostly lying down
• less movement → less dizziness

So the focus is to keep you functional during the day

From my personal experience as a pharmacist, almost every prescription that I have dispensed has been written for daytime use, usually in the afternoon. Only in more severe cases have I seen it prescribed twice daily (BD), otherwise it is most commonly given once daily and that too during the day.

Why does dizziness come back even after taking Cinnarizine?

This is one of the most common questions patients have.

You take the medicine…
You feel better…
And then after a few days or weeks — the dizziness comes back again.

Why does this happen?

The reason is it controls the symptoms, but the root cause remains untreated.

Let’s understand with simple examples

• If your dizziness is due to Benign Paroxysmal Positional Vertigo → you need repositioning exercises
• If it is due to Cervical Spondylosis or muscle strain → you need posture correction and exercises
• If it is due to BP fluctuation → you need proper medical management

if you skip these, symptoms are likely to return.

When should you NOT rely on Cinnarizine?

This medicine is helpful, but not in every situation.

You should not depend on it alone if:

• dizziness is continuous and severe
• symptoms are getting worse
• you don’t know the exact cause

In such cases, proper evaluation is important.

Red flag symptoms

If dizziness is associated with:

• weakness in one side of the body
• difficulty in speaking
• double vision
• severe imbalance or inability to walk

Seek medical help immediately.
These can be signs of serious conditions

How long should you take this medicine?

• Usually prescribed for short-term use
• Duration may vary depending on the condition

Long-term use should only be under medical supervision

Because:

• it may mask symptoms
• and increase risk of side effects

Long-term side effects

Although generally safe for short-term use, prolonged use may lead to:

• excessive drowsiness
• weight gain
• Parkinson-like symptoms (rare but important)

A real-life pattern (very common)

Many patients do this:

Take medicine → feel better → stop everything → symptoms return

This cycle continues.

The missing part is: treating the actual cause

Practical tips to manage dizziness

• Avoid sudden head movements
• Maintain proper posture (especially during mobile/laptop use)
• Stay well hydrated
• Follow exercises if advised
• Do not rely only on medication

Quick comparison

Medicine	Main role
Cinnarizine	Symptom control
Betahistine	Improves inner ear circulation
Dimenhydrinate	Motion sickness relief

From my experience as a pharmacist, many patients rely only on medication for relief.

But those who:

• correct their posture
• follow exercises
• and understand the cause

tend to recover much better and faster.

Final takeaway

Cinnarizine can help you feel better…
but it is not the complete solution.

The real improvement comes when you identify and treat the cause of dizziness.
