Atarax
In brief
- Atarax (hydroxyzine) is a prescription-only medicine (POM) in the UK; the original brand has been phased out and generic hydroxyzine is supplied instead.
- Atarax is used for allergic itching, anxiety and short-term sedation. It works as a first-generation antihistamine with sedative, anxiolytic and antipruritic effects by blocking H1 histamine receptors and reducing central nervous system activity.
- The usual dose for adults is 25 mg 3–4 times daily for itching, or 50–100 mg per day divided for anxiety. Doses should be adjusted by a doctor for children, older adults, and people with kidney or liver problems.
- Atarax is usually taken as tablets or oral solution. Tablet strengths commonly include 10 mg and 25 mg; the solution is commonly 10 mg/5 ml.
- Atarax usually starts working within 15–60 minutes, depending on the form taken and the reason for use.
- The effect generally lasts around 4–6 hours, although sedation may feel longer in some people.
- Alcohol should be avoided, as it can significantly increase drowsiness, dizziness and impaired judgement when taken with Atarax.
- The most common side effects are drowsiness, dry mouth, dizziness, headache, blurred vision, fatigue, constipation and nausea.

What Atarax is used for
Hydroxyzine is used for stubborn itching, urticaria, eczema-related pruritus, short-term anxiety and sedation. It should be used under medical guidance and is not an over-the-counter antihistamine or a casual sleep aid.
Hydroxyzine (Atarax): what it is and how it is classified
- International name
- Hydroxyzine.
- Drug class
- A sedative antihistamine with anxiolytic activity.
- ATC classification
- N05BB01 for anxiolytic use and R06AE03 for systemic antihistaminic use.
Hydroxyzine is best thought of as a medicine that sits between allergy treatment and short-term calming treatment.
It is a sedative antihistamine, and in practice it can work both as an antipruritic prescription option and as an anxiolytic.
That dual role is why it is often mentioned by dermatologists and psychiatrists in the same breath, even though patients usually come in with just one complaint.
When someone asks about hydroxyzine tablets, the real issue is usually whether it is being used for itching, tension, or pre-operative sedation.
Definition and active ingredient
The active ingredient is hydroxyzine, not the brand name itself.
That matters because Atarax packaging varies by market, while the medicine’s core pharmacology stays the same.
For UK patients, the practical focus is usually the hydrochloride tablet formulation supplied by a pharmacy on prescription.
Classification in practice
In everyday pharmacy work, hydroxyzine has two main use patterns.
It is prescribed for allergy and itching symptoms, and it is also used for anxiety relief when a short-term sedating effect is helpful.
That is why patients often compare it with other antihistamines and with short-term anxiolytics.
Brand names and packaging
In the UK, Atarax is effectively a phased-out name, while hydroxyzine hydrochloride tablets are the practical pharmacy reality.
Tablets are commonly seen in 10 mg and 25 mg strengths. Oral solution or syrup is usually 10 mg/5 ml and may come with a dosing cup.
Blisters and bottles are the usual packaging formats.
Prescription status and NHS rules
Hydroxyzine is prescription only in the UK and should be treated that way.
For NHS patients, the usual route is GP or specialist prescribing, followed by dispensing in a community pharmacy or via an electronic prescription.
Available forms and strengths: tablets and syrup
| Form | Strengths | Typical packaging | Best use |
|---|---|---|---|
| Tablets | 10 mg, 25 mg | Blister packs | Most adults |
| Oral solution / syrup | 10 mg/5 ml | Bottle with dosing cup | Children or precise dose adjustment |
Most adults are supplied with tablets, depending on the indication and the prescriber’s plan.
Syrup is more useful when the dose has to be adjusted carefully, especially in children.
Which form suits which patient
Tablets are usually the default for adults who can swallow them reliably.
Hydroxyzine syrup for children is often preferred when an exact mg/kg dose is needed and a smaller volume gives better control.
Common uses: itching, urticaria, eczema-related pruritus, and anxiety
The answer is that hydroxyzine has a genuine place in both symptom areas.
It is used for itching-related problems such as urticaria and eczema-associated pruritus, and it can also be chosen for short-term anxiety or sedation.
- Skin-related itch: useful when the itch is persistent or distressing.
- Anxiety relief: used as a sedative antihistamine with anxiolytic action.
- Short-term sedation: sometimes used before procedures or alongside other care.
Dermatology patients often want a medicine that settles the itch quickly enough to sleep, while anxiety patients may want something that takes the edge off without the same profile as a benzodiazepine.
Hydroxyzine can fit both stories, but only when a prescriber has decided it is appropriate.
Allergy and skin-related itching
Its antipruritic effect is one of the main reasons it remains in routine use.
When itching is severe enough to disturb sleep, hydroxyzine may be chosen because the sedating effect can also help the patient settle down at night.
Anxiety and short-term sedation
For anxiety, it is often used short term and reviewed regularly rather than left on indefinitely.
It may also be used as pre-operative sedation or as an adjunct when a calming effect is wanted before a procedure.
How Atarax is dosed in adults and children
| Indication | Adult dosage | Paediatric dosage |
|---|---|---|
| Allergic pruritus | 25 mg, 3 to 4 times daily, max 100 to 150 mg daily | 0.5 to 1 mg/kg/dose, 3 to 4 times daily |
| Anxiety or tension | 50 to 100 mg daily divided, max 100 mg | Typically 1 mg/kg or as directed by the doctor |
| Sedation | 50 to 100 mg as a single dose | 0.6 mg/kg as a single dose or as directed |
A typical adult itching dose is 25 mg three to four times a day, but the exact plan depends on the patient and the prescriber.
For anxiety, the daily total is usually divided, with a commonly used range of 50 to 100 mg per day.
When sedation is the goal, a single dose may be used rather than repeated daily dosing.
Children need a completely different calculation because hydroxyzine dosage is based on body weight and clinical need rather than a fixed adult amount.
Every paediatric dose should be recalculated in mg/kg and checked by a prescriber.
Adult dose ranges by indication
For pruritus, the dose is often spread across the day to keep symptoms under control.
For anxiety, the total daily amount may be divided to reduce peaks and improve tolerability.
For sedation, the prescriber may choose a single dose timed to the procedure or clinical need.
Paediatric dosing and syrup use
Paediatric hydroxyzine needs careful weight-based dosing and regular re-checking as the child grows.
Syrup is often preferred because it allows more accurate measurement than splitting tablets.
Dose adjustments in elderly patients and people with kidney or liver problems
- Elderly starting dose
- Often 10 to 25 mg, with cautious titration.
- Renal impairment
- Reduced dose and closer monitoring are needed.
- Hepatic impairment
- Reduced dose and closer monitoring are needed.
Older patients are more likely to feel the sedative and anticholinergic effects of hydroxyzine.
That is why lower starting doses are used and why some prescribers avoid it if another option is suitable.
Falls, confusion, and urinary retention are the problems pharmacists think about first in this group.
People with liver or kidney impairment can also accumulate the medicine more easily, so monitoring becomes more important.
Why lower starting doses are used
A small starting dose reduces the chance of excessive drowsiness and daytime impairment.
It is also a safer way to see how strongly a patient responds before increasing the dose.
Monitoring and when to avoid use
Accumulation can increase central nervous system effects and anticholinergic burden.
If the patient already has a high falls risk, cognitive impairment, or significant organ dysfunction, an alternative may be preferable.
Safety, side effects, and when hydroxyzine should not be used
| Common side effect | What patients notice | Practical impact |
|---|---|---|
| Drowsiness or sedation | Sleepiness, slower thinking | Can affect work, driving, and routine tasks |
| Dry mouth | Thirst, sticky mouth | May need extra fluids or sugar-free gum |
| Dizziness or blurred vision | Light-headedness, visual strain | Raises fall and driving concerns |
| GI upset | Constipation or nausea | Can affect daily comfort |
Hydroxyzine side effects are usually predictable and mainly related to its sedating and anticholinergic action.
The one most patients notice first is drowsiness, especially if they take the medicine during the day.
Dry mouth, headache, dizziness, blurred vision, fatigue, constipation, and nausea are also commonly reported.
For some people, that sedation is part of the reason the medicine was chosen, but for others it is the main drawback.
Early pregnancy is present.
The patient has a known allergy to hydroxyzine or excipients.
There is prolonged QT interval or a significant QT prolongation risk.
Severe hepatic or renal impairment makes use unsafe or unsuitable.
Common side effects patients notice first
The practical issue is often not a rare reaction but whether the patient can function normally.
Some people feel simply “knocked out”, while others mainly complain of a dry mouth and grogginess the next morning.
Contraindications and red flags
QT prolongation risk is an important red flag because hydroxyzine has been reviewed specifically for cardiac safety.
Other caution groups include patients with seizures, glaucoma, prostatic hypertrophy, arrhythmias, or significant organ impairment.
Drug interactions, driving advice, alcohol, and everyday precautions
- Other QT-prolonging medicines: increase cardiac risk and need careful checking.
- Sedatives and CNS depressants: can increase drowsiness and impairment.
- Alcohol: should be avoided because it can intensify sedation.
- Driving and machinery: not safe if drowsy, slowed, or visually affected.
- Work safety: extra caution is needed for night shifts, manual work, or any task requiring alertness.
Hydroxyzine interactions are mostly about sedation and cardiac safety rather than a long list of everyday food issues.
The main warning is to avoid combining it with other medicines that prolong the QT interval unless a prescriber has reviewed the risks carefully.
Alcohol is a common real-world problem because patients may not think of a “sleepy antihistamine” as something that needs the same caution as a sedative.
If the medicine makes a patient drowsy, driving should be avoided until the effects are clearly understood.
Medicines that increase risk
Other sedatives, CNS depressants, and QT-prolonging medicines are the main interaction groups.
That is why the pharmacist checks the full medicine list before supply.
Practical use advice in daily life
Taking the dose at the right time can reduce daytime impairment, especially when the main goal is night-time itch control or sleep.
Patients should also avoid alcohol and be cautious with work tasks that need steady attention.
Missed doses, overdose, and emergency response
- Take a missed dose when remembered unless the next dose is close.
- Do not double doses to “catch up”.
- If symptoms of overdose appear, seek urgent medical help immediately.
- Call emergency services if there is severe drowsiness, seizure activity, confusion, or a suspected arrhythmia.
A missed hydroxyzine dose is usually handled simply.
If it is remembered late, the patient can take it unless the next planned dose is nearly due.
Doubling up is not advised because the extra sedation can be more harmful than the missed dose itself.
What to do after a missed dose
The rule is straightforward: take it when remembered unless timing makes that unwise.
If in doubt, the safest pharmacy answer is usually to skip and return to the normal schedule.
Overdose warning signs and urgent action
Overdose symptoms can include extreme drowsiness, seizures, cardiac arrhythmias, and confusion.
Those are not symptoms to monitor at home for long; they need urgent medical attention.
Storage
- Store at 15 to 25°C.
- Protect from moisture, especially with blister packs and bottles.
- Do not freeze syrup.
- Keep out of reach of children.
Hydroxyzine storage is simple, but it still matters.
Room temperature storage helps preserve the product, and syrup should not be frozen.
Keeping the medicine out of children’s reach is essential because the sedating effect can be significant even at modest doses.
Home storage essentials
Blister packs should stay in their original carton when possible.
Bottles should be tightly closed after use, with the dosing cup kept clean and separate.
