Prescription anxiolytics and sedatives: dependence, OTC alternatives

Benzodiazepines and "Z-drugs" are among the most prescribed psychotropic medicines in Romania — but also among the hardest to stop. According to ANMDMR and National Anti-Drug Agency reports, chronic prescriptions often exceed the internationally recommended duration. Here is how the classes differ, what OTC alternatives exist, and why "sleep on prescription" often becomes a problem in itself.

The main classes and their mechanisms

• Benzodiazepines (alprazolam, diazepam, lorazepam, bromazepam, clonazepam, midazolam): potentiate GABA-A → anxiolytic, sedative, muscle relaxant, anticonvulsant.
• Z-drugs (zolpidem, zopiclone, eszopiclone): selective for the α1 subunit of GABA-A → more hypnotic, less anxiolytic.
• Buspirone (Spitomin): a partial 5-HT1A agonist — a non-sedating anxiolytic with no dependence potential. Onset 2-4 weeks.
• SSRI/SNRI (escitalopram, sertraline, venlafaxine, duloxetine): first line for generalised anxiety disorder, panic, phobias — onset 4-6 weeks.
• Hydroxyzine (Atarax): a first-generation antihistamine with anxiolytic properties, no dependence, but daytime sedation.
• Pregabalin (Lyrica) — an anxiolytic in GAD, caution: abuse potential reported in Europe.

The profiles of the most common ones in Romania

The recommended limits and the dependence problem

The EMA and BNF recommendations, reflected in the SmPCs approved by ANMDMR: benzodiazepines for a maximum of 4 weeks (including tapering), Z-drugs for a maximum of 2-4 weeks. In Romanian practice, prescriptions often exceed 6-12 months — the situation leads to physical dependence (tolerance + withdrawal on stopping) and psychological dependence.

Withdrawal after months of use can be severe: rebound anxiety, worsened insomnia, tremor, sweating, in rare cases seizures. Stopping is done with tapering over >8-12 weeks, under medical supervision, possibly switching to diazepam (a long half-life) for smooth titration.

Regulation and prescribing in Romania

All benzodiazepines and Z-drugs are P-RF — a prescription retained at the pharmacy. Many are on the list of narcotic and psychotropic substances under Law 339/2005, section III. Dispensing is done strictly on the basis of the prescription, with a maximum duration of 30 days and a limited quantity per prescription. CNAS reimburses 50% in certain indications (List B/C2), but the criteria are strict.

OTC alternatives for mild anxiety and occasional insomnia

• Melatonin 1-3 mg 30-60 min before bedtime — useful in sleep-onset insomnia, jet lag, shift workers. Available OTC in Romania. Studies: a modest but consistent effect.
• Valerian — standardised extracts (300-600 mg extract). The meta-analytic evidence is modest, but the safety profile is good.
• Passionflower, magnolol, St John's wort — products such as Sedatif PC, Persen, Faringosept Calm. Caution: St John's wort interacts with many medicines (contraceptives, anticoagulants, antiretrovirals) — check with the pharmacist.
• Doxylamine (a component in Sanval Forte / Somina) — an OTC hypnotic, effective in the short term.
• Magnesium, vitamin B6 — modest effects, but useful in a deficiency context.

First line for chronic anxiety: not benzodiazepines

All the guidelines (NICE, APA, BAP) recommend for generalised anxiety disorder and phobias:

1. Cognitive behavioural therapy (CBT) — the gold standard, comparable to medication, without side effects.
2. SSRIs (escitalopram 10-20 mg, sertraline 50-200 mg, paroxetine) — the first pharmacological line.
3. SNRIs (venlafaxine, duloxetine) — an alternative.
4. Buspirone, hydroxyzine — non-benzo anxiolytics.
5. Benzodiazepines — only short term, in a crisis, under 4 weeks.

Sleep hygiene — what changes things without medication

• Fixed bed and wake times (including at the weekend).
• No bright screens 1-2 hours before bedtime.
• Caffeine — stop after 2 p.m.
• Alcohol worsens sleep architecture — you fall asleep fast, but it fragments REM.
• A cool room (18-20°C), dark and quiet.
• Physical activity in the first half of the day.
• Breathing techniques (4-7-8, box breathing) or guided meditation — effective in prolonged sleep onset.

Frequently asked questions

Can I mix alcohol with Xanax just at the weekend?

No. The combination markedly increases the risk of respiratory depression and accidental death. Including "one beer".

How long can I take zolpidem?

SmPC recommendation: 2-4 weeks, ideally intermittently (3 nights/week). Longer — risk of dependence, parasomnias (sleepwalking), anterograde amnesia.

Can I stop a benzodiazepine taken for 2 years on my own?

Definitely not abruptly. Supervised tapering, possibly with a switch to diazepam.

Is melatonin addictive?

No. It is an endogenous hormone; the OTC doses are physiological.

Are SSRIs addictive?

No, but they can cause a discontinuation syndrome on abrupt stopping (dizziness, brain "zaps") — taper over 4-8 weeks.

Is pregabalin safer than alprazolam?

Fewer interactions, no marked respiratory effect, but it has an abuse potential reported in Europe — it is not "neutral".

Differentiating the effects by half-life

The half-life changes the choice in a way that is not intuitive for the patient:

• Very short (zolpidem 2-3h, midazolam 1-2h): ideal for sleep-onset insomnia; minimal risk of a morning "hangover", but maximum risk of rebound and parasomnias.
• Short-medium (alprazolam, lorazepam, oxazepam): useful in panic attacks, occasional anxiety; requires repeated dosing, with rebound risk between doses.
• Long (diazepam 20-100h, clonazepam 18-50h): stable in plasma, useful in tapering; an accumulation risk, especially in the elderly and the hepatically impaired.

For fragmented sleep (waking at 3-5 a.m.), zolpidem is already eliminated — without effect. Here extended-release zolpidem (Stilnox CR) or zopiclone, which last longer, is sometimes used.

Supervised tapering — how it goes concretely

For a patient on alprazolam 1 mg three times a day for 18 months, abrupt stopping is dangerous. A pragmatic scheme, under medical supervision:

1. Conversion to diazepam — equivalent to ~50 mg diazepam (1 mg alprazolam ≈ 20 mg diazepam, but the conversion is done with a margin of caution).
2. Stabilisation on diazepam for 2-4 weeks.
3. Reduction by 10% of the current dose every 1-2 weeks — adaptable to symptoms.
4. Towards the end (under 5 mg diazepam/day), even smaller steps (1 mg every 2 weeks).
5. Possible bridging with pregabalin or gabapentin for withdrawal anxiety — controversial, but sometimes useful.
6. Concurrently: CBT, sleep hygiene, physical exercise.

Resources for the patient: the Ashton protocol (the Ashton manual, free online), support groups. The total process: 6-18 months in chronic patients. There is no "quick fix".

Polypharmacy and major interactions

• Benzo + opioid — a risk of respiratory depression, death. FDA Black Box Warning. If both are necessary, minimal doses and monitoring.
• Benzo + alcohol — synergistic.
• Z-drugs + food — recent food increases zolpidem absorption → morning sedation.
• Pregabalin + opioid — an additional risk of respiratory depression.
• SSRI + tramadol / triptan / linezolid — a risk of serotonin syndrome.

Non-drug sleep training: CBT-I

Cognitive behavioural therapy for insomnia (CBT-I) is the gold standard. Key components:

• Sleep restriction: you reduce the time in bed to how much you actually sleep (for example 5-6 hours), then increase it gradually.
• Stimulus control: the bed = only sleep and sex; you get up if you are not asleep within 20 minutes.
• Cognitive restructuring: you counter catastrophic thoughts about sleep.
• Sleep hygiene (see above).
• Relaxation techniques: breathing, mindfulness.

Typical cases and strategy

• An isolated panic attack: alprazolam 0.25-0.5 mg sublingual as needed, max 4-6 times/month. CBT education.
• Chronic GAD: escitalopram 10 mg/day, titratable, + CBT, + a benzo only in the first 2-4 weeks of SSRI initiation if anxiety is severe.
• Occasional sleep-onset insomnia (travel, schedule change): melatonin 1-3 mg.
• Chronic insomnia: CBT-I is first line. Medication if CBT is unavailable — short doxylamine, mirtazapine 7.5 mg, trazodone 25-50 mg (off-label but common).
• A patient on Xanax for 12 years who wants to stop: referral to a psychiatrist for supervised tapering — never "on the sly".
