Description

What Pregabalin Is (UK Context)

Generic name: Pregabalin
Common UK brand names / products:

• Lyrica (Pfizer) — original brand
• Rewisca — generic hard capsules (25 mg – 300 mg) licensed for epilepsy & anxiety in UK†(Medicines Resources)

Pregabalin is a prescription-only medicine used to calm overactive nerves. It’s part of a family of medicines called gabapentinoids. In the UK it is classified as a Class C controlled drug due to potential misuse and dependency risks.†(GOV.UK)

2. Epilepsy

• Adjunctive therapy (with other medications) for partial-onset seizures in adults.

3. Generalised Anxiety Disorder (GAD)

• Licensed for GAD in adults, though it’s often considered only after other treatments.†(nhs.uk)

Important Safety & UK Regulatory Notes

Controlled Drug Status

Pregabalin (and gabapentin) are Class C controlled substances in the UK. This means stricter prescribing and dispensing rules to reduce misuse and diversion.†(GOV.UK)

Breathing Risks

Severe respiratory depression (breathing difficulty) has been reported, even without opioids — especially in people with breathing or neurological problems, kidney impairment, older adults, or those on other sedative drugs.†(GOV.UK)

Dependence & Misuse

There are reported cases of dependence, misuse, and withdrawal symptoms with pregabalin, particularly at higher doses or in people with a history of substance misuse.†(GOV.UK)

Common Side Effects

Many people experience mild effects that often lessen over time:†(nhs.uk)

Very common

• Sleepiness / feeling drowsy
• Dizziness
• Headaches

Common

• Blurred vision
• Mood changes
• Nausea / diarrhoea
• Feeling tired
• Weight change

Less common but serious (seek help)

• Allergic reactions (rash, swelling)
• Significant breathing difficulty (see your doctor urgently)
• Visual changes
• Severe withdrawal symptoms if stopped suddenly
• Rare serious skin reactions (eg. Stevens-Johnson syndrome)†(Medicines.org.uk)

Important Precautions

✔ Tell your doctor if you have:

• Kidney problems — dose changes may be needed.†(nhs.uk)
• Respiratory disease, COPD, or lung weakness.†(GOV.UK)
• A history of drug or alcohol misuse.†(GOV.UK)
• Pregnancy or breastfeeding — discuss benefits vs. risks.†(nhs.uk)

✔ Do not stop abruptly — tapering is safer to avoid withdrawal symptoms.†(nhs.uk)

✔ Alcohol and other sedatives can increase drowsiness and breathing suppression risks — avoid or minimise.†(GOV.UK)

Collecting Pregabalin on the NHS

• Because it’s a controlled drug, the pharmacy might ask for ID and require a signed prescription each time.†(nhs.uk)
• It’s best to hand in repeat prescriptions several days early to avoid running out.†(nhs.uk)
