Warnings and precautions
This medicine causes drowsiness and unsteadiness, particularly when you start it or the dose goes up. Do not drive or operate machinery until you know how it affects you. Never stop it suddenly. Stopping abruptly can cause anxiety, sleeplessness, sweating and, in people taking it for epilepsy, fits. Your doctor will taper it. Tell your doctor about any change in mood or any thoughts of harming yourself. The dose is usually built up slowly from a low starting point — follow the schedule your doctor gave you rather than jumping to the full dose. Pregabalin comes under Schedule H1 from 16 November 2026 and will then need a prescription and a pharmacy register entry.
Do not take Sonaxa if
Not for anyone with a known allergy to this medicine or to any ingredient in the pack.
Interactions with other medicines
Opioid painkillers, alcohol, sleeping tablets and antihistamines all add to the drowsiness, and the combination with opioids can dangerously slow breathing. Antacids reduce the absorption of gabapentin — separate them by a couple of hours.

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Expert advice for Sonaxa 50 mg Capsule
