Sonata belongs to a class of substances called benzodiazepine-related medicinal products, which consists of preparations with hypnotic actions.
Sonata will help you to sleep. Sleeping problems donot usually last long, and most people only need a short course of treatment. The duration of treatment should usually vary from a few days to two weeks. If you still have problems sleeping after you have finished your capsules, contact your doctor again.
hypersensitivity an allergy to zaleplon or to any other ingredients of Sonata sleep apnoea syndrome stopping breathing for short periods while asleep severe kidney or liver problems myasthenia gravis very weak or tired muscles severe breathing or chest problems
If you are in any doubt about whether you have any of these conditions, do ask your doctor. Children under 18 years of age must not take Sonata.
Never drink alcohol while you are being treated with Sonata. Alcohol can increase the undesirable effects of any medicine taken to help you sleep. Use with extreme caution if you have ever been addicted to medicines or alcohol. If you are taking any medicines belonging to the sleep inducing group, including Sonata, there is a possibility that you may become dependent on them. Once physical dependence has developed, abrupt termination of treatment may be accompanied by withdrawal symptoms. These may consist of headaches, muscle pain, extreme anxiety, tension, restlessness, confusion and irritability. 3
Do not use Sonata or any other sleeping medicine for longer than your doctor tells you to. Do not use a second dose of Sonata within a single night. If your sleeplessness persists or worsens after a short course of Sonata treatment contact your doctor. There is a chance that you may experience a certain type of temporary memory loss amnesia and lack of coordination when taking sleep medicines. This can usually be avoided if you remain inactive for at least 4 hours after taking Sonata. There is a chance that you may experience somnambulism sleepwalking, including eating or driving while not fully awake with no memory of the event. If you experience these events, contact your doctor immediately. Reactions like restlessness, agitation, irritability, aggressiveness, abnormal thinking, delusion, rages, nightmares, depersonalisation, hallucinations, psychoses, inappropriate behaviour, extroversion that seems out of character and other behavioural effects have been reported following use of any medicines belonging to the sleep inducing group, including Sonata. These reactions may be active substance-induced, spontaneous in origin, or a result of an underlying psychiatric or physical disorder. They are more likely to occur in the elderly. If you experience these events, contact your doctor immediately. Rare cases of severe allergic reactions have been reported. An allergic reaction may include a rash, itching, difficulty breathing or swelling of the face, lips, throat or tongue, or nausea and vomiting. If you experience any of these events, contact your doctor immediately.
Do not take anyother medicines without asking your doctor or pharmacist first. This includes medicines that can be bought without a prescription. Some can cause drowsiness and should not be taken while taking Sonata.
When Sonata is taken with other medicines that act on the brain, the combination may make you more drowsy than it should. Be aware that such combinations may cause you to feel drowsy the next day. These medicines include: substances used in the treatment of mental conditions (antipsychotics, hypnotics, anxiolytics/sedatives, antidepressants), medicines used for strong pain relief (narcotic analgesics), medicines used for the treatment of seizures/convulsions (antiepileptic medicines), medicines used for loss of feeling/ insensibility (anaesthetics), and medicines used in the treatment of allergies (sedative antihistamines).
You should tell your doctor or pharmacist if you are taking cimetidine (a stomach medicine) or erythromycin (an antibiotic).
It is not recommended that you take Sonata with or immediately after eating a large meal as it may work more slowly. Swallow the capsule(s) with a small glass of water. Never drink alcoholwhile you are being treated with Sonata (see ?Take Special care with Sonata?).
Tell your doctor if you are or intend to become pregnant. Sonata should not be taken at these times because there are not enough clinical data available to assess its safety during pregnancy.
Tell your doctor if you are breast-feeding. Sonata should not be taken at this time because there is not enough clinical data available to assess its safety during breast-feeding.
Sonata may make you feel drowsy, cause loss of concentration or memory or muscle weakness. This feeling may be even worse when you sleep for less than 7 to 8 hours after taking your medication. If affected do not drive or operate machinery.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
Always take Sonata exactly as your doctor has told you. You should check with your doctor if you are not sure.
The usual dose for adults is 10 mg just before going to bed, or after you have gone to bed and you are having difficulty falling asleep. You should not take a second dose within a single night.
There are different doses for people who are 65 or older, and those who have mild to moderate liver problems:
65 or older: Take one 5 mg capsule
Mild to moderate liver problems: Take one 5 mg capsule
Sonata has been designed, so that if the contents of the capsule are dissolved in liquid, the liquid will change colour and become cloudy.
If an overdose has been taken you may become increasingly drowsy very quickly, with high doses probably leading to a coma.
Just take your next capsule at the usual time, then go on as before. Do not try and catch up on the doses you have missed.
On stopping treatment, your original sleeplessness may return and you may experience symptoms such as mood changes, anxiety, and restlessness. If you suffer from these symptoms, ask your doctor for advice.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
