What is Sominex Tablets

Sominex is an over-the-counter sleeping aid. It is formulated to help patients suffering from temporary sleep issues, disturbances, and insomnia. The active ingredient in Sominex is promethazine hydrochloride, which is an antihistamine. The medication works by blocking the creation of histamine in your body, which makes you feel sleepy. Sominex can be used when your sleep routine changes, or even when you are jet-lagged. The medication decreases the amount of time you take to fall asleep, gives you a deeper sleep, and ensures that you awaken well-rested and fresh. By improving the quality of your sleep, it also indirectly impacts your mood positively.

How effective is Sominex?

The active ingredient in Sominex - promethazine hydrochloride - is an antihistamine. It blocks the production of histamine in your body, which results in drowsiness and deep sleep. Ideally, you should start feeling sleepy in 1-2 hours of taking medicine. Most patients report that they fall asleep within 5-10 minutes and stay asleep for more than five hours. Sominex is therefore extremely effective in combating sleep-related issues like insomnia. It considerably improves sleep quality, in turn improving your mood throughout the day. It gives you a feeling of being well-rested and relaxed. So if you are struggling to fall asleep, Sominex might help. However, it is vital to investigate the underlying causes of sleep disturbance. If it is a temporary disturbance in sleep pattern due to jet lag or change in your routine, Sominex provides considerable relief. But if your sleep issues are persistent, it is best to consult your doctor and seek professional help.

Can I buy Sominex online?

Sominex is an over the counter medicine for better sleep. You can buy it online to improve sleep during temporary phases of sleep disturbance. But we recommend checking with your GP to rule out all possibilities of other, more complicated underlying conditions that are impacting your normal sleep. You can also book an appointment with Click Pharmacy doctors for expert consultation. For quick delivery, you can choose our Next Day Delivery Service. Simply select the desired delivery service at the check out stage of the process.

What dose should I choose?

Sominex works best when taken at bedtime. It is recommended to have one tablet a night, with some water. You should start feeling sleepy in an hour or two. Sominex is a temporary cure for sleep disturbance, and accordingly, at one time, the medication should only be taken for seven nights maximum. If you still have problems falling asleep after seven nights of taking Sominex, we recommend seeing your doctor. 

How should I use Sominex?

Sominex comes in tablet form. To alleviate temporary sleep disturbances, take one tablet a night with some water. The active ingredient in Sominex reduces histamine release in the body, making you drowsy. You should start feeling sleepy in 1-2 hours of taking the medicine. Most patients report that they fall asleep within 5-10 minutes after feeling drowsy and stay asleep for more than five hours. At one time, the medication should only be taken one a night for seven nights maximum. It is best to consult your doctor if you still have problems falling asleep after seven nights of taking Sominex.

How does Sominex work?

The active ingredient in Sominex is promethazine hydrochloride, an effective antihistamine. What histamine does to the body is induce alertness. It helps to promote and stabilize wakefulness. Thus, changes in sleep pattern or in histamine levels might affect sleep, and how quickly or deeply you sleep. By inhibiting histamine production in the body, Sominex ensures that wakefulness and alertness are reduced. Hence, within two hours of taking the medication, you start feeling drowsy, and 5-10 minutes after that you fall asleep. After taking Sominex, most patients slept through the night - for over five hours. Even those with jet lag or disturbed sleep cycles report improved sleep quality and refreshed, relaxed mood during the day.

How long do I use Sominex before I notice a difference?

Sominex is designed to be a temporary fix for sleep disturbances and insomnia. At one time, the medication should only be taken one a night for seven nights in a row. If after seven days you still have sleep-related issues, there might be underlying problems. Hence, it is advisable to consult your doctor if you still have problems falling asleep after seven nights of taking Sominex.

What are the side effects of Sominex?

Do not take Sominex for more than seven nights consecutively. While using Sominex, you might feel some side effects. It is best to get your doctor's advice on these side effects. Sominex works by restricting histamine in the body, causing drowsiness and better sleep. Sometimes, you might feel drowsy even after you wake up. You might also feel confused and dazed or even clumsy and disorientated. This is normal, but if you feel severe debilitation, tell your doctor. It is advisable not to drive or use heavy machinery while taking Sominex. Other side effects include stomach issues like diarrhoea or indigestion. You might also feel your mouth going dry.

Additionally, some people report difficulty in passing urine. You might feel restless, excited, sick, or sensitive to sunlight. You might experience a rash on the skin, or blocked and stuffy nose. Be mindful of your symptoms and tell your doctor if you feel anything out of the ordinary. Lastly, if you are allergic to the ingredients of the medicine, do not use Sominex. In case of accidental overdose, please contact the nearest hospital and your doctor.

When shouldn't I use Sominex?

If you are allergic to any ingredients used in making Sominex, do not use it without consulting your doctor. The medication is designed for adults and children over the age of 16. Sominex is also not advisable for the elderly, so ask your doctor if it is okay for you to take Sominex if you are above the age of 65. Avoid drinking alcoholic beverages while using Sominex. Also, if you have taken one tablet already and still can't sleep, do not take another one. It is recommended to take only one tablet at one time. Do not use Sominex for more than seven nights consecutively.

What Is the difference between Sominex and Nytol Herbal Night Time Sleep Aid?

Nytol Herbal Night Time Sleep Aid is a traditional, herb-based medicine. It contains valerian root, a perennial flowering plant that is native to Eurasia. Valerian root has been widely used in traditional medicine for its sleep-inducing qualities. It also has hop strobile, a natural sedative, and passionflower extracts that are soothing and relaxing to the body. In addition to being a sleeping aid that improves the quality of sleep, Nytol Herbal Night Time Sleep Aid provides relief from mild anxiety too. It brings a sense of calm, making patients sleep better and more relaxed.

This helps to decrease the amount of time you take to fall asleep, gives you a deeper sleep, and ensures that you wake up well-rested, alert, and fresh. In fact, by significantly improving the quality of your sleep, it also enhances your mood considerably.
