1. What is Nodisen and what is it used for

The active substance of Nodisen is diphenhydramine hydrochloride. Diphenhydramine is classified as a sedating antihistamine.
Nodisen is indicated for short-term use in occasional insomnia in adults.
Occasional insomnia may occur especially when there are difficulties falling asleep, frequent nighttime awakenings, early morning awakenings related to stress or a change in time zones.
Transient sleep disturbances usually last a few days and can be caused by various factors, such as stress, fatigue related to a change in time zone, personal problems, or work-related problems. The use of Nodisen will reduce the time to fall asleep and increase the depth and quality of sleep.
Sleep disturbances can have a negative impact on physiological processes and lead to a decrease in psychophysical fitness. Insomnia is said to occur, among other things, when: the time to fall asleep exceeds half an hour, the total time spent awake during the night lasts longer than half an hour, such disturbances occur at least three nights a week, and poor sleep quality causes fatigue or decreased psychophysical fitness during the day.
Taking medication is not the primary method of treating sleep disorders and should be limited to short-term use only.
Prolonged poor sleep quality may be a symptom of mental and physical disorders that require other treatment methods, which should be assessed by a doctor. Consulting a doctor is also necessary in case of symptoms other than insomnia. Failure to properly diagnose the cause of sleep disturbances and their treatment may lead to a risk of health loss. Treating the underlying disease that causes sleep disturbances is a necessary condition for a lasting improvement in sleep quality.

The medicine should not be used to treat chronic sleep disorders.

The treatment period should be as short as possible. The medicine should not be used for more than 7 days without consulting a doctor. If after 7 days there is no improvement or the patient feels worse, they should consult a doctor.
