Why can't I sleep even after receiving a diazepam injection?

Diazepam injection, also known as Valium, is a medication commonly used for its sedative effects. Generally speaking, if a person is unable to fall asleep after receiving a diazepam injection, it may be due to drug tolerance, neurasthenia, insomnia, perimenopausal syndrome, or mania. Patients should receive targeted treatment based on the specific underlying cause. The detailed analysis is as follows:

1. Drug Tolerance: Long-term use of diazepam or other benzodiazepines may lead to increased tolerance in the body. This means higher doses are required to achieve the same effect. As tolerance develops, the original dose may no longer be effective in inducing sleep. It is recommended to switch to alternative medications under medical supervision to aid sleep.

2. Neurasthenia: Nervous fatigue or neurasthenia may reduce the effectiveness of diazepam. Neurasthenia is a condition characterized by dysfunction of the nervous system, presenting symptoms such as difficulty concentrating, fatigue, anxiety, and poor sleep quality. In this state, the drug may fail to effectively regulate sleep, making it difficult to fall asleep. Patients can take medications such as mecobalamin tablets or vitamin B12 tablets under medical guidance, while avoiding excessive physical or mental strain.

3. Insomnia: Insomnia may be related to psychological stress, anxiety, depression, or other emotional issues. Although diazepam may alleviate certain physical symptoms, persistent psychological factors can still interfere with falling asleep. Patients may be prescribed medications such as estazolam tablets or midazolam maleate tablets under medical supervision, along with developing healthy sleep habits.

4. Perimenopausal Syndrome: Perimenopausal syndrome refers to a range of physical and psychological symptoms women experience before and after menopause, including insomnia, mood swings, anxiety, and depression. These symptoms may disrupt the drug's ability to regulate sleep, rendering diazepam ineffective. Patients can be treated with medications such as Guizhi Fuling Pills or sertraline hydrochloride tablets under medical guidance, while maintaining a light and balanced diet.

5. Mania: Mania is a mood disorder characterized by extreme emotional excitement, increased activity, and insomnia. During a manic episode, diazepam may not adequately stabilize mood or promote sleep, resulting in difficulty falling asleep. Patients can be treated with medications such as sodium valproate oral solution or carbamazepine capsules under medical supervision.

If persistent inability to sleep occurs, prompt medical consultation is advised to prevent delayed diagnosis and potential harm to health.
