The active element is known as diazepam. It is offered in a variety of brands with various names. Physical appearance (size, shape, or colour). They are all equally effective. There is no way to tell whether you are getting what's called "brand loyalty" by buying one brand over another. Although they are all forms of the same drug, they can have different effects on an individual. This is because people vary in their body shapes and sizes. The amount of Diazepam that someone takes will determine how much effect they will experience. If you take too much at once, it can be fatal. If you take less than recommended amounts, it can also be dangerous since it can cause depression without producing any relief from anxiety symptoms. Diazepam comes in oral form only. It is available as 10, 12.5, 15, and 20 mg tablets. Oral doses should be taken exactly as prescribed by your doctor. It may not be possible to take the dose as prescribed if you miss a dose or if you decide to use it later than advised. If you overdose on diazepam, you may feel very sleepy and confused and could fall asleep permanently without warning.
