Does Pliva 434/433 Feel Like Xanax?
Although Xanax is similar to trazodone, they are different drugs. While trazodone is an antidepressant, Xanax is a benzodiazepine anti-anxiety drug.
Benzodiazepine drugs increase activity at receptors in your brain, known as GABA receptors. This process slows down your central nervous system (CNS), helping you feel calmer and relaxed.
Another main difference is that Xanax and other benzodiazepines can be addictive. On the other hand, trazodone is not.

What to Discuss With Your Healthcare Provider Before Taking Pliva 434
Are trazodone and Xanax the same thing?
No. Trazodone is an antidepressant, while Xanax is a benzodiazepine. Benzodiazepines are controlled substances under the U.S. Drug Enforcement Agency. This means that Xanax, unlike Trazodone, has a much higher potential for misuse and abuse. Also, Xanax helps to treat panic disorders, including panic attacks or anxiety. Xanax would not be a suitable option for depression.
Does trazodone work right away for sleep?
For those who are taking trazodone for insomnia, doctors will recommend taking the drug during bedtime. Because trazodone causes drowsiness, which may extend even a day after you take the pill, you must practice caution, especially in activities that require alertness.
Trazodone is not approved as a sleeping pill, but its side effect of increased sleepiness is the reason why it may help you fall asleep.
How long do you sleep on trazodone?
Trazodone helps provide a better night’s rest by letting individuals sleep approximately 7 to 8 hours.
Does Trazodone affect memory?
Trazodone may affect memory. A side effect reported in people taking the drug is difficulty concentrating or remembering.
What happens if I miss a dose?
There is no problem when it comes to a missed dose. Individuals just need to take the dose as soon as they remember (assuming it is not close to the next dose).
Individuals should remember to avoid taking a double dose of the drug.
