When it comes to strength, the two drugs are fairly similar. Both Triazolam (Halcion) and Xanax are considered to be relatively strong drugs. Triazolam is a bit more potent, however, so it may be more effective at treating anxiety or insomnia. If you're looking for a stronger drug, triazolam might be the better option. However, it's important to remember that strength isn't the only factor to consider when choosing a medication. Both drugs can cause side effects, so it's important to talk to your doctor about which one is right for you.
