Alcohol can interact negatively with diazepam, so it’s not a good idea to drink while you’re taking it
Benzodiazepines can also interact with one another, so it’s not a good idea to take diazepam if you are already taking another benzo. If in doubt, check with a doctor
If you’ve been prescribed diazepam and you notice a tolerance starting to develop (you need to keep taking more to get the same effect) speak to your doctor- don’t just start increasing your dose yourself
Don’t suddenly stop taking them, or you may start to experience symptoms of withdrawal- these can range from a return of your original symptoms (possibly even worse than before) to totally new symptoms
If you have become addicted to diazepam, the symptoms of abruptly stopping are likely to be even worse- it’s important to get proper medical advice on how to reduce your intake slowly
It’s also possible to become psychologically dependent on the drug (feeling like you need it all the time)- if you think this is happening, see your doctor as soon as possible, but don’t suddenly stop taking it.
