- which is more effective in stopping a full blown panic attack Xanax or diazepam?
I would have to pick alprazolam (xanax), faster typical onset, and strength. Though diazepam (Valium) has been around for a long time, and has a very studied history.
- does diazepam interfere with the contraceptive pill??
No.
- I've read somewhere that the contraceptive pill interferes with the effectiveness of diazepam. Is that true??
There should be no interaction between the birth control and diazepam. You didn't list which contraceptive you are taking, so to be 'extra' sure simply call your local pharmacy.
- the doc told me that I could take up to two tabs at a time when needed. Is taking two 5 mg normal
Yes, it is absolutely normal. 10mg of diazepam is not a 'strong' or 'high' dose.
In fact, I almost hesitate to state this for placebo possibilities, but a half 0.5mg's of Xanax is equivalent to 10mg's of Valium. If you were taking 0.25 or 0.5mg of Xanax before, then your dose is equivalent.. if you were taking more you might not find 10mg's as effective.
However, before discounting the valium it is in the 'family' of benzodiazepines,.. but the effects aren't EXACTLY like alprazolam. Take it, give it a shot, it should do the job. If you find it to be ineffective, don't be scared to print the following (or any) equivalency chart to show why it might not be as effective.

Though if the doctor was doing a proper job, you were taking no MORE than 1mg of xanax at any one time, and hopefully 0.25 or 0.5mg.
Hope that helps,
