Short-acting benzodiazepines (e.g. alprazolam) need to be taken three to four times a day, which is not very practical. For this reason, they may not be suitable for long-term administration. They may be more useful for immediate, one-off alleviation of anxiety or distress and may thus be a good option for p.r.n. use.
Add 10 years to the date of issuance if you were over 16 when you got the passport, or five years if you were 15 or younger. For instance, if you received a passport in November 2004 at age 25, your passport expires in November 2014. If you got the passport at age 14, it expired in November 2009.
For holders of U.S. passports, the expiration date is on the inside front cover, next to the passport holder's photo. After that date, the passport is no longer a valid travel document. Some countries, however, refuse to allow entry to anyone holding passport that expires in less than three or six months. good source of up-to-date information about passport validity is the U.S. Department of State's travel website (travel.state.gov), which lists entry requirements by country. Would-be travelers should also consult the embassy websites of countries they want to visit.
