This article contains some general tips for women travelers. Tips for women at individual destinations (such as, say, appropriate dress when visiting a temple, especial safety issues) are addressed in those articles. This article covers more general issues for women travelers.
Many women, particularly those between 10 and 55, travelling for an extended period of time will have their period while travelling. Some extra preparation might be needed to deal with it.
Pack enough supplies of your usual menstruation product (tampons or pads), particularly if you are going to a less developed country where they might not be available easily.
If you use any pain killers for cramps, take them along after checking their legality at the destination. If crossing international borders, leave them in their original packaging so that customs can determine what they are.
For women doing extended travel in areas where obtaining and disposing of normal menstrual products is annoying, consider reusable menstrual products. The primary products in this category are the suction cups: the silicone Diva Cup and the rubber Keeper. These are non-absorbant, reusable and do not even need to be rinsed before re-insertion every time.
Some women travelers (particularly athletes and honeymooners, but others too) might consider using the contraceptive pill to postpone or skip a period. Extended cycle pills such as Seasonale (one period every three months, rather than every 28 days) are approved for use in some countries, however normal monophasic pills can be used to skip periods as well, by skipping the different coloured sugar placebo pills. Discuss this use with your prescribing doctor.
