Heher, MD: "Blood pressure pills, antibiotics, birth control pills, and most other prescription and over-the-counter medications are sold under different names in different countries (even if they're manufactured by the same company).  When you travel, make sure you know the commercial name of the  medications you and your family use regularly. You should also know the generic (also known as chemical) name of these medications, which is more likely to be familiar to physicians and pharmacists.  Also, a medication that's available in 5, 10, and 20 mg tablets in the U.S. may only be available in 10 mg tablets elsewhere. Carry an adequate supply of all medications in case of delay finding an equivalent supply. Pack at least half of your supply in a carry-on bag.  Some medications, such as oral contraceptive agents, are particularly difficult to duplicate in their exact formulation overseas. You should consider obtaining these medications at home for the duration of your entire stay. Bring copies of all medication prescriptions, and glasses and contact lens prescriptions. Disposable contacts should probably be supplied from the home. An extra pair of glasses is a necessity.  Write down the ingredients of the over- the-counter medications you use, so a physician or reliable pharmacist can suggest something similar if the exact formulation sold in your home country isn't available. Avoid problems with curious customs agents by leaving all medications in their original bottles and by carrying a letter from the prescribing doctor explaining why the medications are necessary.  This is critical for medications that are subject to abuse, such as narcotics. If you receive allergy injections or injections of other medicines at home, be certain to get a detailed letter from the prescribing physician describing the exact components of the shots."
