As with any drug or medication you need to take every precaution when using Dramamine. Motion sickness and Dramamine may spell trouble for some cruisers. Consult with your doctor before using Dramamine if you already have an existing medical condition. Also Dramamine should NOT be taken by pregnant women or those who are nursing. Who else should not use this drug?
If you are cruising with children below two years of age, do not give them Dramamine under any circumstances whatsoever and if you plan on administering the motion sickness tablets to an older child, always consult a doctor in advance, in other words, consult your doctor BEFORE going on the cruise.
Others who should seek medical advice before using Dramamine for motion sickness are persons who suffer from any heart diseases, glaucoma and/or anyone who has a prostate problem. But for the rest of us, Dramamine might be cruise vacation saver.
