| Physicians and pharmacists recognize that some foods and drugs, when taken during the same period of time, can alter the body's ability to utilize a particular food or drug, or cause serious side effects. This brochure is designed to help you decide if your diet should be changed in any way to adjust to the effects of medicine you are using. It covers the interactions-that is, what can occur between foods and drugs-of the more commonly used medications, both prescription and nonprescription (or over-the-counter). This brochure should not be used in place of advice from a family physician or family pharmacist. Make sure your doctor knows about every drug you are taking, including drugs you obtain without a prescription order. If you have any problems related to medication, call your physician or pharmacist immediately. One drug may interact with another, in some cases creating serious medical problems. This brochure does not cover the interaction of one medicine with another. Interactions will vary according to the dosage, your age, sex and your overall health. Although alcohol is actually a drug rather than a food, its interaction with drugs is covered in this brochure because alcohol, when consumed while taking certain medications, can be extremely dangerous. It is a good rule of thumb to avoid consuming alcohol while taking any drug unless a physician or pharmacist indicates that the combination is acceptable. Cigarettes can also diminish the effectiveness of medication or create added hazards with certain medications. |
Medications should never be taken during pregnancy without the advice of your physician.
