Medicine can be delivered to body in many different ways.1. Oral-by mouth2. Topical- applied to skin3. Inhaled- fine mist or powder4. Injected- by shot into blood stream
Medicines can have side effects- reactions to medicine other that what was intended
When medicines are taken together or when a med is take with certain foods the combo may have different effect than when taken alone. This is called a Drug Interaction.
Additive interaction- when meds work together in a positive way. Ex.: an anti-inflammatory and muscle relaxant may be prescribed to treat joint pain
Synergistic effect-2 or more meds that result in a greater effect than when each is taken alone-when one med increases the effect of another.
Antagonistic interaction- occurs when one med is cancelled or reduced when taken with another. Ex.: if using an antibiotic - some birth control pills do not work as intended.
When some one takes a med for a long time = body gets used to it and problems may occur.
Tolerance- body get used to med and needs more of it to have same effect. Sometimes reverse tolerance is also experienced
With drawl- a person may become physically or psychologically dependent
