　　What is a correct way to take medicine? Reading the question you might think it ridiculous．Actually, how to take medicine means a lot．Knowing it will not only help you preserve the full benefit of your valuable medicine, but also save yourself from potential side effects．For many reasons, no prescription or over-the-counter(非处方的)drug is 100 percent effective in all people or situations．To preserve the full benefit of your medicine, experts say to follow these key steps：

　　Ask doctors for help．Discuss drug effectiveness with a doctor before getting a prescription．The doctor can help you explain effectiveness data in product instructions．You can also consult a chemist when buying over-the-counter medications．

　　Store drugs properly．For instance, never store aspirin in the bathroom or the refrigerator．That^s because aspirin, like other drugs, can lose effectiveness in damp conditions．Most prescription drugs today come with special storage instructions．Also, some drugs, such as the antibiotic tetracycline, become ineffective when they are exposed to sunlight．

　　Do you know how long you should use a certain medicine? Our human body is very smart．It doesn't like any foreign chemical．That's why the body builds up tolerance to many drugs, such as some sleeping pills, and pain medications．If a drug that once was effective no longer seems to help you, consult a doctor before you want to increase the amount of it．

　　Cutting a sustained-release(药效持久的)pill can make a drug ineffective or even dangerous．That's because too large a dose of a medicine will be distributed quickly．Also avoid emptying capsules into drinks, say coca cola, milk, juice or food like porridge and soup．So take the pill in a correct way．

　　Do you know when to use medicine? You are advised to use medicine at the right time of the day．The instruction of the medicine Renova recommends applying the product at night．The active drug can be destroyed by sunlight．Also, applying two medicines to your skin at the same time might make them both ineffective．Taking drugs at recommended times, such as before meals, can increase absorption．

　　Some people may store medicine they bought years ago．In actual fact, over time, many drugs experience chemical changes．So pay attention to expiration(截止)dates listed on labels or ask your chemist a drug ^ s shelf life．Don ^ t hesitate to throw old pills if possible．

　　As you can see, taking medicine correctly is very important for many reasons, so make sure you follow these tips．
