Although the color or shape of the drug may be different, there is usually no difference in quality between generic and brand name drugs. You can ask your provider to prescribe generic drugs if they are available. Follow the dose and schedule written on the prescription label. Some medications are short-acting and need to be taken more often. Others stay in the body longer and don't need to be taken as often.
Some medications irritate the stomach, especially if there is no food in the stomach.
It is best to take these medications with meals. Other medications work better if your stomach is empty. Always take your prescribed medication until it is all gone. Don't change your dose without consulting your health care provider, and don't use medication prescribed for someone else. If you forget a dose of your medication, don't try to make up for it by taking more with the next dose.
