Medicines can treat and cure many health problems.
However, they must be taken properly to ensure that they are safe and effective. Many medicines have powerful ingredients that interact with the human body in different ways, and diet and lifestyle can sometimes have a significant impact on a drug's ability to work in the body. Certain foods, beverages, alcohol, caffeine, and even cigarettes can interact with medicines. This may make them less effective or may cause dangerous side effects or other problems. When you take medicine, be sure to follow your doctor's instructions carefully to obtain the maximum benefit with the least risk.
