Medicines are very beneficial for treating and preventing diseases.
Yet sometimes medicines can cause side effects and actually make a person feel worse. Side effects are more common as people age, so it's important to understand how to identify and prevent side effects. A person feeling dizzy, for example, may think it is a symptom of their heart disease, rather than a side effect from a new medication. Common side effects from medicines are dizziness, fatigue, constipation or headache. Side effects are more common in older people since many have several chronic diseases or conditions and, therefore, are often taking several medicines.
