Sharing prescriptions may seem like a great way to save money, but that can actually cause more damage than good. When a family member has leftover medication from a similar ailment, it can be tempting to skip the doctor and use the leftovers. But everyone reacts differently to medicine and certain medications don’t mix well. If you take medication without a doctor’s supervision, you can risk serious mishaps. A bad reaction can cause permanent damage to your body. Rather than taking the risk, it’s best to go to the doctor and get a prescription that’s specifically tailored to you. A good health insurance plan can help you pay for the cost.
