Side Effects

Side effects are undesired reactions to medication, therapy, or medical procedures. They can range from mild to severe and can be temporary or long-lasting. Common side effects include nausea, dizziness, headaches, fatigue, and rash. More serious side effects can include organ damage, allergic reactions, and an increased risk of certain types of cancer. If you or someone you know is suffering from anaphylaxis or severe allergic reaction, it's recommended that you take an epinephrine class to know more about its side effects and treatment.

Side effects can occur when a drug interacts with certain enzymes, hormones, or other bodily substances. Patients may experience different side effects based on their genetic makeup, health history, and other individual factors.

Pharmacists, physicians, and other healthcare providers should inform patients of the potential side effects of any medication they are prescribed. Patients should always ask their provider questions and report any side effects they experience. Patients should also be aware of the potential for drug interactions and the risk of addiction.

When taking a new medication, it is important to ask your healthcare provider about possible side effects and to read the drug information sheet that is provided with the medication. It is also important to contact your healthcare provider if any unexpected side effects occur.
