### Introduction Antibiotics are prescription drugs that help treat bacterial infections, including dental infections. They work by killing the bacteria causing the infection or by stopping the bacteria from growing and multiplying. However, antibiotics can have side effects. ### Common Side Effects - **Gastrointestinal Issues**: Many antibiotics can cause stomach upset, nausea, vomiting, and diarrhea. To manage these, ask your doctor if you should take your antibiotic with food. - **Photosensitivity**: Some antibiotics can make your skin more sensitive to sunlight, increasing the risk of sunburn. Use sunscreen and wear protective clothing when outdoors. - **Allergic Reactions**: Symptoms can include hives, swelling, and difficulty breathing. If you experience these, stop taking the drug and seek medical help immediately. - **Yeast Infections**: Antibiotics can disrupt the balance of good bacteria, leading to yeast infections. Symptoms include itching and discharge. Over-the-counter treatments are available, but consult your doctor for severe cases. - **Tooth Staining**: Antibiotics like tetracycline can cause permanent tooth staining in children under 8 and in unborn babies if taken by pregnant women. ### Serious Side Effects - **Stevens-Johnson Syndrome (SJS)**: A rare but serious disorder causing flu-like symptoms, followed by a painful rash and blisters. Seek emergency medical help if you suspect SJS. - **Blood Disorders**: Some antibiotics can cause changes in blood cells, leading to increased infections or bleeding. Inform your doctor if you have a weakened immune system. - **Heart Problems**: Certain antibiotics can cause irregular heartbeats or low blood pressure. Notify your doctor if you have an existing heart condition. - **Tendonitis**: Inflammation or rupture of tendons can occur, especially with antibiotics like ciprofloxacin. People over 60 or those on corticosteroids are at higher risk. - **Seizures**: Rare but possible, especially with antibiotics like ciprofloxacin and cephalosporins. Inform your doctor if you have a history of seizures. ### Conclusion Always complete your prescribed course of antibiotics, even if you feel better. Stopping early can cause the infection to return stronger and more resistant. Consult your doctor if you experience severe side effects or have concerns about your medication.
