Antibiotics are medications designed to combat bacterial infections in the body. They either kill bacteria or impede their growth, aiding the body’s immune system in overcoming the infection. It’s crucial to note that antibiotics are ineffective against viral infections like the flu or common cold.
Precautions to take while using antibiotics:
1. Follow Doctor’s Instructions: Take antibiotics precisely as prescribed, completing the full course even if symptoms improve. This prevents the survival of bacteria, reducing the risk of antibiotic resistance.
2. Adhere to Dosage and Timing: Stick to the prescribed dosage and schedule. Missing doses or stopping treatment prematurely may result in incomplete eradication of bacteria.
3. Avoid Alcohol: Alcohol can interact with certain antibiotics or intensify side effects. It’s advisable to abstain from alcohol while undergoing antibiotic treatment.
4. Be Mindful of Food Interactions: Some antibiotics might interact with specific foods, so consult the doctor or pharmacist about any dietary restrictions.
5. Monitor Side Effects: Be vigilant about potential side effects like diarrhea, nausea, or allergic reactions. Contact the doctor if severe side effects occur.
6. Avoid Sharing or Storing Old Antibiotics: Never share antibiotics or use leftover medication from previous treatments. Only use antibiotics prescribed for the current infection.
7. Consider Probiotics: Antibiotics may disrupt the natural balance of beneficial gut bacteria. Incorporating probiotics (like yogurt or supplements) can help restore this balance and prevent digestive issues.
8. Inform Healthcare Providers: Notify healthcare providers about other medications or supplements being taken to prevent potential interactions.
9. Allergy Awareness: Individuals allergic to specific antibiotics should inform healthcare providers to prevent severe allergic reactions.
Adhering to these precautions ensures the effectiveness of antibiotics, reduces the risk of bacterial resistance, and minimizes the likelihood of adverse effects. Seeking medical advice before antibiotic use and following prescribed instructions diligently is crucial for safe and effective treatment.
The medicines that kill or stop the growth of the disease – causing microorganisms are called antibiotics.
For example: Streptomycin, tetracycline, etc.
Following precautions must be taken while taking antibiotics:
• Antibiotics should be taken only on the advice of a qualified doctor.
•One must finish the course prescribed by the doctor.
• Antibiotics must be avoided when not needed or in wrong doses.
