What Should You Not Do While On Antibiotics?

4 min read

According to the CDC, approximately one-third of antibiotic use is not needed or inappropriate, a major driver of the growing problem of antibiotic resistance. It is essential to know what you should not do while on antibiotics to ensure effective treatment and minimize potential harm.

Quick Summary

Taking antibiotics correctly is crucial for full recovery and preventing resistance. Certain activities, foods, and other medications can interfere with effectiveness or increase side effects. Key actions to avoid include stopping the course early, drinking alcohol, consuming dairy products with specific medications, and mixing with certain other drugs. Following proper guidelines protects your health and helps preserve antibiotic effectiveness for the future.

Key Points

  • Do not stop taking antibiotics early: Finishing the full course is essential to kill all bacteria and prevent drug resistance.

  • Avoid alcohol: Combining alcohol with certain antibiotics, like metronidazole, can cause severe reactions and hinder your body's healing process.

  • Be mindful of food interactions: Dairy products, calcium supplements, and acidic foods can interfere with the absorption of some antibiotics.

  • Do not take medication without a prescription: Using leftover or someone else's antibiotics is dangerous and contributes to widespread resistance.

  • Protect yourself from the sun: Certain antibiotics can increase your skin's sensitivity to sunlight, leading to easy sunburns or rashes.

  • Consult your doctor about other medications: Some antibiotics can interact with other drugs, including birth control and blood thinners, reducing effectiveness or causing complications.

  • Take probiotics at a different time: To avoid the antibiotic killing beneficial gut bacteria, space out your probiotic dose by at least two hours.

Antibiotics are powerful tools used to treat bacterial infections, but their misuse and misuse have contributed to the serious public health threat of antibiotic resistance. To ensure you recover fully and safely, it's vital to know the critical mistakes to avoid during your treatment course.

The Dangers of Incomplete or Misguided Use

Do not stop taking antibiotics early

Even if you start feeling better after a few days, it is crucial to complete the entire course of antibiotics as prescribed. The reason you feel better is that the antibiotic has killed the most vulnerable bacteria, but some tougher, more stubborn bacteria may still be present. If you stop early, these remaining bacteria can multiply, and may develop resistance to the antibiotic, making future infections harder to treat. A relapse can also occur, sometimes worse than the original infection.

Do not use someone else's prescription

Using leftover antibiotics or taking someone else's medication is extremely dangerous. An antibiotic is chosen for a specific type of bacterial infection, and taking the wrong one for your illness is ineffective and contributes to resistance. It can also delay proper treatment and cause unnecessary side effects. Always consult a healthcare provider for a correct diagnosis and prescription.

Do not use antibiotics for viral infections

Antibiotics are only effective against bacterial infections and have no effect on viruses, which cause illnesses like the common cold, flu, and most sore throats. Taking antibiotics for a viral illness is not only ineffective but can also cause unnecessary and potentially harmful side effects, while promoting antibiotic resistance.

Potential Interactions with Food, Drink, and Other Medications

Do not drink alcohol

While it's a common misconception that alcohol is safe with most antibiotics, it is best to avoid it completely while recovering from an infection. Alcohol can weaken your immune system, dehydrate you, and hinder the healing process. For certain antibiotics, such as metronidazole and tinidazole, mixing with alcohol can cause a severe reaction with symptoms like nausea, vomiting, headaches, and flushing. Your doctor or pharmacist can advise you on how long to wait after finishing a course before consuming alcohol again.

Do not take with dairy or calcium supplements

Dairy products like milk, cheese, and yogurt can interfere with the body's ability to absorb certain antibiotics, including tetracyclines and fluoroquinolones. Calcium binds to the medication, preventing it from working properly. To prevent this, wait at least three hours after taking your antibiotic before consuming dairy. Mineral-containing supplements and antacids can have a similar effect.

Do not take with high-fiber or acidic foods

High-fiber foods: Eating high-fiber foods such as beans, lentils, and whole grains can slow down the absorption of your medication. It's best to consume these in moderation and at a different time from your antibiotic dose. Acidic foods: Citrus fruits, juices, tomatoes, and chocolate can also decrease the absorption of certain antibiotics, like penicillin. Stick to water when taking your medication.

Do not mix with other medications and supplements

Tell your healthcare provider about all medications, vitamins, and herbal remedies you are taking, as some can interact negatively with antibiotics. Examples include:

  • Blood Thinners (like Warfarin): Some antibiotics, like metronidazole, clarithromycin, and trimethoprim-sulfamethoxazole, can increase the effects of warfarin, raising the risk of bleeding.
  • Antacids and Supplements: Minerals like calcium, magnesium, aluminum, iron, and zinc can bind to and prevent the absorption of certain antibiotics. Space them out by several hours.
  • Oral Contraceptives: Some antibiotics can make birth control pills less effective, requiring additional contraception to be used.

Important Considerations for a Smooth Recovery

Do not ignore potential side effects

While some side effects like mild stomach upset, nausea, or diarrhea are common, you should not ignore them. Your doctor can offer advice on managing symptoms, such as taking the antibiotic with food (if allowed) or using probiotics at a different time. Severe reactions, including a rash, hives, swelling, or difficulty breathing, require immediate medical attention as they could be an allergic reaction.

Do not get excessive sun exposure

Certain antibiotics, including tetracyclines and fluoroquinolones, can cause photosensitivity, making your skin more susceptible to sunburn and rashes. Limit your time outdoors, wear protective clothing, and use sunscreen during your treatment.

Side Effects Comparison: Common vs. Severe

Side Effect Type Common Examples Management Tips When to Seek Medical Help
Common Stomach upset, nausea, diarrhea, vomiting Take with food (if directed); Use probiotics spaced out from antibiotic dose If symptoms are severe or persistent
Fungal Overgrowth Yeast infections (oral thrush, vaginal yeast infection) Consult a doctor for appropriate treatment; taking probiotics may help If symptoms appear
Photosensitivity Increased risk of sunburn and rashes Avoid direct sunlight, use sunscreen, and wear protective clothing If a severe rash or sunburn occurs
Severe Allergic Hives, swelling of face/tongue, difficulty breathing Immediate medical attention required (call 911) Immediately
Severe Intestinal C. difficile infection (severe diarrhea, abdominal pain, fever) Contact your healthcare provider immediately Immediately

Conclusion: Responsible Use is the Best Course of Action

Using antibiotics responsibly is the single most important action you can take to ensure a successful recovery and help fight the global crisis of antibiotic resistance. Always follow your doctor's instructions exactly, complete the entire course of medication, and be aware of potential interactions with food, alcohol, and other drugs. If you have any questions or concerns, especially about potential drug interactions or severe side effects, don't hesitate to contact your pharmacist or healthcare provider. Understanding these precautions empowers you to protect your health and the health of your community.
