About antibiotics
Antibiotics are medications designed to treat infections caused by bacteria. Sometimes called antibacterials, they refer to any medication that can effectively kill bacteria or stop the bacteria from reproducing, thus treating conditions caused by bacteria. They can sometimes be prescribed to prevent bacterial infections as well. There are seven types of prescription antibiotics.
What antibiotics treat
Antibiotics are used to treat or prevent infections caused by bacteria. It is sometimes difficult to determine if the infection is caused by a bacteria or a virus because symptoms for both infections may be similar.
Doctors will assess the situation and conduct the necessary examinations to determine the best course of action for the particular infection. This may require a blood or urine test.
Some common bacterial infections that can be treated with antibiotics are:
-
Bacterial pneumonia
As noted earlier, antibiotics are not effective against infections caused by viruses (i.e cold and flu).
Types of antibiotics available online
The strongest antibiotic for bacterial infections is a prescription-strength option. There are several types of antibiotic medications, each used to treat different bacterial infections. It’s important to discuss your history of allergies or intolerances of any antibiotics so that your doctor can safely prescribe what is needed and determine the most effective choice for your infection.
Penicillins
Cephalosporins
Macrolides
Tetracyclines
Others
How antibiotics work
The antibiotics you are prescribed will depend on the type of bacteria causing the infection.
Antibiotics use a variety of different mechanisms to eliminate or neutralize bacteria, but they generally work by:
-
Directly killing bacteria by weakening their cell walls until they burst and die
-
Inhibiting vital process that allow bacteria to grow and spread new cells
-
Hampering a bacteria’s ability to repair any damage to its DNA, such that it dies
When taken as prescribed, antibiotics are generally well tolerated. They can, however, still cause some side effects.
Different antibiotics will have different side effects. Generally, the most common side effects of antibiotics include
-
Abdominal pain and discomfort
-
Vomiting
-
Dizziness
-
Photosensitivity (more common with tetracyclines)
-
Fungal infections: Because antibiotics kill off protective bacteria in your body, they can allow certain fungal infections to form, including thrush and vaginal yeast infections.
Speak to one of our convenient online doctors about treatment if you develop these symptoms.
In rare cases, antibiotics may cause serious side effects, including those of a severe allergic reaction. These symptoms include:
-
A fast heartbeat
-
Wheezing
-
Difficulty breathing
-
Feeling lightheaded or faint
If you experience any of these side effects or other life-threatening symptoms, seek emergency medical attention immediately.
One of the main reasons to avoid overusing or misusing antibiotics is that doing so can lead to something called “antibiotic resistance” across the globe.1 Bacteria can replicate at an alarming rate when you have an infection, sometimes as quickly as every five minutes! These bacteria evolve over time because some of them replicate with mistakes, which allow the bacteria to fight off an antibiotic. These bacteria survive and then multiply with that new ability.
It’s important to only take antibiotics when you have a bacterial infection. Your doctor can help guide you in making a decision on whether or not an antibiotic is right for you.
The following conditions and substances may interfere with the efficacy of antibiotics or cause further complications:
-
Alcohol
-
Grapefruit juice
-
Excess calcium, sugars, or yeasts
-
Being pregnant or breastfeeding
Many antibiotics are safe for pregnant women, but some can be harmful, so tell your doctor if you're pregnant.
Some antibiotics may affect the effectiveness of other medications you are taking. For example, the antibiotic rifampin can affect the birth control pill's effectiveness. This is the only antibiotic known to reduce the effect of birth control pills, usually prescribed for tuberculosis. Aside from rifampin, you should not have any problems taking an antibiotic while on birth control.
Antibiotics risks
One of the main risks of taking antibiotics is developing antibiotic resistance. This can occur if you don't complete the full course of antibiotics prescribed to you.
Tell your doctor if you're pregnant. There are many antibiotics that are safe for pregnant women, but some can be harmful.
Antibiotics drug interactions
Some antibiotics may affect the effectiveness of other medications you are taking. For example, the antibiotic rifampin can affect the effectiveness of the birth control pill.

How should I take antibiotics?
Take antibiotics as prescribed by your doctor. The length of antibiotic treatment and the dosage will depend on your infection type. Based on your type of infection, antibiotics may be prescribed between 3 to 14 days. Complete the course of antibiotics as instructed to avoid a lingering infection. Antibiotics may be taken with food to avoid an upset stomach.
Can a pharmacist give you antibiotics or do I need a prescription?
Do antibiotics make you tired?
If you get a prescription for antibiotics, you may feel tired and/or fatigued after taking them. This may be a symptom of whatever infection is being treated by the antibiotics or a significant but rare side-effect of the antibiotic itself.
Luckily, tiredness is not a common side effect of most antibiotics. Some antibiotics are more likely to cause fatigue than others, including:
-
Azithromycin (Zithromax, Z-Pak)
-
Ciprofloxacin (Cipro, Proquin)
-
Amoxicillin (Amoxil)
How long does it take for antibiotics to work?
Antibiotics begin working as soon as you take them; relief begins within one to three days, but you should continue to take them for the duration as instructed by your doctor so they can fully fight off your infection.
Generally, you should start to feel better within 48 hours. If your symptoms worsen or do not improve by 48 hours, you should see the doctor for a follow-up appointment to discuss next steps. Be sure to follow your doctor’s advice, as some infections require in-person care if symptoms worsen at any time. Your doctor will be able to provide you clear instructions as to what to watch out for.
Can you be allergic to antibiotics?
Allergic reactions can happen with antibiotics and any medication. Allergic reactions to antibiotics can be mild, but some can be very serious and require immediate medical attention.
If you are allergic to a certain antibiotic, you will react to it almost immediately after administration. Symptoms can vary in type and severity, from a rash (hives), to trouble breathing, and swelling in the tongue and throat. If you have a severe allergic reaction to an antibiotic, known as anaphylaxis, this can be life-threatening. If you develop these symptoms, you should seek in-person medical attention immediately.
Another type of allergic reaction that can occur with antibiotics is Stevens-Johnson syndrome. Stevens-Johnson syndrome is a severe illness affecting your mucus membranes and skin. Stevens-Johnson syndrome starts with flu-like symptoms, including sore throat and fever, and can progress to a painful rash that quickly spreads and causes blisters. The top layer of your skin shedding may follow this.
Other symptoms of Stevens-Johnson syndrome include:
-
Skin pain
-
Hives
-
Coughing
-
Swelling in your tongue or face
-
Pain in your throat and mouth
If you develop signs and symptoms of Stevens-Johnson syndrome, you should stop taking the antibiotic immediately and seek in-person medical advice straight away.
Can urgent care prescribe antibiotics?
Do I need antibiotics for a wound infection?
For most infected wounds, you should seek medical treatment. Wounds should look and feel better as time goes on. If a wound looks or feels worse, it is likely infected. Specific symptoms of wound infection include:
-
Skin around the wound is red or hot
-
Swelling
-
Oozing pus (a yellowish liquid)
-
Redness may spread to other areas, often in streaks
-
Aches, pains, or fever
-
Malaise
If you experience any severe symptoms of wound infection, you should seek immediate medical care since infections can become life-threatening if improperly treated.
Infected wounds that aren’t treated properly can worsen, leading to loss of limbs or even death. Potential complications from untreated wound infections include:
-
Cellulitis, an infection of deeper tissues that can travel through your blood
-
Sepsis, a severe and potentially life-threatening infection of the blood
-
Necrotizing fasciitis, also known as flesh-eating disease, which leaves large areas of skin painful and damaged
Our doctors frequently prescribe antibiotics for wound infections if deemed safe enough to do so over telemedicine, which can heal the infection quickly and help you avoid any serious complications.
