When you have an illness like a fever or a cough, when you go to the doctor, they give you different types of antibiotics, right? Sometimes you may not be very familiar with these medicines. Well, a very important class of antibiotics that doctors often recommend is called Macrolides. So today, let's talk about this simply, in a way that you can understand.
Simply put, what are these macrolides?
Macrolides are a class of antibiotics that are used to treat infections caused by bacteria . Their main function is to stop the growth, or spread, of bacteria that have entered our bodies.
It is important to remember that these medications only work for bacterial infections. They will not help with viral infections, such as the common cold or flu.
Your doctor may recommend a macrolide if they feel it is the best treatment for your infection. Also, some people are allergic to other antibiotics, such as penicillin. Macrolides are used as an alternative in such cases.
What are the most commonly used macrolides?
There are several types of macrolides that are commonly used by doctors in Sri Lanka and around the world. Let's take a look at them in the table below.
| Drug Name | A brief introduction |
|---|---|
| Azithromycin | A very common type of course that can be completed in a short period of time, such as three to five days. |
| Clarithromycin | It is also used for respiratory infections and some stomach ulcers. |
| Erythromycin | A somewhat old, but still very effective medicine used for various infections. |
| Fidaxomicin | It is used especially for C. diff infection, a severe intestinal infection. |
What diseases are macrolides used for?
These medications are used to treat a wide range of bacterial infections, from respiratory infections to sexually transmitted diseases.
- "Walking pneumonia" (Atypical pneumonia): A pneumonia condition that is slightly different from normal pneumonia and is not as severe.
- Bacterial eye infections: Infections that cause red, itchy eyes.
- Cat scratch fever
- Diphtheria
- H. pylori infection, which causes stomach ulcers: This is given in combination with other medications.
- Sexually transmitted infections: For example, conditions like Chlamydia.
- Throat infections (Strep throat): Especially for those allergic to penicillin.
- Severe diarrheal conditions: When traveler's diarrhea becomes severe.
- Urinary tract infection (Urethritis)
- Whooping cough (Pertussis)
In addition, sometimes a macrolide called `Erythromycin` is applied to the skin in the form of a gel to treat acne. The reason for this is that some types of bacteria on our skin contribute to the formation of acne. This gel controls those bacteria.
How should I use this medicine?
Macrolide antibiotics come in different forms.
- Types of pills to swallow
- Types of irrigation fluids
- Gel or lotion applied to the skin
- Ointments applied to the inner membrane of the eye
- Vaccines given by a doctor
The most important thing is to take the medicine exactly as your doctor tells you, in the right dose, at the right time, and for the right number of days. Read the instructions on the medicine label carefully. If you are not sure, ask your doctor.
If you have been prescribed a liquid medicine, use only the measuring cup or spoon that comes with it. Do not use household teaspoons or tablespoons, as they may not give you the correct dose.
The importance of completing the course of medicine
No matter how many days the doctor has prescribed you, you should take the medicine exactly for that number of days. You may feel better after two or three days of taking the medicine. But don't stop taking the medicine just because you feel better. If you stop, the remaining bacteria in your body will not be completely destroyed. After a while, the bacteria will become stronger again, and the disease may recur.
Are there any side effects?
Yes, like any medicine, macrolides can cause minor side effects. But don't worry, most of these are usually not serious. The most common side effects are stomach upset.
- Nausea and vomiting
- Stomach ache or pain
- Diarrhea
The chance of these side effects may vary depending on the type of macrolide you are given. Your doctor will explain this to you.
Another important thing is that these medications can interact with other medications you are taking. So, be sure to tell your doctor about all the medications you are taking (including vitamins and supplements). Also, if you drink alcohol, tell him/her about it. You may be advised to avoid alcohol while taking this medication.
Rarely, allergic reactions may occur. The most common symptom is a skin rash. Very rarely, severe skin conditions such as Stevens-Johnson syndrome may occur.
Can this medicine affect heart rhythm?
This is also very rare, but it is important to be aware of. Some macrolides can cause changes in the electrical activity of the heart (QT interval prolongation). This can lead to a very small risk of developing abnormal heart rhythms (arrhythmias).
But don't worry about this either. Doctors know about this. If you have a heart rhythm disorder like ``Long QT syndrome'', your doctor will give you a safer antibiotic instead of this medication.
When should I see a doctor?
It is very important to talk to your doctor in the following situations.
| Situation | What to do |
|---|---|
| If you have questions about how to take your medication. | Talk to the doctor and find out exactly. |
| If you have difficulty taking medication due to side effects (e.g. vomiting). | Do not stop taking the medication, but call your doctor for advice. |
| If the symptoms are still present after the course of medication is finished. | See the doctor again. |
| If you develop skin irritation or allergy symptoms. | Notify the doctor immediately. |
| Situations when you need to go to the ETU (Emergency Treatment Unit) urgently | |
| If you have watery diarrhea several times a day or if you are showing signs of dehydration (dry mouth, sunken eyes, decreased urination). | Go to the ETU of the nearest hospital immediately. |
| If you experience symptoms of a severe allergic reaction (Anaphylaxis), such as difficulty breathing and swelling of the face and lips. | This is an emergency. Go to the ETU immediately. |
Is Clindamycin also a Macrolide?
No. `Clindamycin` is not a macrolide. It belongs to another class of antibiotics called `Lincosamides`. However, that drug also stops the growth of bacteria in the same way as macrolides.
In conclusion, macrolides are a powerful weapon in the fight against bacterial infections. But this weapon should only be used strictly, and only under the advice of a doctor.
Take-Home Message
- Macrolides are a type of antibiotic that is only used to treat bacterial infections . They do not treat viral infections like the common cold.
- Be sure to inform your doctor about other medications you are taking, allergies you have, and other medical conditions (especially heart disease).
- Even if your symptoms subside, finish the full course of medication prescribed by your doctor. Stopping halfway may cause the disease to return, and become more severe.
- Seek immediate medical attention if you experience any serious side effects, such as severe diarrhea, severe skin rash, or difficulty breathing.
