Common Side Effects of Antibiotics: Azithromycin, Doxycycline, and Amoxicillin

Antibiotics are usually prescribed to cure sore throats and urinary tract infections. They are essential drugs, but that does not mean that side effects do not occur. We all respond in different ways to those drugs, and knowing how to react to normal reactions will make you more able and ready to manage your treatment process.

Suppose you are new to antibiotics or new to taking them. In that case, this article covers the most well-documented side effects of three of the most commonly prescribed medications: azithromycin, doxycycline, and amoxicillin.

Azithromycin: Most Prescribed, Rapid-Acting

Azithromycin is often chosen for respiratory illnesses, ear infections, and certain sexually transmitted diseases. Since it is so convenient to dose, at times as brief as three to five days, it is administered to all ages.

Sufferers of azithromycin 500mg experience mild or moderate side effects, the most common of which are nausea, stomach discomfort, and occasional diarrhea. Some others experience a difference in sense of taste, temporary weakness, or mild sun sensitivity.

Although commonly well tolerated, antibiotics like azithromycin have occasionally caused more gastrointestinal distress. This can be avoided by consuming an easy-to-digest diet and a beverage.

Doxycycline: Great but Sun-Sensitive

Doxycycline 100 mg is commonly administered for treating acne, malaria prophylaxis, and respiratory or urinary tract bacterial infections. It belongs to the tetracycline class of antibiotics and is very effective and practical.

However, the most reported side effect of doxycycline 100 mg is photosensitivity. Because their skin is more sensitive to the sun, buyers are advised to avoid sun exposure for a long time. These side effects are possible even if they do not have enough water while taking it: nausea, minor headaches, or throat irritation.

It must be consumed with plenty of water and in an upright position to prevent esophagitis. Like all antibiotics, it has a transient action on the gut flora, and for this reason, some people take probiotics while taking the medication or when they are not on the drug.

Amoxicillin: The Timeless First-Line Antibiotic

Amoxicillin 500 mg is among the best-selling antibiotics, especially for adults and children experiencing sinusitis, dental abscess, or ear infection. It is a penicillin antibiotic and also highly stomach-friendly to most consumers.

However, gastrointestinal disturbances, such as rash, diarrhea, or bloating, may occur with amoxicillin 500 mg in some patients. Separately, itching and hives may sometimes happen, though usually in people with known penicillin allergies.

Most people take it two to three times a day, and this method helps more and causes fewer problems.

General Principles of Antibiotic Side Effect Management

Although antibiotics are great medicines, they disrupt the natural balance between good and bad bacteria in the gut. As a result, bloating, cramps, and changes in bowel habits are some of the most common side effects.

Some of the other practical ways of avoiding these effects are as follows:

• Be sure to stay hydrated and have light meals while you are there.

• Avoid alcohol, which worsens side effects.

• Try to add yogurt or probiotic foods to your diet.

Keep taking the antibiotics, even if you feel good, so as not to encourage antibiotic resistance.

Because every person is unique, knowing when something feels unusual will let you judge whether a return visit to the doctor is needed.

Can I keep side effects from happening?

You can't prevent all side effects, but knowing your susceptibility, it might be to your advantage. For instance, if you have already taken azithromycin 500mg and have had stomach upset, you can request that your doctor modify the dosing schedule. Likewise, if you have acquired sunburn from taking doxycycline 100 mg, avoid the sun as much as you can and wear protective gear. Patients with a rash or swelling following the administration of amoxicillin 500 mg must be careful with other medications in the penicillin group and report it as a possible allergy. 

Conclusion

Antibiotics such as azithromycin 500mg, doxycycline 100 mg, and amoxicillin 500 mg have earned their reputation as a cure-all, but, like any other drugs, they do come with possible side effects. Being aware of what each of them does to your body—and how to prepare for or defend against them—can make recuperation less of a chore and more tolerable. For those patients requiring access to quality antibiotics in private and discreet delivery, ApotheekPlus provides an easy but reliable way of getting what you need, when you require it, with care and discretion at all times.
