Doxycycline Side Effects

Here Are Common Doxycycline Side Effects

Doxycycline is a broad-spectrum antibiotic that belongs to the class of tetracycline antibiotics. It is used to treat a wide range of bacterial infections, including urinary tract infections, acne, and respiratory infections, among others. However, like any other medication, there are known side effects associated with the use of doxycycline. This article explores some of the common doxycycline side effects, their causes, and possible management options.

Gastrointestinal symptoms

Gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhea are some of the most common side effects of doxycycline. These symptoms occur because doxycycline irritates the lining of the gastrointestinal tract, leading to inflammation, damage, and reduced absorption of nutrients from food.

To reduce the severity of gastrointestinal symptoms, doxycycline should be taken with plenty of water. Additionally, taking doxycycline with food can help reduce nausea, vomiting, and abdominal pain. If symptoms persist, medical attention should be sought.

Skin reactions

Doxycycline can cause skin reactions, such as rashes, hives, and photosensitivity. Photosensitivity is a condition where the skin becomes overly sensitive to sunlight, leading to redness, itching, and burning sensations.

To avoid skin reactions, patients using doxycycline should avoid excessive exposure to sunlight or use protective clothing. Additionally, if a rash or hives appear, medical attention should be sought.

Tooth discoloration

Doxycycline can cause permanent discoloration of teeth in children younger than eight years. It can also cause temporary teeth discoloration in adults and children. This side effect occurs because doxycycline binds with calcium ions in the teeth, leading to yellow or grayish discoloration.

To avoid teeth discoloration, children under eight years should use alternative antibiotics. Additionally, patients using doxycycline should avoid taking it with dairy products or calcium supplements.

Liver and kidney damage

Doxycycline can cause liver and kidney damage, although it is a rare side effect. The liver and kidneys play a critical role in clearing medicines from the body, and when they are damaged, the body can retain harmful toxins.

To reduce the risk of liver and kidney damage, patients using doxycycline should undergo regular blood tests to assess their liver and kidney functions. Additionally, if symptoms such as dark urine or jaundice occur, medical attention should be sought immediately.


Doxycycline can cause yeast infections, also known as candidiasis. This side effect occurs when doxycycline alters the balance of microorganisms in the gut, leading to an overgrowth of yeast.

To avoid candidiasis, patients using doxycycline should take probiotics to improve gut health. Additionally, if symptoms such as itching, redness, and white discharge occur, medical attention should be sought.


So doxycycline side effects – In conclusion, doxycycline is a broad-spectrum antibiotic used to treat bacterial infections. However, it has some side effects, some of which are common, while others are rare. The common side effects include gastrointestinal symptoms, skin reactions, tooth discoloration, yeast infections, and liver and kidney damage. Patients using doxycycline should be aware of these side effects and know the measures they can take to manage them. If any of the symptoms persist or worsen, medical attention should be sought immediately.
