Doxycycline Side Effects

Doxycycline Side Effects

There are a few side effects of doxycycline. These include esophagitis, tooth discoloration, and nausea. The drug also causes upper abdominal pain. You should consult with a doctor if you are experiencing any of these symptoms. You should avoid taking doxycycline if you have kidney problems.


Doxycycline is a common antibiotic that can cause side effects in the esophagus. The medication inhibits the synthesis of proteins in the esophagus. As a result, the lining can become inflamed and ulcers may form. However, if these symptoms are experienced, discontinuation of the drug is usually enough to cure the problem.

Drug-induced esophagitis may result from various mechanisms, including antibiotics, non-steroidal anti-inflammatory drugs, and potassium chloride. Among these, doxycycline accounts for more than half of cases. Other etiological agents include bisphosphonates, ascorbic acid, potassium chloride, and ferrous sulfate.

upper abdominal pain

If you're taking doxycycline, you may experience upper abdominal pain. This condition is usually temporary and subsides within a day or two. To avoid this side effect, try to eat a little before taking your pill. You should also avoid lying down for 30 minutes after you take your doxycycline pill. In addition, don't drink citrus or carbonated drinks, as they may make the pain worse.

tooth discoloration

Doxycycline side effects include tooth discolouration. This is a common effect of this antibiotic. The discoloration occurs due to a change in the structure of the tooth's hard tissues. Examples of these discolorations are shown in Box 7.5. The discoloration in teeth can be brown, or mottling. It may also be yellow or grey.

This effect occurs in children who are taking Doxycycline monohydrate. The discoloration can affect the development of teeth. In children, doxycycline may cause teeth to become brittle and discolored. It may also affect the growth of the teeth. For this reason, it is recommended that pregnant women avoid doxycycline monohydrate while pregnant. Moreover, they should discuss the possible risk of tooth discoloration with their healthcare provider before starting this drug.


One of the most common side effects of doxycycline is nausea. The best way to deal with nausea while on doxycycline is to drink lots of water and eat bland foods as much as possible. Also, avoid food and beverages that have strong odors. Research shows that 8.1 percent of people taking doxycycline experience nausea. In addition to nausea, doxycycline can cause dehydration. You should drink plenty of water to replace lost fluids.

This common side effect usually subsides within a few days. If it persists, however, you should contact your doctor and take a different antibiotic. You may want to consider taking probiotics along with doxycycline. However, it's important to take probiotics at a different time from the antibiotic.
