Doxycycline is a prescription antibiotic that is typically used to treat bacterial infections, although it may also have other uses, such as preventing malaria. As is the case with any medication, there are some possible side effects associated with the use of doxycycline. Most patients do not experience severe side effects, although any new symptoms that develop after beginning this medication should be reported to a doctor for further evaluation. Common side effects of doxycycline may include sore mouth, genital itching, or diarrhea. Some patients may also experience blurred vision, stomach pain, or confusion.
Stomach and digestive issues are among the most commonly reported side effects of doxycycline. Diarrhea is commonly reported among patients taking this medication. Nausea, loss of appetite, and vomiting are also frequently reported. Some patients may also experience stomach cramps or abdominal pain. These side effects typically disappear once the medication has been discontinued.
Many people also report itching while taking doxycycline. This itching may occur anywhere on the body, but is most common in the rectal or vaginal area. These side effects are generally mild and do not mean the patient should stop taking the medication. If the itching is accompanied by a rash or hives or if facial swelling and difficulty breathing develop, this could indicate a possible severe allergic reaction. This is a medical emergency, and medical attention should be sought immediately.
Headaches or blurred vision may occur as side effects of doxycycline. Over-the-counter pain relievers may help with the headaches. If either of these symptoms becomes severe or if they are accompanied by severe vomiting, a doctor should be consulted right away. Mild to moderate confusion may also occur as a result of taking this medication. Extreme fatigue or muscle weakness may also be associated with the use of doxycycline.
Dark urine or light-colored stools sometimes develop as side effects of doxycycline usage. Some patients may also notice a decreased amount of urine volume while taking this medication. These side effects are not usually serious, although in some cases they may indicate digestive or kidney problems. Any side effects that become bothersome should be reported to a doctor to make sure there are no severe complications. While severe complications are rare, it is always best to be evaluated as soon as possible to make sure that this is the appropriate medication for the individual at hand.
