Since Dexamethasone can be used in different forms, it can have different side effects. The use of dexamethasone eye drops is more typical to cause such adverse reactions as blurring of vision, persistent eye pain or redness, enlarged pupils, increased pressure in the eye, posterior subcapsular cataracts, continued or worsening itching or swelling, continuing blurred vision, eye discharge, glaucoma, and vision problems. The use of dexamethasone ear drops can cause ear irritation (burning, stinging and redness). Apart from the usual side effects (which also occur more frequently), dexamethasone solution often causes clumsiness, dizziness, facial hot flush, feeling of whirling motion, general body discomfort, pain, swelling, redness or hypoderm atrophy at the injection site, seizures, tendon or bone pain, vision changes or other eye problems. In addition, Dexamethasone solution can cause serious adverse reactions more often.
Like any other medicine, Dexamethasone can cause allergic reactions in the form of rash, hives, itching, breathing or swallowing difficulty, hoarseness, chest tightness , swelling of the face, eyes, mouth, lips, tongue, or throat. Dexamethasone can also cause severe anaphylactoid reaction, anaphylaxis, and angioedema. These reactions are serious and require immediate medical attention.
Dexamethasone intake can cause some changes in your blood tests. Therefore, if your doctor founds in your laboratory tests such changes as eosinopenia, lymphopenia, neutropenia, liver enzymes elevations (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, γ-glutamyl transpeptidase, and bilirubin), hypocoagulation, decreased glucose tolerance, hyperglycemia, hypocalcemia, hypernatremia (due to sodium retention), hypokalemia with hypokalemic alkalosis (due to potassium loss), glycosuria, blood in urine, increased or decreased motility and number of spermatozoa, you should keep in mind that these can be as a result of Dexamethasone use. However, these adverse reactions are usually reversible after the use of Dexamethasone has been discontinued.
Dexamethasone can cause some serious side effects that require urgent medical attention. Some of the side effects are:
When used during pregnancy, Dexamethasone can lead to slowed development of the fetus, and adrenocortical insufficiency after giving birth. Dexamethasone also passes into breast milk and so it must be used under your doctor’s supervision.
In addition to the common and serious side effects that can develop both in adults and in children, Dexamethasone can slow growth and cause development of the pseudotumor cerebri in little patients.
You may never experience any of the side effects listed above. Your doctor cannot predict your body’s reaction to Dexamethasone until you have tried it. That is why you should immediately inform your doctor of any changes in your health condition after taking Dexamethasone. Therefore, when you feel something is wrong, ask your doctor for advice and he or she will diagnose if your problem is connected with the medicine intake. You should also be careful because some of the side effects of Dexamethasone require urgent medical attention. In addition, it is strongly recommended not to stop Dexamethasone intake suddenly because this can lead to withdrawal syndrome.
