Cephalexin is used to treat bacterial infections.
Cephalexin is one of many cephalosporin antibiotics used to fight bacterial infections and prevent the growth of offending bacteria. Allergy to this drug is considered rare; however, people who are allergic to penicillin are more likely to have a cephalexin allergy. Typical signs of a cephalexin allergy include skin rash, hives, throat and facial swelling. More serious allergy signs include dizziness, difficulty breathing, and anaphylactic shock.
It is important to seek emergency medical attention if symptoms of anaphylaxis develop after taking cephalexin.
There are several common signs of a cephalexin allergy, and many are typical of most allergic drug reactions. Hives, itching, and a rash are common telltale signs of an allergic reaction to cephalexin. It is also common for the face, tongue, lips and throat to swell and as a result breathing problems can also occur. People who are allergic to penicillin may also have similar signs of a penicillin allergy and are more likely to have a more severe or acute allergic reaction to this drug.
Dizziness and lightheadedness are two possible signs of a cephalexin allergy.
An acute allergic reaction can occur almost immediately after taking the antibiotic. This type of allergic reaction is usually more severe and carries a higher risk of anaphylactic shock or even death. Typical signs of an acute allergic reaction include the same reactions as a standard cephalexin allergy, as well as congestion, extreme difficulty breathing, reduced blood pressure and pulse, lightheadedness, and lightheadedness. It is normal for these reactions to quickly worsen without immediate medical attention.
Cephalexin is an antibiotic commonly prescribed to treat urinary tract infections.
Signs of a standard cephalexin allergy can occur over a wide range of time. Reports indicate that it may appear within 24 to 48 hours of initial dosing, but may take up to 10 days after initial dosing. There have also been reports of allergic reactions that did not appear until a full course of medication had been administered. Typically, symptoms can disappear over time without medical intervention. It can take a few days or even a week for some symptoms, such as hives or a rash, to go away completely. A healthcare professional will typically discuss courses of action for dealing with allergy symptoms.
Warning signs of an allergic reaction can include swelling of the tongue.
While not all allergy signs can be serious, it is highly recommended that a healthcare professional be contacted as soon as an allergic reaction is suspected, as symptoms can worsen over time without medical assistance. This is especially true for pediatric patients who are using cephalexin. Many doctors may recommend waiting for medical advice before taking over-the-counter allergy medications to help relieve allergy symptoms.
