Allegra's typical side effects include:
Contact your doctor if you experience any of these side effects. Anaphylaxis and angioedema are just two of the serious side effects that Allegra can produce. A potentially fatal allergic reaction called anaphylaxis can make breathing difficult, cause throat swelling, and result in low blood pressure. Swelling of the face, lips, tongue, or throat is a symptom of the serious condition angioedema. You should get medical help right away if you encounter either of these side effects.
Adults and children 12 years of age and older should take 60 mg twice daily or 180 mg once daily of Allegra. Children 6 to 11 years old should take 30 mg of Allegra twice daily. It's best to take Allegra with water.
It is crucial to inform your doctor or pharmacist about all the medications you are taking, including OTC medicines and dietary supplements, as Allegra can interact with other drugs. Fruit juices and sodas should not be consumed while taking Allegra. You should avoid exposure to the sun and wear sunscreen when you are outside because Allegra can make you more sensitive to sunlight.
