Allegra 120mg tablet is an antihistamine medication used to treat and manage allergies. This tablet relieves watery eyes, runny or blocked nose, itching, sneezing, and swelling. It also helps relieve skin allergy symptoms (hives), such as skin rash, itching, and swelling.
Allegra 120mg tablet contains fexofenadine as an active ingredient. Fexofenadine works by blocking the effects of histamine, a substance that causes allergy symptoms.
Take an Allegra 120mg tablet as advised by your doctor for the prescribed duration. You can take this medicine with or without food. It is advised to take this medication at the same time every day. Do not miss or skip the dose of Allegra.
A few other tablets with fexofenadine as their composition are Fxolife 120mg, Air 120, Fexy 120mg, and Fexova 120.
You may experience dizziness, drowsiness, and headache while taking this medication. However, these side effects are temporary and resolve on their own. If these side effects worsen, contact your doctor immediately.
To avoid getting an allergy, avoid exposure to the substance you're allergic to whenever possible. Allegra 120 should not be used by children under 12 years of age. Before starting treatment with Allegra 120mg tablets, inform your doctor about all your medications and medical conditions.

Precautions and Warnings
Alcohol
UNSAFENo, you should avoid drinking alcohol while on this medicine as it may make you feel sleepy and increase side effects.
Pregnancy
WITH CAUTIONAllegra 120 mg is generally considered relatively safe in pregnancy, but it should be taken only if your doctor recommends it. It may help with allergy-related itching, sneezing, or runny nose, and can ease mild allergy-triggered breathing discomfort, but it is not a treatment for asthma or serious breathing problems. Always check with your doctor before using it during pregnancy to be sure it is appropriate and safe for your condition.
Breastfeeding
WITH CAUTIONNo, Allegra 120mg Tablet passes into the breastmilk. Thus, it is recommended not to take this medicine while breastfeeding, unless advised by your doctor.
Driving
WITH CAUTIONAllegra 120mg Tablet does not have any effect on the ability to drive or use machines. However, caution is advised while driving or doing anything that requires concentration as it can cause dizziness and sleepiness.
Other General Warnings
- You are suffering from liver or kidney disease.
- You are suffering from any heart disease as this medicine is known to increase your heartbeat.
- You are an elderly person.
- Allegra 120mg Tablet should not be used by children below the age of 12.
Directions for use
Storage and disposal
- Store it in a cool dry place. Protect it from moisture and direct sunlight.
- Keep it away from children and pets.
Quick tips
- Take the medicine exactly as recommended regarding dose and duration. Do not exceed the prescribed amount, and keep it out of reach of children under 12 years of age.
- Use this medication for allergy symptoms like sneezing, runny nose, and itchy skin; it does not treat infections, the common cold, ringworm, or digestive conditions.
- Recognize that this provides supportive relief for itching from eczema or stings but is not a treatment for asthma or emergency peanut allergies.
- Use this for a sore throat or dry cough only when caused by allergies, as it will not treat these symptoms if they are due to an infection.
- Monitor for side effects and consult your doctor immediately if they occur. Also, never give this medication to pets unless a veterinarian specifically directs you to.
- Do not take it with fruit juice. Apple, orange, and grapefruit juice measurably reduce fexofenadine absorption, so take it with water.
- Fexofenadine is one of the least sedating antihistamines, but it still makes some people drowsy. See how it affects you before driving or operating machinery.
- It controls symptoms rather than curing the allergy. Identifying and reducing your trigger- dust mite, pollen, pet dander, mould- is what reduces how much medicine you need.
- For seasonal allergy, it works best taken regularly through the season rather than only on bad days.
- It relieves sneezing, itching, and a runny nose, but not a blocked nose as well. Tell your doctor if congestion is your main problem, as you may need a different treatment.
- Tell your doctor if you are pregnant, planning a pregnancy, or breastfeeding, and do not give an adult-strength tablet to a child.
