Are your eyes red and itchy? You might also need this eye medicine - let's learn about Azelastine!

Do you also wake up in the morning with red, itchy eyes? Or do you constantly sneeze and watery eyes when you touch dust or go near certain flowers? Eye problems caused by allergies like these are not uncommon. But there is nothing to worry about, there are good treatments for this. That is what we are going to talk about today.

What kind of medicine is Azelastine?

Simply put, Azelastine is an eye drop that is used to control the symptoms of allergies in your eyes. It is used to treat things like red, itchy eyes. Imagine, when our body has an allergy, a chemical called histamine is released. That histamine is what causes the itching and redness. This Azelastine medicine belongs to the group of medicines called antihistamines . That is, this medicine blocks the action of histamine. Then those annoying symptoms gradually decrease. Do you understand?

You can usually buy this medicine from pharmacies under brand names like Optivar , but it's best to only take it if it's prescribed by a doctor.

This medicine may sometimes be used by doctors for other purposes, so if you have any questions, it's best to ask your doctor or pharmacist.

What are the things I need to tell the doctor before using this medicine?

This is very important. Before you use Azelastine eye solution, it is important to tell your doctor or healthcare provider:

  • If you wear contact lenses: Sometimes contact lens wearers need to follow special instructions when using this medication, so it is important to inform your doctor about this.
  • If you have ever had an unusual allergic reaction to azelastine, any other medicine, food, dye, or preservative: This is a must-mention. This medicine may not be suitable for you.
  • If you are pregnant or planning to become pregnant: It is very important to tell your doctor about this, as you need to be very careful about the medications you use during pregnancy.
  • If you are a breastfeeding mother: Some medications can pass to your baby through breast milk, so you should talk to your doctor about this as well.

When you tell your doctor these things, he or she can give you precise advice on whether this medication is right for you or not, and how to use it safely.

Okay, now let's see how to apply this medicine to the eyes?

This medicine is for eye use only . It is not recommended to take it by mouth. You should follow the instructions on the prescription label given to you by your doctor exactly. Now let's see how to do it step by step:

1. Wash your hands thoroughly: Wash your hands thoroughly with soap and water before and after applying the medicine. This is very important, otherwise germs can get into your eyes.

2. Tilt your head back slightly: While sitting in a chair or lying down in bed, tilt your head back slightly.

3. Pull down the lower eyelid: With your index finger, pull down the lower eyelid to create a small pouch. This is where you will put the eye drops.

4. Do not touch the tip of the dropper to your eyes, fingertips, or anywhere else: This is also very important. If the tip of the dropper touches anything, it will become dirty and germs can get into the medicine bottle.

5. Put the recommended number of drops of medicine (usually 1 drop) into the bag: Do not put more than the doctor tells you to.

6. Close your eyes: After applying the medication, close your eyes and wait for a while. Do not blink suddenly. Doing so may cause the medication to leak out.

Take your doses at the right times, at the right intervals. Do not take more or more often than your doctor tells you to.

What if you use other eye medications?

Imagine that your doctor has prescribed another eye medication along with Azelastine. In that case, you should wait at least 10 minutes after applying one medication before applying the other . If you are using an eye ointment, apply it last .

Only by using medicine in this orderly and clean manner can you achieve the best results.

What do I do if I miss my medication appointment?

If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose. Just take the next dose at the scheduled time. Do not take a double dose or extra doses to make up for a missed dose.

👩🏽‍⚕️ Additional questions (FAQs)

💬 What kind of antibiotic is Trimethoprim used for?

This is an antibiotic (like the one in Bactrim) that is used alone. Doctors primarily prescribe it to treat 'Urinary Tract Infections (UTI)' (urinary tract infections, difficulty urinating). In addition, it is also used very successfully for severe ear infections (Ear infections / Otitis media) and some respiratory problems in young children.

💬 How does this medicine kill the bacteria that cause urinary tract infections?

In order for bacteria to grow and multiply, they must produce folic acid within their bodies. When this Trimethoprim drug enters the body, it completely shuts down the bacteria's folic acid-making factory (enzyme). When folic acid is lost, the bacteria cannot make DNA and they simply die (bacteriostatic).

💬 What are the main side effects that can occur while taking this medicine?

Like other antibiotics, this can cause diarrhea, vomiting, and stomach pain. However, this medicine has a rare risk of bone marrow suppression. Also, if you develop a severe skin rash (especially in people with sulfa allergies), you should stop taking the medicine immediately and see a doctor!
