What Type of Medicine Is This?
Simply put, this medicine makes the dark center of your eye, known as the pupil, grow larger. This process is called pupil dilation. The solution combines two active medicines: hydroxyamphetamine and tropicamide. Both work together to relax the tiny muscles inside your eye for a short time.
Imagine trying to look inside a dark room through a tiny keyhole compared to opening the door wide open. Opening the door lets you see everything inside clearly. Dilating your pupils lets your doctor examine your nerves, blood vessels, retina, and other delicate parts of your eye to spot any health issues early. This combination medicine is often known by the brand name Paremyd.
Things to Tell Your Doctor Before Using This Medicine
Before your doctor gives you these eye drops, they will ask about your overall health. However, you must always speak up if you have any of the following health conditions:
- Diabetes: Tell your doctor if you have diabetes or high blood sugar levels.
- Glaucoma: Mention if you have glaucoma or increased pressure inside your eye.
- Heart Disease: Inform your doctor about any heart conditions or circulation problems.
- High Blood Pressure: Let your doctor know if you take medicine for high blood pressure.
- Irregular Heartbeat: Report any history of an irregular heartbeat or palpitations.
- Thyroid Disease: Share if you have thyroid gland problems or hormone imbalances.
- Allergies: Tell your doctor if you are allergic to this medicine, other drugs, foods, dyes, or preservatives.
- Pregnancy: Inform your doctor if you are pregnant or planning to become pregnant.
- Breastfeeding: Let your doctor know if you are currently breastfeeding your baby.
Sharing these details with your doctor keeps you safe. Your medical history helps your healthcare team decide if this eye drop is the right and safe choice for you.
How Is This Medicine Used?
Most of the time, a doctor or trained clinic nurse will put these drops into your eyes during your visit. This medicine is designed strictly for use in the eyes. If a doctor ever prescribes these drops for home use, you must follow their exact instructions carefully.
Follow these steps if you ever need to apply the drops at home:
- First, wash your hands thoroughly with soap and warm water.
- Shake the medicine bottle gently before use.
- Tilt your head back slightly and pull your lower eyelid down gently with your index finger to create a small pocket.
- Be very careful not to touch the tip of the bottle against your eye, fingers, or any other surface. This prevents germs from entering the bottle.
- Place the exact number of drops prescribed by your doctor into the pocket of your lower eyelid.
- Close your eyes gently for a moment to let the medicine spread across your entire eye surface.
- Wash your hands again with soap and water after finishing.
What to Do in Case of Overdosage
Overdosing rarely happens because medical professionals usually give these drops in a clinic. However, if you use too many drops by mistake at home, you should contact your local emergency services right away or go to the nearest hospital emergency room (ER) right away.
Important Precautions While Using This Medicine
You need to keep a few important safety precautions in mind while using these eye drops:
- Blurry Vision and Light Sensitivity: Your vision will stay blurry for a few hours after the drops go in. Bright sunlight and indoor lights will also feel very uncomfortable. Wearing a good pair of sunglasses is essential to protect your eyes and reduce discomfort outdoors.
- Avoid Driving: Because your vision remains blurry and sensitive, do not drive cars, operate heavy machinery, or do tasks that require sharp focus until the medicine wears off completely.
- Dizziness and Drowsiness: Some people may feel a bit sleepy or dizzy. Older adults should stand up slowly from a bed or chair to prevent sudden dizziness and avoid accidental falls.
- Contact Lenses: If you wear contact lenses, take them out before receiving the drops. Ask your eye doctor when it is safe to put your contact lenses back in.
- Dry Mouth: You might notice your mouth feels dry. Chewing sugar-free gum, sucking on sugar-free hard candies, and drinking plenty of water can help relieve this feeling. Tell your doctor if dry mouth bothers you for a long time.
