Hydroxyamphetamine and Tropicamide (Ophthalmic)

Overview

Available as a prescription medicine, Hydroxyamphetamine and Tropicamide is used before or during an eye examination and allows doctors to carry out specific diagnostic tests. In order to examine the eyes fully, the patient's pupils may need to be dilated. By administering Hydroxyamphetamine and Tropicamide eye drops, doctors can dilate, or widen, the patient's pupils and examine the eye more clearly.

With two active ingredients, Hydroxyamphetamine and Tropicamide is a combination medicine and is both anticholinergic and sympathomimetic. By inhibiting parasympathetic nerve impulses, the medication allows the muscles of the eye to relax. As a result, the pupils are able to widen enough for diagnostic testing to be carried out.

Once Hydroxyamphetamine and Tropicamide eye drops have been administered, patients may notice that their ability to see things at close range is affected. This is a normal side-effect of Hydroxyamphetamine and Tropicamide eye drops and occurs because the pupils are dilated. Once the effects of the eye drops have worn off, the patient's vision should return to normal.

Although Hydroxyamphetamine and Tropicamide eye drops can sometimes be used to treat specific eye conditions, they are predominantly used to facilitate diagnostic testing. As a relatively fast-acting medication, they allow thorough examinations to take place without the need for more invasive interventions.

Due to the risks associated with overdose, it's vital that patients obtain immediate medical assistance if they experience the above symptoms after Hydroxyamphetamine and Tropicamide has been administered.

Dosage

When Hydroxyamphetamine and Tropicamide eye drops are administered prior to an eye examination, patients are normally advised to apply just one or two drops to each eye. In most cases, Hydroxyamphetamine and Tropicamide will need to be applied fifteen minutes before the patient's assessment so that the medication has the chance to take effect.

In order to administer Hydroxyamphetamine and Tropicamide eye drops, patients should wash their hands and press gently on their lower eyelid. This will create a gap between their eye and lower eyelid and the Hydroxyamphetamine and Tropicamide eye drops can be administered into this space.

Once the appropriate dose of Hydroxyamphetamine and Tropicamide has been administered, patients should close their eye for approximately two to three minutes. During this time, patients should use their finger to gently press on the inner corner of the eye. This ensures that the medication is able to access the relevant parts of the eye.

Following the application, patients should wash their hands and place the cap on the container of medicine. When administering Hydroxyamphetamine and Tropicamide eye drops, patients should not let the applicator come into contact with any substances, including the eye itself. This helps to ensure that the applicator is free of germs and that the patient doesn't contract an eye infection.

Although this is the standard regime for the use of Hydroxyamphetamine and Tropicamide eye drops, every patient will be given specific instructions by their physician. Their dosage and treatment plan will be based on their individual needs so patients should always follow their doctor's advice when using Hydroxyamphetamine and Tropicamide eye drops.

If patients are unsure how to administer Hydroxyamphetamine and Tropicamide eye drops, they should seek help from their ophthalmologist or physician.

Potential Drug Interactions

As some medicines can interact with others, patients may not be prescribed Hydroxyamphetamine and Tropicamide eye drops if they are already using certain medicines. Hydroxyamphetamine and Tropicamide eye drops are not usually prescribed in conjunction with the following substances, for example:

  • Donepezil
  • Bupropion
  • Tiotropium
  • Oxymorphone

Although the above medications are not normally used alongside Hydroxyamphetamine and Tropicamide eye drops, physicians may feel it is appropriate in some cases. If so, patients may be given a modified dose of medication as this could help to reduce the risk of an interaction taking place.

Patients should be aware that interactions can also occur between over-the-counter medicines, supplements and vitamins. Due to this, patients should inform their doctor if they are taking any of these substances before using Hydroxyamphetamine and Tropicamide eye drops. Similarly, patients should seek medical advice before using any new medicines, supplements and/or vitamins once they have started to use Hydroxyamphetamine and Tropicamide eye drops.

Warnings

Before using this medicine, patients should discuss their current health and their medical history with their doctor. If patients are suffering with other health conditions, it may affect their use of Hydroxyamphetamine and Tropicamide eye drops. Patients with the following condition should not typically use this medication, for example:

Although Hydroxyamphetamine and Tropicamide eye drops can be prescribed to pediatric patients, infants may be more likely to experience side effects when using this medication. As children are more sensitive to the effects of Hydroxyamphetamine and Tropicamide, they may be prescribed a lower dose of medicine.

Once Hydroxyamphetamine and Tropicamide eye drops have been administered, the patient's pupils will dilate. During this time, the patient may experience blurred vision and have particular trouble seeing items which are near to them. Due to this, patients should not attempt to operate machinery, carry out potentially dangerous tasks or to drive whilst under the effects of this medicine.

Hydroxyamphetamine and Tropicamide eye drops can make a patient's eyes more sensitive to light. Patients may need to wear sunglasses after their eye examination as this can help to protect their eyes from bright lights and/or sunlight.

In most cases, the blurred vision and sensitivity to light caused by Hydroxyamphetamine and Tropicamide eye drops will last for less than 24 hours. If patients are still experiencing side effects after this time, they should contact their physician for medical advice.

Before using Hydroxyamphetamine and Tropicamide eye drops, patients should tell their doctor if they have any existing allergies. This includes allergies to medicines, foods, dyes, preservatives or animals. In rare cases, patients may experience an allergic reaction when using Hydroxyamphetamine and Tropicamide eye drops. If so, they will require immediate medical attention. An allergic reaction may include the following symptoms:

  • Rash on the skin
  • Itching
  • Hives
  • Difficulty breathing
  • Difficulty swallowing
  • Hoarseness
  • Swelling of the hands, face, throat, lips, tongue and/or mouth

Storage

When storing Hydroxyamphetamine and Tropicamide eye drops, patients should follow the medication guidelines which are supplied with the medicine. In most cases, however, Hydroxyamphetamine and Tropicamide eye drops can be kept at room temperature. They should be kept away from moisture, heat and direct light as these elements can have a damaging effect on the medicine.

When storing medication, patients should ensure that no one else has access to it. It is particularly important to prevent children and/or pets from gaining access to this medicine.

If patients have any Hydroxyamphetamine and Tropicamide eye drops left over, they should dispose of the medicine carefully. It is not safe to throw medicine out with regular household waste. In order to dispose of Hydroxyamphetamine and Tropicamide eye drops, patients should contact their pharmacist or physician's office and use a specialist medicine disposal service.

Summary

Although Hydroxyamphetamine and Tropicamide eye drops are occasionally used to treat eye conditions, they are regularly used to facilitate diagnostic testing. In order for physicians to be able to carry out accurate assessments, it's important that the patient's pupils are dilated.

Hydroxyamphetamine and Tropicamide eye drops provide an easy and non-invasive method of dilating the pupils and ensure that the patient's eye exam can be carried out thoroughly. Whilst patients may experience blurred vision and/or sensitivity to light following the application of Hydroxyamphetamine and Tropicamide eye drops, these side effects are normally fairly short-lived.

In order for eye conditions to be accurately diagnosed, it's vital that physicians are able to perform comprehensive eye exams. As Hydroxyamphetamine and Tropicamide eye drops enable ophthalmologists to examine the patient thoroughly, they are a widely-used medicine and are suitable for the vast majority of patients.
