What is Paremyd, and how does it work?

- nausea
- vomiting
- pale skin (pallor)

Convenient One-Drop Solution for Dilation
- Convenient one-drop formulation is easier to administer than many current regimens consisting of a drop from two separate products.
For Patient and Practitioner Convenience
- Formulated to work quickly to fit busy patients' schedules and your patient flow.
- Only partial loss of accommodation, due to lower (0.25%) concentration of tropicamide.
- Minimizes inconvenience: Recovery begins within 90 minutes, with complete recovery typically in 6 to 8 hours.
Paremyd (hydroxyamphetamine hydrobromide, tropicamide) Solution should not be used in patients with angle-closure glaucoma or in those with narrow angles in whom dilation of the pupil may precipitate an attack of angle-closure glaucoma. This product is also contraindicated in patients who are hypersensitive to any of its components.
What is the dosage for Paremyd?
One to two drops in the conjunctival sac. The onset of action with Paremyd Solution occurs within 15 minutes followed by maximum effect within 60 minutes. Clinically significant dilation, inhibition of pupillary light response, and partial cycloplegia last 3 hours.
Mydriasis will reverse spontaneously with time, typically in 6 to 8 hours. However, in some cases, complete recovery may take up to 24 hours.
Is Paremyd safe to use while pregnant or breastfeeding?
- It is also not known whether Paremyd can cause fetal harm when administered to a pregnant woman or can affect reproduction capability.
- Paremyd should be given to a pregnant woman only if clearly needed.
- It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Paremyd is administered to a nursing woman.
