Humorsol Patient Information including How Should I Take

What should I discuss with my healthcare provider before using demecarium bromide ophthalmic (Humorsol)?

Rarely, demecarium bromide ophthalmic may cause retinal detachment. Tell your doctor if you have any type of retinal disease, if you have had a retinal tear, if you are nearsighted, or if you have had cataract surgery. These conditions may increase the risk of retinal detachment.

Before using this medication, tell your doctor if you

  • have heart failure,
  • have high or low blood pressure,
  • have ever had a heart attack,
  • have asthma,
  • have a stomach ulcer or stomach spasms,
  • have epilepsy,
  • have hyperthyroidism (an overactive thyroid),
  • have blockage of your urinary tract or difficulty urinating, or
  • have Parkinson's disease.

You may not be able to use demecarium bromide ophthalmic, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.

If you wear contact lenses, remove them before applying demecarium bromide ophthalmic. Ask your doctor if contact lenses can be reinserted after application of the medication.

Demecarium bromide ophthalmic is in the FDA pregnancy category X. This means that it is known to cause birth defects in an unborn baby. Do not use demecarium bromide ophthalmic if you are pregnant or could become pregnant during treatment.

It is not known whether demecarium bromide passes into breast milk. Do not use demecarium bromide ophthalmic without first talking to your doctor if you are breast-feeding a baby.

How should I use demecarium bromide ophthalmic (Humorsol)?

Use demecarium bromide ophthalmic eye drops exactly as directed by your doctor. If you do not understand the instructions, ask your doctor, pharmacist, or nurse to explain them to you.

Wash your hands immediately before using the eye drops.

If you wear contact lenses, remove them before applying demecarium bromide ophthalmic. Ask your doctor if contact lenses can be reinserted after application of the medication.

To apply the eye drops:

  • Tilt the head back slightly and pull down on the lower eyelid. Position the dropper above the eye. Look up and away from the dropper. Squeeze out a drop and close the eye. Apply gentle pressure to the inside corner of the eye (near the nose) for about 1 minute to prevent the liquid from draining down the tear duct. If you are using more than one drop in the same eye, repeat the process with about 5 minutes between drops. If you are using drops in both eyes, repeat the process in the other eye.

Do not touch the dropper to any surface, including the eyes or hands. The dropper is sterile. If it becomes contaminated, it could cause an infection in the eye.

Do not use any eyedrop that is discolored or has particles in it.

Store demecarium bromide ophthalmic at room temperature away from moisture and heat. Keep the bottle properly capped.
