Common Side Effects of Travoprost
Travoprost has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the medicine (or taking a different medicine). This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these clinical studies, the most common side effect of travoprost was eye redness, which occurred in 35 to 50 percent of people. Other common side effects (which occurred in 5 to 10 percent of people) included:
- Less clear or sharp vision
- Eye discomfort or pain
- Feeling like something is stuck in the eye
- Eye itching.
Slightly less common travoprost side effects (occurring in 1 to 4 percent of people) included:
- Vision changes
- Inflammation of the eyelids
- Blurred vision
- Conjunctivitis ("pink eye")
- Dry eyes
- Crusting of the eyelids
- Eye sensitivity to light
- Darkening of the iris (the colored part of the eye) to a brown color
- Inflammation of the cornea of the eye (keratitis).
In addition to causing a darkening of eye color (which is usually permanent, even if the medication is stopped), travoprost can cause darkening of the eyelids and darkening and increased growth of the eyelashes. The eyelid and eyelash changes often get better after the medication is stopped.
Some side effects unrelated to the eyes were reported in 1 to 5 percent of people using travoprost. These side effects included:
- Accidental injury
- Chest pain
- Back pain
- A slow heart rate (bradycardia)
- The common cold
- Stomach problems
- High cholesterol
- High blood pressure (hypertension) or low blood pressure (hypotension)
- Prostate problems
- Sinus infection
- Loss of bladder control (urinary incontinence)
- Bladder infection (urinary tract infection or UTI).
