Pataday Side Effects
Sore throat and symptoms of the common cold are side effects that have been reported in about 10 percent of people taking Pataday. Side effects that were seen in less than 5 percent of people included blurred vision, dry eyes, and headaches. Some side effects, although rare, are potentially serious and require medical attention, such as inflammation of the cornea or an allergic reaction.
Just like any medicine, Pataday™ (olopatadine ophthalmic solution) can cause side effects. However, not everyone who uses the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Pataday. Your healthcare provider can discuss a more complete list of Pataday side effects with you.)
Pataday has been studied thoroughly in clinical trials, in which the side effects of a group of people taking the drug are documented and compared to another group taking a placebo eyedrop that did not contain any active ingredient. As a result, it is possible to see what side effects occur, how often they appear, and how they compare to the group taking the placebo.
In these studies, the most common Pataday side effects were symptoms of the common cold (such as a runny or stuffy nose) or a sore throat, with about 10 percent of people experiencing such problems. Other reported side effects (occurring in less than 5 percent of people) included:
- Blurred vision
- Burning or stinging of the eyes
- Dry eyes
- A foreign-body sensation (feeling like something is stuck in the eye)
- Redness of the eye
- Eyelid swelling
- Eye pain or itching
- A feeling of weakness
- Back pain
- Flu symptoms (such as a fever or chills)
- Stuffy or runny nose
- Taste changes.
It should be noted that many of these side effects are also symptoms of eye allergies, and it is possible that they are not really side effects of Pataday at all.
