Patanase Side Effects
Bitter taste, nosebleeds, and headaches are the most common side effects reported with Patanase. Side effects of the medicine are typically mild, but you should seek medical attention immediately if you experience severe or frequent nosebleeds, excessive drowsiness, or an allergic reaction. Other rare but possible side effects of Patanase (occurring in less than 1 percent of people) include drowsiness, dry mouth, and the flu.
As with any medicine, side effects are possible with Patanase® (olopatadine nasal spray). However, not everyone who takes the medication will experience side effects. 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 Patanase. Your healthcare provider can discuss a more complete list of Patanase side effects with you.)
Patanase 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 not taking the medicine. As a result, 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 studies, the most common side effects of Patanase included:
- Bitter taste -- in up to 12.8 percent of people
- Headaches -- up to 4.5 percent
- Nosebleeds -- up to 3.2 percent
- Throat pain -- up to 2.2 percent
- Post-nasal drip -- up to 1.5 percent
- Coughing -- up to 1.4 percent
- Urinary tract infection (UTI) -- up to 1.2 percent.
