Hello,I have been taking plaquenil also known as hydroxychloroquine since April 2002. I have had no side effects from this antibiotic, and have regular eye exams to be on the safe side.
Here is a post I wrote awhile back, and thought I would post it here as it has some good info on Plaq:
One side effect that worries people is the possible eye damage the Plaq can cause. It is important to have an eye exam prior to starting the Plaq, and another eye exam every 3 - 6 months.
This drug like all others have risks. For me, the benefits outweighed the risk. It is up to the individual to decide if the risks are worth the benefits.
Before taking Plaq, I couldn't use my right hand, now I have 75% use of my hand. The use of my hand is important to me...So as long as my eye check ups are good, I plan to keep taking it.
I have been on Plaquenil since April 1, 2002. I had just had an eye exam 2 months prior, so my LLMD and eye doc didn't feel another eye exam was necessary.
I do however have to go to the eye doc every 3 months for an eye exam. I have had 3 eye exams to date. My last one was just a few weeks ago, everything looks great.
I don't have to go back for another exam until June.
I also wanted to add that my Eye doc (consulted with my LLMD) has me taking Vitamin A & E. I also take Lutein. The eye doc said that they will help protect the eye from the Plaq.
Here is some information I found when I researched Plaq before I started to take it.

The Plaquenil side-effect of greatest concern involves the eyes. The likelihood of developing Plaquenil eye problems depends upon the dose and duration of treatment. Eye problems are more common when very large doses are ingested and usually take months or years to occur. Eye side-effects from Plaquenil also may be more common in people over the age of 60.
Eye problems related to antimalarial drugs were more common years ago than what is experienced today. There are at least 3 reasons for this. First, Plaquenil seems safer than past antimalarial drugs. Second, larger doses of the antimalarial drugs were prescribed in the past than are currently recommended.
Third, there is a greater awareness of the potential for antimalarial eye problems. Thus, patients have thorough eye examinations more frequently now than was once the practice. With the currently recommended doses of Plaquenil, the risk of eye side-effects is about 3%.
In the past, it was believed that the eye side-effects of antimalarial drugs were irreversible and even progressive after the drug was discontinued. However, with the proper precautions, irreversible or progressive eye changes due to Plaquenil are extremely rare.
Symptoms of Plaquenil eye side-effects include: blurred vision, sensitivity of the eyes to sun light, decreased night or color vision, decreased ability to see objects at the edge of vision, black spots in the vision or light flashes or streaks.
If any of these visual changes occur, the Plaquenil should be immediately stopped and an eye specialist (ophthalmologist) consulted. Since early Plaquenil eye problems can occur without symptoms, regular examinations by an ophthalmologist are essential--even if vision is normal.
It is common to recommend eye examinations every 6 months. If the ophthalmologist detects possible eye toxicity, the Plaquenil should be immediately discontinued

The management of patients on plaquenil has been a controversial subject. Alot of the concerns are related to the problems caused by chloroquine, the predecessor to hydroxychloroquine (Plaquenil).
It was much more toxic to the retina and much more likely to cause permanent visual problems. Hydroxychloroquine, on the other hand, is much less toxic to the retina and there have been fewer reported eye problems. In general, a baseline ophthalmic examination should be performed upon initiation of therapy. In addition, a central visual field test and color photographs of the retina are usually taken at that time.
There are differing opinions regarding subsequent follow-up exams. The most conservative opinion would include exams every 6 months with repeat visual fields every 6 to 12 months.
My general feeling is to perform annual exams with visual field testing. One study determined that the risk of retina toxicity when patients are taking less than 6.5 mg per kilograms per day is rare.
This means that a person weighing 150 lbs is likely to be safe if they are taking 200 mg twice daily. I calculate this number regularly and if the person is on more than 6.5 mg per kg per day than I will follow them more closely.
I have been on the Plaquenil for 10 months, and haven't had any side effects, other than an initial herx.
