    Some people who have taken Viagra notice that an hour or so after taking the drug that they experience visual problems. For example, seeing a bluish tinge, increased sensitivity to light, or blurred vision. While this is usually only temporary, it's wise to visit your GP or optician if these symptoms persist or worsen after a few hours. tamoxifen polyps « Prilosec / Prevacid / Nexium Federal Court Lawsuits For Kidney Injury Consolidated By MDL Established In August 2017 | Main | Breast Implant Associated Anaplastic Large-Cell Lymphoma (BIA-ALCL): New Medical Journal Article About Treatments » (Posted by Tom Lamb at Drug Injury Watch.com) As reported previously, the erectile dysfunction (ED) drugs Cialis (tadalafil), Levitra (vardenafil hydrochloride), and Viagra (sildenafil citrate) have been associated with a type of sudden vision loss called Nonarteritic Anterior Ischemic Optic Neuropathy (NAION). In July 2005 the FDA ordered warnings be put on the package insert labels of these ED drugs, or impotence drugs, to the effect that some users of Cialis, Levitra, and Viagra have developed NAION, a form of blindness. At the same time, however, the FDA stated that it is impossible at present to know if NAION is a side effect of these ED drugs, or an unrelated medical condition. In June 2006 Health Canada issued a Public Communication alerting Canadians that the drug companies Eli Lilly (Cialis), Bayer (Levitra), and Pfizer (Viagra) were in the process of sending a so-called "Dear Doctor" letter to inform healthcare providers in Canada about changes to the respective package insert, or label, for these drugs regarding this vision loss, or NAION, side effect. Now, 11 years later, in August 2017, there is some additional information about the increased risk of developing the eye or vision side effect NAION which is included in a recent label change for Viagra, Cialis, and Levitra. ______________________________________ Strictly Confidential, No Obligation. ______________________________________ From a comparison of the relevant parts of the two most recent drug labels for Levitra, below, you can see what was added by means of this August 2017 label change concerning NAION as a possible adverse drug event or adverse reaction (in the second and third paragraphs of the current drug label).

    A high dose of the erectile dysfunction drug sildenafil citrate (Viagra) led to irreversible eye damage in a 31-year-old man, authors of a case study reported. The patient developed "persistent retinal toxicity" after taking far more than the recommended dose, Richard Rosen, MD, of New York Eye and Ear Infirmary of Mount Sinai in New York City, and colleagues wrote in The patient in question presented at an urgent care clinic complaining of red-tinted vision in both eyes. He had begun experiencing the symptoms 2 days earlier after ingesting liquid sildenafil citrate he had purchased over the internet from a non-pharmacy source. The patient further reported that he drank the sildenafil directly from the bottle and didn't know the exact dosage he ingested, but that it was much more than the recommended 50 mg dose. Visual disturbances are known to be potential side effects of sildenafil citrate. For example, one study found that a single oral dose of 100-mg sildenafil citrate given to healthy young men "led to small but statistically significant transient changes of outer and inner retinal function" that resolved in 24 hours. Here, the patient's symptoms failed to improve in the year after initial diagnosis, despite a wide variety of treatments, which included -- upon presentation -- topical prednisolone acetate four times a day in both eyes, brinzolamide 1% three times a day in both eyes, and brimonidine tartrate twice daily in both eyes. Sildenafil, the active ingredient in the erectile dysfunction drug Viagra®, could cause unusual visual responses in people who carry a common mutation for eye disease and may have long-term detrimental effects on their vision, UNSW Australia researchers warn. Sildenafil can inhibit an enzyme which is important for transmitting light signals from the retina to the brain, and it is already known from clinical trials of Viagra® that its use in high doses can cause transient disturbances in the vision of some healthy people. "Side effects can include sensitivity to bright light, blurred vision and altered colour vision," says Dr Lisa Nivison-Smith, of the UNSW School of Optometry and Vision Science. "We are concerned that people who have normal vision but who carry a single copy of the mutant gene for the blinding disease, Retinitis Pigmentosa, could be more susceptible to these changes." A team led by Dr Nivison-Smith and UNSW's Professor Michael Kalloniatis studied the effects of a single dose of sildenafil on normal mice and mice with a single copy of the mutant gene. The results are published in the journal Experimental Eye Research. They found the normal mice had a transient loss of visual function after sildenafil treatment, but this effect was heightened in the mice with the mutation, and the response lasted longer. They also found early signs of cell death in the eyes of carrier mice, but not in the normal mice, suggesting sildenafil may cause degeneration in carriers of retinal disease.

    Corticosteroid drugs — including cortisone, hydrocortisone and prednisone — are useful in treating many conditions, such as rashes, lupus and asthma. But these drugs also carry a risk of serious side effects. Working with your doctor, you can take steps to reduce these side effects so that the benefits of corticosteroid treatment outweigh the risks. Corticosteroids mimic the effects of hormones your body produces naturally in your adrenal glands, which are small glands that sit on top of your kidneys. When prescribed in doses that exceed your body's usual levels, corticosteroids suppress inflammation. This can reduce the signs and symptoms of inflammatory conditions, such as arthritis and asthma. Corticosteroid drugs are used to treat rheumatoid arthritis, lupus, asthma, allergies and many other conditions.

    Rabbis have risen to the occasion and found a way for men who want to enjoy their Passover to take the erectile dysfunction medication Viagra without violating the laws about consuming hametz (leaven) leaven during the holiday. Four years ago, The Jerusalem Post revealed in a widely quoted story that taking Viagra during Passover was forbidden by Jewish law because its coating was made with hametz. Rabbi Menahem Rosenberg, the rabbi of Clalit Health Services, then confirmed that Viagra (sildenafil citrate) was not kosher for Passover because of the coating.
