So I've read that skin rashes are quite uncommon and Stevens-Johnson Syndrome is quite rare from Modafinil use, however, yesterday(Sunday) I took 100mg at 10:00 for the first time to enjoy a nice day of studying for midterms. The Modafinil gave me an amazing lucidity and memory recognition, but I did experience a few common side effects(gas, itchy skin) that would come and go throughout the day which didn't bother me. Nearing the end of the night, around midnight, I noticed an area (about the diameter of a cotton makeup pad) of splotchy red, rash-like dots with a pronounced red area in the middle of the area, on my inner left thigh. It looked like a harsh bruise(internal bleeding) but red, rather than purple. This area was not present when I took a shower about 3 or 4 hours prior to noticing this area. Promptly, I drank a double dose of my liquid multivitamin (Cellfood Silica) to hopefully mitigate any adverse reactions. What I suspect this to be is an adverse allergic/hypersensitivity reaction to the Modafinil, but early in the day I picked at a little zit/ingrown hair near the epicenter of this splotchy area, so it may have been a cause since it bled a little. No other rashes have been found in any areas of the body(may rule out SJS because of the symmetrical nature of the disorder). Either way, I will reluctantly give up studying with modafinil and just stick to my gingko/vinpocetine/ALCAR/caffiene regimen for fear of progressive allergic/hypersensitivity reactions to the Modafinil. It's quite disappointing that such a powerful memory/concentration enhancer causes such pronounced and proliferant side effects as SJS and TEN(Toxic Epidermal Necrolysis).
I hope anyone taking Modafinil will exercise extreme caution when using this drug, and to regularly check for any signs of rash. I'm certain this reation will dissipate within a few days, although, I've read it may possibly progress into SJS or TEN, I have doubts that one time use will trigger any sort of cascading reaction within a relatively healthy individual.
I have attached a photo of the area, with the area outlined in blue and a penny for reference, the photo was taken today, and the red splotchy spots were much darker and more prevalent last night. For reference, I took half a 200 mg tablet from the generic company, Spier Pharmaceuticals, so maybe the generic tablet has excess impurities or an improper synthesis technique that may cause excess/abnormal/rare side effects. I'd love to be able to use Modafinil on rare occasions for studying and cramming, but I don't want to risk having my skin fall off, which is disappointing since I had such a pronounced stimulating/nootropic effect.
