Like most folks with ADHD I have some spares for situations like the recent shortage.
Every so often it seems like the pill isn’t really doing it’s job. I start to wonder if I’m building up a tolerance, and need to ask for an increased dosage, and then suddenly I’m doing fine again.
Well, I was going through that recently, and I realized I just switched to my newest bottle. Now it feels just as strong, if not stronger than it used to be. As it happens, I tend to have some spares from days I forget and whatnot, so it’s been maybe 2 weeks. That also means this last bottle was over month old, too. I wish I could remember if I’d just changed to the new bottle the last time this happened too.
I’m using Walgreens, and the shape of the pill changed last month, so maybe there’s a different formulation? I just keep going through this feast and famine of medication efficacy, and Itd be nice to know if this is a problem I can actually solve without going to a higher dosage. Idk, maybe I’ll keep them in the fridge while Im not using them or something.
The ideal storage temperature should be on the bottle but you should also be able to look it up. Lots of things can cause lots of medications to degrade aside from just time, including temperature, moisture, and light (particularly UV). For instance, you’re not supposed to keep most medications in the bathroom even though they often call that a “medicine cabinet” because many people take hot, steamy showers, and both moisture and heat can degrade medications. An NIH paper titled “Medication Storage Appropriateness in US Households” states for Adderall: “Extended-release capsules: Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F); protect from light.” (So don’t keep it on the windowsill next to your bed either).
If you’re worried about variances in specific binding agents or other parts of the formulation that could vary by manufacturer, call the pharmacy. Ask to speak to the pharmacist on duty about the ideal storage conditions, because they know all kinds of weird shit about the specific ingredients and how to store them (one time I called to ask if there was sorbitol in the liquid medication I was giving a patient because it could explain their diarrhea). It’s also possible, like you mentioned, that you just have some bizarre genetic mutation that makes some normally inert binding or coloring agent interact weirdly with the active ingredient and/or you (the pharmacist wouldn’t be able to figure you being a freak of nature out, but they could try to make sure you don’t get meds from that manufacturer again).
My personal recommendation as a person who went through nursing school (they’re very worried about substance abuse and trafficking) with ADHD meds, is that you save your last medication bottle when you empty it. Keep exactly one pill in it in your bag as a backup for emergencies. The bottle will have your name and birthday and what the pills are so you’re covered for carrying a controlled substance, but you won’t be carrying all your meds around at once to spoil in the heat. As for taking them with food, try keeping some saltines or water crackers around and take 2-4 with the pill to avoid stomach upset.
