The natural relief stuff would open a can of worms, so just some warnings about the OTC allergy meds, eye drops etc.
Main culprit aiming at your yen are the decongestants added. One trying to get relief from allergies should at least understand this dynamic. Only motive sharing this is to help avoid bad stuff.
The eye drops...
Until recently, you could not get pure antihistamine eye drop over the counter. Zatidor is now available, and my advice to only go with this unless you are doing an RX for Patanol or something equivalent. Avoid the other products because they got a trap there designed to keep you coming back.
Think about it. A pure antihistamine eye drop requires a doctors intervention but antihistamine plus the decongestant, far more toxic, is available as fast as you can fire up the credit card.
The decongestant "gets the red out". Works really well and fast. Couple downsides however they don't tell you about. The decreased circulation from collapsing the blood vessels lessens the body's ability to deal with the allergen. Secondly the constriction is met with a systemic response to blow the blood supply up again. The addiction cycle starts in as little as 3 days.
Works real good. Gets the eyes white, but hell, you are having to use them more often and back for another bottle. Eyes getting redder and redder. Dam those allergies. At lease there is relief from the drug counter.
Afrin type nose sprays are the same. Not to say they don't work in a crisis, but use them for a week and you are a committed customer.
Same, maybe to a lesser degree with the RX antihistamine plus decongestant pills. Use them for a month and you are crawling back for a prescription refill as long as you live.
You may have seasonal or permanent allergies, but may also have been in some temporary crisis that needed a bit of chemical love to get you through the stuffed nose. By the time you are hooked on the combo bombs, you can't tell the difference between the long gone allergy and struggling with the current addiction.
I've helped get many off of the Claritin-D, Allegra-D poisons by having them stop the pills and take only the antihistamine component. Both nostrils will slam shut in the revolt of being denied the vasoconstrictor..
Use the Afrin drug in one nostril only to breathe as the body revolts. The other nostril will open and heal within 2 weeks. Then stop the spray and that nostril will close completely. Couple weeks later, you can breathe normally again.
Just a note on those using things like Flonase nasal spray for allergies. Goes as well for steroid inhalers for asthma. Be really sure you gargle deeply and spit out a couple minutes after you have used them. These things work different from antihistamines and rely on shutting down the immune system anywhere the mist or powder touches. Means the back of your throat. Got to wash off the collateral exposure so not to be open to every bacteria and virus you breathe in.
Okay, done said my piece. Can let this fred retire off to the bottom of the bird cage.
