How can I deal with hiccups while at home?

My husband had hiccups continuously for 3 days straight after receiving a cortisone shot. We discovered that this is a rare side effect. He used a spoonful of peanut butter, as suggested by others online, to get rid of them long enough to get a few hours of rest at a time. It was awful as I’m sure you’re experiencing. Perhaps prednisone has the same rare effect as cortisone. He tried many things over these 3 days but peanut butter worked the best.

What does your doctor say? Has he addressed this problem?

You seem to have more than just a case of basic hiccups, but I'll share what works for my family. We fill a 16 oz glass of water and drink it slowly while holding our breath the enter time. You'll feel a strong pull in your throat while swollowing. The slower you drink and the longer you hold your breath the more success you have. Plus it's a good way to flush out your kidneys!

Well, the hiccups have finally passed, after 8-10 days, including days its was 24x7. The treatment was thorazine, which did bring me significant fatigue. I stopped taking it 3 days ago. The choice of medication - there are many medications that address hiccups - was made by my neurologist in consideration of my basic problem, which is a demyelination disease becoming more recognized, namely Clippers. I was preparing to switch to metoclopramide as a medication when the hiccups went away.

Thanks for everyone's suggestions. I will definitely try some of the home-based ones if and when I have milder occurrences of hiccups. Enjoy the summer!

Hiccups are cause mostly by diaphragm. It can be due acid reflux, etc. Google it. See a good GI doctor. Never heard anyone taking Gabapentin for hiccups. I thought G is for pain only. Please see a good GI doctor. Not just a GI Doctor. A good one.

Thanks for sharing the term Clippers. I have long Covid and have in clinical trials for two years. There was a month that i hiccuped 18 hours a day, like 8 hiccups a minute for 45 minutes. Sure enough, I see science has confirmed demyelination disease and the link to Covid.

Well, the hiccups returned, not as severely but definitely as annoyingly. This time I was successful for a while with home time remedies, such as stopping drinking coffee, which had produced very minor burps or belches which would turn into hiccups. The hiccups went away quickly for a whole day or two before returning. I also found that seriously holding my breath (mouth shut, fingers squeezing nose and counting 6-7 hiccups before gasping for air) worked twice, but not a third time. So, a prescription for Metoclopramide came to the rescue and I have been hiccup-free for almost a week. I like this medication, it doesn't make me sleepy and it calms my digestive tract, which had also produced small burps and belches starting hiccups. There is a psychological factor in hiccuping, for sure: hiccuping after lunch, I took my first Metoclopramide pill and the hiccups stopped immediately!
