I took Nasacort (a corticosteroid treatment for allergic rhinitis) from September to November. When I realised my periods became irregular, I stopped. I've never had any problems with it and now it's all messed up. I have cramps and breast tenderness in mid cycle, something I never had except just before my period. Other times, I have cramps for a few days and nothing happens. I had my period each month since then but it doesn't come as easy as before. I'd just like to know if it happened to someone else before. Can I expect everything to go back to normal by itself? Someone told me it can happen with corticosteroid drugs. I hope everything I said is clear, i don't speak english! Thanks for your help!
Did you take steroid tablets? If so, then yes, this could be related with your periods being irregular as steroids interfere and can affect a lot of your bodily processes and why they should only ever be used for short periods of time only. Give it some time and your periods should start to normalise naturally. If not, then go and see your doc.
If you took the steroids as a nasal spray, for the hay fever, then this should not interfere with anything, being such a low dose, so you probably need to go and see your doc and look for other causes.
Yes, it was as a nasal spray. I took the highest dose for 2 months. I can't believe it doesn't have any effects because all began after I took it. And I've never had these kind of problems before... Well, thanks for your answer!
Well, possibly if it was a very high dose, then there could have been some effects then and if your problems only started after using this, then this sounds probable. Normally though, inhaled steroids such as asthma inhalers do not normally have systemic effects, but may be nasal sprays are different.
Anyway, if you are not taking this anymore, then I would just wait and see what happens to your periods and try and let them resolve naturally. Your body should adjust in time. If not then go and see your doc.
However, can I strongly suggest that you do not use a steroid spray for hay fever again? There are plenty of natural, safe and very effective alternative treatments around now that do actually work very well. These include acupuncture, homeopathy and herbal medicinal products.
As a young adult in my 20's, I developed asthma suddenly and severely as a result of other allergies. I was put on ventolin and a steroid inhaler by my doc at the time, as I was always getting bronchitis after a cold. This continued for some years, until I started getting a hoarse voice from taking the steroids, so I decided to stop. A friend of mine then introduced me to acupuncture and after only two treatments, my breathing and health generally were vastly improved. After a course of about 8 treatments I had no problems. Not long after that, I discovered homeopathy and now use a mixture of homeopathy and acupuncture to resolve any health problems that occur for me. No more steroids or ventolin or asthma for that matter.
