Steroids
Steroids are a medication which tone down the immune system and decrease inflammation. Inhaled steroids have very few side effects, but you should make sure to rinse out your mouth after using a steroid inhaler to avoid thrush. Since most inhaled steroids are used twice a day, brushing immediately after using the inhaler can be part of a daily routine. Oral steroids may be necessary for severe cases of asthma or autoimmune diseases. Short courses of oral steroids are thought to be safe, but long term steroid use can be associated with the following symptoms: weight gain, increased appetite, nausea, headache, personality changes, bruising, weak bones, slow growth, increased infections, stretch marks, facial hair, and increased susceptibility to certain infections.
