The recommended course of treatment largely depends on weighing up the benefits of corticosteroids against the side effects. If your illness is severe and corticosteroids are effective, treatment will often continue. However, continued treatment will not be recommended if:
There aren't usually any severe side effects if you take steroid injections, a steroid inhaler, or a short course of steroid tablets. However, prolonged treatment at high doses can cause problems in some people. Side effectsCorticosteroids are powerful medications that can sometimes have side effects. The risk of experiencing side effects depends on:
Please take time to read the patient information leaflet that comes with your medicine. Discuss any concerns or queries with your Pharmacist or GP. Side effects of steroid inhalersInhaled steroids usually have few or no side effects if used at normal doses. However, they can sometimes cause: Rinsing your mouth out with water after using your medication can help to prevent oral thrush. Using a device called a spacer with your medication can help to prevent many of the other problems. There's some evidence that steroid inhalers used by people with chronic obstructive pulmonary disease (COPD) can increase the risk of chest infections like pneumonia. Discuss this with your health professional if you’re concerned. A high dose of inhaled steroids can sometimes cause more serious side effects but this is rare. Side effects of steroid injectionsSteroids that are injected into muscles and joints may cause some pain and swelling at the site of the injection. However, this should pass within a few days. Steroid injections can also cause muscle or tendon weakness. This means you may be advised to rest the treated area for a few days after the injection. Other possible side effects in the area where the injection is given can include:
Steroid injections are often only given at intervals of at least 6 weeks. A maximum of 3 injections into one area is usually recommended. Steroids that are injected into a blood vessel (intravenous steroids) may cause more widespread side effects. Side effects of steroid tabletsSteroid tablets that are taken for a short period of time are unlikely to cause side effects. It’s sometimes necessary for steroid tablets to be taken for longer periods. In these cases, you may be more likely to develop troublesome side effects. However, this is not inevitable. Steroid tablets taken for longer than 3 weeks can cause:
If you need to take steroid tablets on a long-term basis, you may have regular checks and tests for conditions like:
Stopping your medicationIf you have troublesome side effects, don't stop taking your medication until your doctor says it's safe to do so. This is because you may experience withdrawal effects. Your dose may need to be reduced slowly over a few weeks or months. If you've been taking corticosteroids for a while, you may also need tests before you stop taking them. These will make sure that your adrenal glands are still working properly. Medicines that can interact with corticosteroidsCorticosteroids can interact with other medicines. This means that the effects of either medicine can be altered. There is less chance of this happening with steroid injections or sprays. However, it can occasionally happen if they're used at high doses and for a long time. If you want to check that your medicines are safe to take with your medication, ask your Pharmacist or GP. Anticoagulant medicinesAnticoagulant medicines are medications that make the blood less sticky. They're often prescribed to people with a history of blood clots or an increased risk of developing them. Combining corticosteroids with anticoagulant medicines can sometimes make anticoagulants less effective. Alternatively, it can increase their blood-thinning effect. AnticonvulsantsAnticonvulsants are medicines used to prevent seizures (fits). They're often used to treat epilepsy. Anticonvulsants can reduce the effectiveness of corticosteroids. This means you may be advised to stop taking anticonvulsants whilst you're taking corticosteroids. This will depend on:
Diabetes medicationCorticosteroids can decrease the effectiveness of medications used to treat diabetes. If you need to take medication for diabetes with corticosteroids, your blood glucose levels will usually need to be checked more regularly. Your dose of diabetes medication may then need to be adjusted. HIV medicationCorticosteroids can sometimes interact with a type of medication known as protease inhibitors (like ritonavir). These are used to treat HIV. The HIV medication may increase the level of corticosteroid in your body. This might increase your risk of experiencing side effects. Live vaccinesSome vaccinations contain a weakened form of the infection they are designed to protect against. These are known as live vaccines. Examples of live vaccines include: Corticosteroids can weaken your immune system and make you more vulnerable to infection. This means you should avoid any live vaccine until at least 3 months after your course of corticosteroids has finished. Non-steroidal anti-inflammatory drugsNon-steroidal anti-inflammatory drugs (NSAIDs) are a group of commonly used painkillers. Some, like ibuprofen, are available over the counter. Combining NSAIDs and corticosteroids can increase your risk of developing: If you need to take both medications, you may be given a medication called a proton pump inhibitor (PPI). This helps to reduce the risk of stomach ulcers. |
