Varför detta händer
Prednisolone is a steroid medication that interferes with how your body processes vitamin D. It can speed up the breakdown of vitamin D and also reduce how much calcium your body absorbs from your food, which vitamin D normally helps with.
Vad du bör göra
Tillbaka till innehållYou can take these medicines together, but your doctor may need to monitor your vitamin D and calcium levels with blood tests. In some cases, a higher dose of colecalciferol or an additional calcium supplement may be recommended to protect your bone health while you are taking steroids.

Viktiga försiktighetsåtgärder
Tillbaka till innehållHyperkalcemi (högt kalcium i blodet)
Do not take colecalciferol if you have high levels of calcium in your blood or urine, or if you have severe kidney stones, as vitamin D increases calcium absorption and can worsen these conditions.
Infection exposure (Chickenpox, Shingles, Measles)
You must avoid contact with anyone who has chickenpox, shingles, or measles. If you are exposed, contact your doctor immediately, as these infections can be life-threatening while taking prednisolone.
Steroid Withdrawal
Do not stop taking prednisolone suddenly if you have been on it for more than 3 weeks. Your dose must be reduced gradually to avoid a serious adrenal crisis.
Steroid Emergency Card
You must carry a Steroid Treatment Card or MedicAlert identification at all times to alert healthcare professionals that you are taking a high-dose steroid in case of an emergency.
Varningar för mat och dryck
Tillbaka till innehållAlkohol
It is best to avoid or strictly limit alcohol while taking colecalciferol. Long-term heavy alcohol use can interfere with how your body absorbs and processes Vitamin D, making the treatment less effective.
It is best to avoid or strictly limit alcohol while taking prednisolone. Both alcohol and prednisolone can irritate the lining of the stomach, and using them together increases your risk of developing stomach ulcers or indigestion. Additionally, long-term use of both can increase the risk of thinning bones (osteoporosis).
Caffeine (Coffee, Tea, Energy Drinks)
Prednisolone can increase the effects of caffeine. You may find that you feel more jittery, anxious, or have trouble sleeping if you consume caffeine while taking this medicine. It is also worth noting that both caffeine and prednisolone can increase stomach acid, potentially leading to stomach upset.
Salt (Sodium)
Prednisolone can cause your body to retain salt and water, which may lead to swelling (oedema) and increased blood pressure. It is advisable to limit your intake of very salty foods, such as processed meats, crisps, and canned soups, while on this medication.
Sugary Foods
Prednisolone can increase your blood sugar levels. If you have diabetes, you may need to monitor your blood glucose more closely. Even if you do not have diabetes, it is sensible to avoid excessive amounts of sugary foods and drinks.
Fettrika måltider
Colecalciferol is a fat-soluble vitamin. It is best absorbed by your body when taken with a meal that contains some fat (such as eggs, avocado, nuts, or dairy).

Can I take Sertraline and Fluoxetine together?
Taking sertraline and fluoxetine together significantly increases the risk of a rare but serious condition called serotonin syndrome. This happens because both medicines work by increasing the level of a chemical called serotonin in your brain. If levels get too high, it can cause symptoms like shivering, diarrhoea, confusion, severe muscle tightness, fever, and even seizures. Additionally, fluoxetine can slow down how your body breaks down sertraline, leading to a build-up of the drug in your system and increasing the risk of side effects.
