Hydrocortisone
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
Contents of the pack
Hydrocortisone contains a substance called hydrocortisone (sometimes also called cortisol). Hydrocortisone is a glucocorticoid. It belongs to a group of medicines called corticosteroids. Glucocorticoids are produced naturally in the body and help maintain general health and well-being.
Hydrocortisone is used to treat a disease known as adrenal insufficiency or cortisol deficiency. This occurs when the adrenal glands (located just above the kidneys) do not produce enough cortisol. Patients with long-term (chronic) adrenal insufficiency need replacement therapy to survive.
Hydrocortisone replaces the missing natural cortisol in adrenal insufficiency.
Do not take Hydrocortisone
Warnings and precautions
Consult your doctor or pharmacist before starting to take Hydrocortisone.
Contact your doctor immediately if you experience muscle weakness, muscle pain, cramps, and stiffness while using hydrocortisone. They may be symptoms of a condition called thyrotoxic periodic paralysis, which can occur in patients with hyperthyroidism treated with hydrocortisone. You may need additional treatment to alleviate this condition.
Contact your doctor if you experience blurred vision or other visual disturbances.
Taking Hydrocortisone with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Some medicines may increase the effects of Hydrocortisone, so your doctor will monitor you closely if you are taking these medicines (including some for HIV: ritonavir, cobicistat).
During long-term treatment with medicines for the treatment of infections (antibiotics), your doctor may need to adjust your dose of Hydrocortisone. If used with mifepristone, a medicine used to interrupt pregnancy, the effect of Hydrocortisone may be reduced.
Also, consult your doctor or pharmacist if you are taking any of the following medicines, as you may need to have your dose of Hydrocortisone changed:
Taking Hydrocortisone with food and drinks
Do not take the medicine with grapefruit juice, as it will interfere with its action.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
It is essential to continue treatment with Hydrocortisone during pregnancy. It is unlikely that treatment in pregnant women with adrenal insufficiency will produce harmful effects in the mother or the child. If you become pregnant, you should inform your doctor, as your dose of Hydrocortisone may need to be adjusted.
You can breastfeed while taking Hydrocortisone tablets. Hydrocortisone is excreted in breast milk. The doses of hydrocortisone used as replacement therapy are unlikely to have any effect on the child. However, inform your doctor if you plan to breastfeed.
Fertility in women with adrenal insufficiency or cortisol deficiency may be reduced. There are no data to indicate that Hydrocortisone, at the doses used in replacement therapy, affects fertility.
Driving and using machines
The influence of this medicine on the ability to drive and use machines is small. Extreme fatigue and brief episodes of dizziness (vertigo) have been reported. Untreated or poorly treated adrenal insufficiency reduces the ability to concentrate and affects the ability to drive and use machines. Therefore, it is essential to take this medicine as your doctor has indicated when driving or using machines. If you feel affected, do not drive or operate machines until you have discussed the problem with your doctor.
Hydrocortisone contains lactose
This medicine contains lactose. If your doctor has told you that you have an intolerance to some sugars, consult them before taking this medicine.
Information for athletes

Follow exactly the instructions of administration of this medicine indicated by your doctor. In case of doubt, consult your doctor or pharmacist again. The dose is specific for you and has been decided by your doctor.
The usual maintenance dose in adults is 20-30 mg per day, administered once a day in the morning. In patients with some residual cortisol production, a lower dose may be sufficient. The highest maintenance dose studied is 40 mg. The lowest possible maintenance dose should be used.
The recommended dose in children and adolescents is 10-30 mg in divided doses.
The tablets should be taken orally with a glass of water upon waking, preferably in an upright position, and on an empty stomach. The tablets should not be chewed or crushed. If more than one administration is needed per day, the morning dose should be taken as indicated; additional doses can be taken with or without food.
Need for additional doses of Hydrocortisone
During short-term or temporary conditions, such as infections, fever, or physical stress like surgery, you will need more hydrocortisone, as the body cannot produce the additional cortisol needed in these situations. Therefore, the dose should be temporarily increased, and your doctor may advise you to take other hydrocortisone tablets instead of or in addition to Hydrocortisone. Consult your doctor and follow their instructions on how to handle these situations.
The following signs and symptoms may indicate that you need to take additional doses of Hydrocortisone or other medicines containing hydrocortisone: fatigue, weight loss, stomach upset, feeling dizzy when standing up from sitting or standing, darkening of the skin, especially in skin folds and exposed areas. Contact your doctor as soon as possible if you notice any of these signs or symptoms.
Seek medical attention immediatelyif you experience any of the following signs or symptoms: severe weakness, fainting, abdominal pain, nausea, vomiting, back pain, confusion, decreased level of consciousness, delirium (a state of great mental confusion).
If you take more Hydrocortisone than you should
Taking too high a dose of this medicine for more than a few days can be harmful to your health. It can cause high blood pressure, weight gain, and excessive blood sugar. Sometimes it is necessary to increase the dose so that the body can handle certain stressful situations, such as fever. If you need extra doses frequently and periodically, you should consult your doctor to reconsider your maintenance dose.
In case of overdose or accidental ingestion, consult your doctor, pharmacist, or call the Toxicology Information Service, phone 915 62 04 20, indicating the medicine and the amount taken.

If you forget to take Hydrocortisone

If you stop taking Hydrocortisone
Stopping the intake of Hydrocortisone can be life-threatening. Therefore, it is essential to continue taking this medicine as your doctor has indicated. Do not stop treatment without consulting your doctor.
Do not stop treatment abruptly. The reduction of the dose should always be gradual, to avoid possible effects on the corticosteroids produced by our body.
If you have any other questions about the use of this medicine, ask your doctor or pharmacist.
