Cortef (Generic Hydrocortisone Oral) Overview
Hydrocortisone is a corticosteroid—a powerful anti-inflammatory medication that your body naturally produces in small amounts. When taken as a pill, it works by reducing swelling, calming an overactive immune system, and decreasing inflammation throughout your body. This makes it useful for treating conditions where the immune system attacks healthy tissue or where inflammation is causing serious problems.
Doctors prescribe hydrocortisone for conditions like adrenal insufficiency (when your body doesn't make enough of its own cortisol), severe allergic reactions, autoimmune diseases, certain cancers, and inflammatory bowel conditions. It's also used to manage symptoms of lupus and rheumatoid arthritis. Because hydrocortisone affects so many body systems, it requires careful monitoring and should only be used at the lowest effective dose for the shortest time possible.
This medication works quickly—often within hours—which is why it's valuable for acute flare-ups and long-term chronic conditions. However, its broad effects mean it can cause side effects, particularly when used long-term. This information is educational and does not replace advice from your healthcare provider.
Side Effects
Hydrocortisone is generally well-tolerated at prescribed doses, but because it affects multiple body systems, side effects are possible. Most people experience manageable effects, especially when taking lower doses or using the medication short-term.
Common Side Effects
Increased appetite and weight gain – Hydrocortisone can stimulate hunger and slow your metabolism, making it easier to gain weight
Sleep problems (insomnia) – The medication can cause restlessness, especially if taken late in the day
Mood changes – Some people experience increased irritability, anxiety, or mild mood elevation
Headaches – Mild to moderate headaches may occur, particularly when starting the medication
Nausea or stomach upset – Taking the pill with food usually helps prevent this
Increased thirst and frequent urination – Hydrocortisone can affect blood sugar and fluid balance
Serious Side Effects
High blood pressure – Prolonged use can raise blood pressure, requiring monitoring
Osteoporosis (weak bones) – Long-term use increases bone loss, raising fracture risk
Severe infections – Since hydrocortisone suppresses immunity, serious infections like pneumonia or tuberculosis may develop or worsen
Fluid retention and swelling – Particularly in legs, ankles, and face; can signal serious complications
Mental health changes – Rare cases of depression, anxiety, or psychosis require immediate attention
When to Seek Medical AttentionContact your healthcare provider if you experience persistent headaches, vision changes, chest pain, severe mood changes, signs of infection (fever, chills, persistent cough), or unusual bruising. If you have thoughts of harming yourself, seek emergency help immediately. For routine side effects like mild nausea or sleep problems, discuss with your doctor whether timing adjustments or food intake changes might help—don't stop taking the medication without approval.

Important: Never miss a dose without contacting your doctor—suddenly stopping hydrocortisone can cause serious withdrawal effects, including weakness, fatigue, and dangerous drops in blood pressure. If you miss a dose, take it as soon as you remember, but skip it if the next dose is almost due. Do not double up. Never change your dose or stop taking this medication without your doctor's explicit approval.
Drug Interactions
Hydrocortisone can interact with many medications because it affects how your body processes drugs and influences blood pressure, blood sugar, and immune function. Always tell your doctor and pharmacist about every medication, supplement, and herbal product you're taking.
Blood Pressure Medications (ACE inhibitors, beta-blockers)
Hydrocortisone may reduce the effectiveness of blood pressure-lowering drugs, requiring dose adjustments. Your doctor may need to monitor your blood pressure more frequently and adjust either medication.
Warfarin and Other Blood Thinners
Hydrocortisone can increase the anticoagulant effect of warfarin, raising bleeding risk. Blood work (INR levels) should be monitored closely, and your blood thinner dose may need adjustment.
Diabetes Medications (Insulin, Metformin, Sulfonylureas)
Hydrocortisone raises blood sugar levels, making diabetes harder to control. You may need higher doses of diabetes medication, and your blood sugar should be monitored more frequently.
NSAIDs (Ibuprofen, Naproxen, Aspirin)
Taking NSAIDs with hydrocortisone increases the risk of stomach ulcers and gastrointestinal bleeding. Use the lowest dose of NSAID for the shortest time, or ask your doctor about safer alternatives.
Certain Antifungal and Antibiotic Medications
Some drugs like rifampin and certain azole antifungals can speed up how your body breaks down hydrocortisone, reducing its effectiveness. Your hydrocortisone dose may need to be increased.
Immunosuppressants and Other Steroids
Combining hydrocortisone with other immune-suppressing drugs or steroids increases infection risk and side effects. These combinations require close medical supervision and careful dose management.

Frequently Asked Questions
Get answers to common questions about Cortef (generic hydrocortisone oral).
Yes, taking hydrocortisone with food, milk, or a light snack can significantly reduce nausea and stomach irritation. However, always take it with consistent timing—either always with food or always on an empty stomach, as directed by your doctor. This consistency helps maintain steady medication levels in your body.
Take the missed dose as soon as you remember, unless it's almost time for your next scheduled dose. Never double up on doses to make up for a missed one. If you frequently forget doses, ask your pharmacist about pill organizers or phone reminders to help you stay on track.
Yes, hydrocortisone can raise blood sugar in anyone, even those without diabetes. This effect is more pronounced with higher doses or longer use. If you have risk factors for diabetes (family history, obesity), your doctor may monitor your blood sugar periodically during treatment.
Duration depends on your condition and dose. Short-term use (days to weeks) for acute situations is generally very safe. Long-term use requires careful medical oversight and regular monitoring for side effects like bone loss, infection risk, and blood pressure changes. Your doctor will use the lowest effective dose for the shortest necessary time.
Many people experience weight gain on hydrocortisone due to increased appetite and slowed metabolism. While you can't prevent the medication's effects entirely, eating a balanced diet, limiting high-calorie foods, staying active, and managing sodium intake can help minimize weight gain. Discuss dietary strategies with your doctor or a registered dietitian.
The Bottom Line
Hydrocortisone is a potent, fast-acting corticosteroid that effectively manages inflammation and immune-related conditions ranging from adrenal insufficiency to autoimmune diseases.
