Hydrocortisone val. It is used for inflammatory conditions in the skin. There are many types of Hydrocortisone and all of them have varying strengths. Your doctor will choose the one deemed best to help your problem.
No. Hydrocortisone valerate is a mid potency steroid that works on some rash types. I would be careful using it on rashes that your doctor has not diagnosed, as it can make certain rashes worse (i.E infectious).
Not the same. Steroids are classified based on strength or potency. Class 1 to 7 (high to low). For the same prescription ointments are stronger than cream. Also the percentage of ingredient in the medication does not always correlate with the strength of the steroid. So the difference between Hydrocortisone 1% (class 7-least potent) and Hydrocortisone valerate (class 4/5-mid strength) is potency.
Strength. Steroids are classified from 1-6. Hydrocrtisone is weak. The value rate version is much stronger and should not be sued in sensitive areas such as face, armpits or groin. It will thin the skin and potentially cause stretch marks with extended use.
Weird prescription. It doesn't sound strange. It is good practice to get all of your questions answered fully before you leave your doctor's office. If he or she doesn't want to answer them, find someone else quick. If you have questions when you get home, call them and give them 24h to get you an answer. Your own personal doctor is your best source of information.
It can help. Due to its antiinflammatory properties. Anusol has a topical anesthetic and is usually for the gums and in combo may add some additional relief. Oral pain meds, aleve or ibuprofin are also winners. Consider MiraLAX (polyethylene glycol) to prevent constipation which always makes hemmorroids worse. Goog ole preperation h is a good, inexpensive combination.
