What is Preparation H?

American Home Products (AHP) is the leading company that manufactures the product. Different formulations have been made to the product, including water-based gel, petroleum, or jelly-based and suppositories. It contains a wide range of different active ingredients, from simple caffeine moisturizer. 

In the preparation of some products under Preparation H, some have active phenylephrine, a substance that constricts the blood vessels. It is also more commonly used as a decongestant. It works by restricting the blood flow in the nasal areas and passages and will decrease the amount of mucus and the liquid flow it creates when you are experiencing runny noses. 

Since hemorrhoids are mainly caused by the blood vessels that are inflamed, it restricts the blood flow and reduces the swelling size, which reduces the pain and the discomfort you are feeling. 

Also, a different version of Preparation H contains hydrocortisone with its only active ingredient. Hydrocortisone is a substance that visibly reduces swelling and inflammation. 

There is also a Canadian formulation of the drug Preparation H that contains yeast extract known to be BioDyne. This extract is believed to have a good effect on your skin, including wrinkle removal, and moisturizing dry and irritated skin. Meanwhile, other subsidiary products may contain protective barriers like cocoa butter, hard fat, mineral oil, and shark liver oil that help prevent too much irritating skin when in contact with the stool.

If you are using the ointment kind, it is necessary to cleanse the affected area before applying the ointment. You can pat or blot the area with a cleansing wipe and gently dry pat it with a tissue or clean, soft cloth. Only after cleansing should you put the ointment. This should be applied to the affected area on an average of 4 times daily, especially during the night, in the morning, and every after-bowel movement. 

For intrarectal use or inside the rectum area, you have to detach the cover from the applicator, then attach the applicator to the tube, lubricate the applicator properly and then gently insert the applicator inside the rectum. Do not forget to also apply the ointment in the outer part of the rectum. The regular use of the ointment continuously provides therapy for the relief of symptoms.

For the application of maximum strength cream, just like with the ointment, you have to clean the affected area first with a clean cloth or cleansing wipes. Then apply externally on the lower area of the anal canal or to the affected area, up to four times a day, especially during the nighttime, in the morning, and every after-bowel movement. 

If you are using suppositories to treat your hemorrhoids, you will experience an entirely different process. After cleansing the affected area, you will not apply anything. Instead, you will need to insert the suppository. You have to detach one suppository from the other on the strip, then remove all the foil wrapper before you insert it in your rectum. It would help if you held the suppository down with the rounded end up, carefully separate the foil tabs by inserting the tip of your fingernail at the end of the foil that is marked “peel down,” and then slowly and evenly peel apart the foil by pulling the tabs down to both sides, until suppository is exposed.
