It is now possible to buy Doryx in generic form. The generic versions come in three strengths and are made by Mylan Pharmaceuticals and other manufacturers. All of the generic forms of Doryx have been assigned an "AB" rating by the FDA. This means they are considered equivalent to the brand-name version; however, they are allowed to contain different inactive ingredients.
Doryx® (doxycycline hyclate delayed release) is a prescription medication approved for treating and preventing a variety of different infections. It is the only doxycycline medication that contains delayed-release pellets in a tablet. It is usually taken just once a day.
Currently, brand-name Doryx is made by Mayne Pharma International Pty. Ltd., for Warner Chilcott (US), LLC. However, the medication is also available in generic form.
Generic Doryx is available in the following strengths:
- Doxycycline hyclate 75 mg delayed-release tablets
- Doxycycline hyclate 100 mg delayed-release tablets
- Doxycycline hyclate 150 mg delayed-release tablets.
Generic Doryx is made by various manufacturers, such as Mylan Pharmaceuticals and Impax Laboratories.
All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one.
An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic Doryx versions currently available have an "AB" rating, meaning they should be equivalent to Doryx.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
