The patents for Vibramycin have expired and there are generic versions of this medication available. Generic Vibramycin is available in the form of capsules (50 mg and 100 mg) and as a powder used to make an oral suspension (25 mg per 5 mL). The FDA has assigned all generic versions an "AB" rating, meaning they should be equivalent to the brand-name medication.
Vibramycin® (doxycycline) is a prescription medication approved for treating and preventing a variety of different infections. Vibramycin belongs to a group of antibiotics known as tetracyclines. It comes in three different forms (capsules, syrup oral suspension, and powder for oral suspension). The syrup oral suspension comes in ready-to-use form, while the powder for oral suspension must be mixed by your pharmacist.
Brand-name Vibramycin is manufactured by Pfizer, Inc. However, it has come off patent and is available as a generic.
Generic Vibramycin is available in the following strengths and forms:
- Doxycycline hyclate 50 mg capsules
- Doxycycline hyclate 100 mg capsules
- Doxycycline 25 mg per 5 mL powder for oral suspension.
Vibramycin 50 mg per 5 mL syrup oral suspension is currently unavailable in generic form.
Generic Vibramycin is made by a few different companies, such as:
- Mutual Pharmaceutical Co., Inc.
- Teva Specialty Pharmaceuticals
- Watson 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 each generic a rating. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic Vibramycin versions currently available have an "AB" rating, meaning they should be equivalent to Vibramycin.
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.
It should also be noted that there are several other brand-name and generic doxycycline medications available that are not equivalent to Vibramycin.
