FAQ

What is Vibramycin-D?

Vibramycin-D is an oral antibiotic that can treat recurrent aphthous mouth ulcers. It’s in a group of drugs called tetracyclines, which kill bacteria by inhibiting the production of proteins.

Mouth ulcers, also known as canker sores, are white inflamed spots that form in your mouth. They can be caused by many things, like hormonal changes or irritation, and often cause discomfort and pain.^[1]

How does Vibramycin-D work?

Doxycycline, the active ingredient in Vibramycin-D, is what’s known as a tetracycline. These drugs bind to bacterial ribosomes (the component that makes protein) to stop protein production.^[2] Without proteins, bacteria can’t grow, which leads to their eventual death.

It also has additional benefits beyond just being an antibiotic. It has anti-inflammatory properties, which can help reduce swelling by suppressing the action of inflammatory cells. And it can help with tissue damage and the healing of your ulcer, as it has anti-collagenase properties. Collagenase is an enzyme that breaks down tissue. Inhibiting its actions can reduce pain and help speed up the healing process.^[3]

What doses of Vibramycin-D are there?

Although you can get different doses of doxycycline, Vibramycin-D is only available in 100mg strengths. Vibramycin-D differs slightly from other doxycycline tablets. It’s a dispersible tablet which dissolves when mixed with water. This way, you can use it as a mouth rinse.

FAQ: Vibramycin-D

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

Does Vibramycin-D have side effects?

Answer:

As with all medicines, Vibramycin-D can cause side effects for some people. But since you aren't swallowing the tablet, it's less likely you’ll get them. Common side effects include:

feeling or being sick;

inflammation affecting the heart;

heartburn;

vaginal infection; or:

worsening of a disease called systemic lupus erythematosus (SLE).

For more information on the side effects, check the patient information leaflet.

How does Vibramycin-D compare with other treatments for mouth ulcers?

Answer:

Vibramycin-D is a good treatment if you suffer from recurrent mouth ulcers. It has antimicrobial and anti-inflammatory properties, which help stop ulcer formation. However, in some cases, recurrent mouth ulcers can be a sign of vitamin B deficiency, so your clinician might suggest you take Cyanocobalamin to boost your vitamin B levels.

Although mouth ulcers don't always need treatment, your clinician might suggest using an antiseptic mouthwash like Corsodyl if you’re finding it irritating and it’s making it difficult for you to eat and drink.

Whereas if you only get painful ulcers now and then, Benzydamine might be the best option for you. It’s a non-steroidal anti-inflammatory spray that works almost instantly to relieve pain and swelling. If you have a stubborn ulcer, you might be prescribed steroids, like Beclomethasone dipropionate, which help reduce swelling and pain.

Can I take Vibramycin-D if I'm pregnant or breastfeeding?

Answer:

Don't take Vibramycin-D when you’re pregnant or breastfeeding. Doxycycline can affect tooth development and cause discolouration of the teeth in children and babies.

Can I drink alcohol when taking Vibramycin-D?

Answer:

It’s best that you avoid alcohol while taking Vibramycin-D. This is because it can limit its effectiveness and make the healing process last longer. So it’s best to wait till after your treatment is over to have a drink if you want to get the best from it.
