Periostat is a low-dose doxycycline medicine used with professional periodontal care in adults with periodontitis, also called advanced gum disease. You can buy Periostat online and choose the strength and quantity shown during ordering so the product matches the directions from your dental clinician. The commonly referenced presentation is Periostat 20 mg tablets, a subantimicrobial doxycycline dose used for gum-support therapy rather than a standard infection course.
Periostat dental therapy is typically used after scaling and root planing, the deep-cleaning procedure that removes plaque and tartar below the gumline. The medicine does not replace brushing, flossing, dental cleanings, or periodontal follow-up, but it may be part of a broader plan to help improve tooth attachment and reduce gum pocket depth progression.
Periostat Price and 20 mg Tablet Choices
The periostat price shown at checkout depends on the strength, tablet form, and quantity chosen. Periostat 20 mg is the important strength to match when the treatment plan calls for low-dose periodontal doxycycline. A different doxycycline strength may share the same active ingredient, but it can be intended for a different medical purpose.
Periostat cost can also change with the supply quantity. A larger number of tablets may increase the total amount due, while the per-tablet comparison may look different across quantities. For cash-pay planning, look at the full quantity, the strength, and the expected dosing schedule together instead of comparing only the product name.
If you are considering Periostat without insurance, keep your dental paperwork and current medication list nearby while ordering. That helps you match the tablet strength and quantity to the dental plan already discussed with your clinician. Do not substitute another doxycycline product unless the clinician managing your periodontal care has changed the plan.
Quick tip: Match strength, tablet form, and quantity first; then compare the total cost.
How to Order Periostat Online
To order Periostat online, start with the product name and the Periostat 20 mg tablet strength commonly used for periodontal therapy. During ordering, choose the quantity that fits the directions you were given and check that the active ingredient is doxycycline hyclate. Small differences in strength or form can matter with doxycycline products.
BorderFreeHealth offers cross-border access through licensed pharmacy channels for U.S. customers paying cash for medications. Service wording such as US delivery from Canada describes the order and travel route, not a guaranteed arrival date. If prompt, express shipping appears during checkout, it is a logistics choice and does not change storage or safety requirements for the medicine.
Once the medication arrives, read the bottle label and any auxiliary warning stickers before the first dose. Labels may include important directions about fluids, mineral supplements, sunlight, and timing. If the label differs from what you expected, ask a pharmacist or dental clinician before starting the bottle.
What Periostat Is Used For
Periostat is used in adults with periodontitis after scaling and root planing. Periodontitis is advanced gum disease in which inflammation and bacterial plaque contribute to gum pocketing, loss of attachment, and possible tooth-support damage. Periostat is used as an adjunct, meaning it works alongside professional dental treatment rather than standing alone.
The medicine contains doxycycline hyclate, but its periodontal use is different from higher-dose doxycycline used for infections. Periostat doxycycline 20 mg is described as a subantimicrobial doxycycline dose. In plain terms, it is used at a low dose to affect enzymes involved in gum tissue breakdown, not to act like a typical short antibiotic course for an acute infection.
This distinction answers a common question: Periostat is related to doxycycline because it contains doxycycline hyclate, but not every doxycycline product is the same as Periostat. Doxycycline 50 mg, 100 mg, capsules, tablets, or delayed-release forms may have different uses and instructions. The active ingredient name alone should not be used to decide whether two products are interchangeable.
For condition-based browsing, the Periodontitis collection groups products connected with advanced gum disease. The Oral Health category is useful when you want to browse dental and mouth-care products more broadly.
Strength, Form, and Label Details
Periostat is commonly supplied as 20 mg tablets for oral administration. The label may identify the active ingredient as doxycycline hyclate and may include warnings about taking the tablet with enough water, separating it from minerals, and protecting your skin from sun exposure. Treat the dispensed label as the most specific source for the exact manufacturer description.
When comparing periostat 20 mg cost with another doxycycline item, verify that the other product is also a 20 mg tablet intended for periodontal therapy. Higher-strength doxycycline products can be appropriate for other conditions, but they should not be treated as a direct replacement for low-dose periodontal dosing. Household mix-ups are more likely when multiple doxycycline bottles are stored together.
| Detail | What to match | Why it matters |
|---|---|---|
| Strength | 20 mg | Identifies the low-dose periodontal presentation |
| Form | Tablet | Helps distinguish it from capsules or other formulations |
| Ingredient | Doxycycline hyclate | Supports allergy and interaction screening |
| Quantity | Amount chosen during ordering | Affects total cost and supply length |
Keep Periostat tablets in the original labeled container. This makes the strength, ingredient, lot information, and directions easy to identify. It also lowers the chance of confusing a low-dose periodontal tablet with another doxycycline medicine kept in the same home.
Dosage and How to Use the Tablets
The commonly labeled periostat dosage is one 20 mg tablet twice daily, about 12 hours apart, as an adjunct to scaling and root planing. Many references describe morning and evening dosing. Your own bottle label and dental clinician’s instructions should guide timing and duration.
Periostat 20 mg dosage instructions often emphasize swallowing the tablet with an adequate amount of fluid. Doxycycline can irritate the esophagus, the tube between the mouth and stomach, especially if taken with too little water or if you lie down soon afterward. Remaining upright after a dose may help reduce that discomfort.
Mineral-containing products can reduce doxycycline absorption. Calcium, magnesium, aluminum, iron, and zinc may appear in antacids, multivitamins, supplements, laxatives, and some fortified products. Ask a pharmacist how to space these products from Periostat rather than guessing, because spacing instructions can depend on the specific product.
The duration of Periostat therapy can vary by periodontal plan. Labeled and reference materials commonly describe use for a limited treatment period under professional supervision. Keep follow-up appointments so gum measurements, plaque control, and tissue response can be assessed while the medicine is being used.
Why it matters: Consistent timing and follow-up help the medication fit the dental treatment plan.
Storage, Travel, and Handling
Store Periostat tablets at controlled room temperature, away from excess heat, moisture, and direct light. Bathrooms and parked cars are poor storage locations because humidity and temperature can change quickly. Keep the cap tightly closed and leave the label on the bottle for reference.
When traveling, keep the medication in hand luggage when possible. Checked bags can be delayed or exposed to temperature changes, and losing the bottle can interrupt an established routine. If you use a pill organizer, keep the original container nearby so the tablet strength and ingredient remain identifiable.
Do not use tablets that appear damaged, unusually discolored, or exposed to poor storage conditions. If a bottle has been left in heat or moisture, ask a pharmacist whether it should still be used. Doxycycline products should also be kept out of reach of children and away from other household medicines that look similar.

Side Effects, Warnings, and Interactions
Periostat can cause side effects similar to other doxycycline products, even though it is used at a lower periodontal dose. Common effects may include nausea, upset stomach, diarrhea, headache, and increased sensitivity to sunlight. Sun sensitivity can make sunburn more likely, so protective clothing and sunscreen are practical precautions outdoors.
Esophageal irritation is an important doxycycline warning. Throat pain, chest discomfort, or a sensation that a pill is stuck can occur if the tablet is taken with too little fluid or close to lying down. Follow the bottle’s fluid and timing instructions, and seek medical advice if swallowing pain or chest discomfort persists.
Serious reactions need prompt attention. Seek urgent help for hives, facial swelling, trouble breathing, a widespread rash, or other signs of a severe allergic reaction. Persistent severe diarrhea, especially with abdominal cramping or fever, should also be assessed because antibiotics can sometimes be associated with C. difficile diarrhea.
Doxycycline products are generally avoided during pregnancy because tetracyclines can affect fetal tooth and bone development. They are also generally not recommended for young children, commonly under age 8, because of the risk of permanent tooth discoloration. Breastfeeding, liver disease, repeated yeast infections, or a history of severe medication reactions should be discussed with a healthcare professional.
Medication and supplement interactions matter before starting doxycycline periostat therapy. Important items to mention include warfarin or other anticoagulants, isotretinoin or related retinoids, seizure medicines, antacids, iron, zinc, magnesium, calcium, and multivitamins. Alcohol use and liver conditions may also affect safety discussions.
Periostat is not intended to treat urgent dental infections on its own. Fever, spreading facial swelling, severe tooth pain, trouble swallowing, or difficulty breathing can signal a dental or medical emergency. Low-dose periodontal doxycycline is different from treatment chosen for an acute infection.
Dental Follow-Up and Treatment Expectations
Periostat works best as part of a periodontal plan that includes professional cleaning, home plaque control, and scheduled reassessment. Scaling and root planing remove bacterial deposits below the gumline; medication may support the tissue response after that procedure. Brushing, interdental cleaning, and follow-up measurements remain essential.
People often ask how long Periostat can be taken. The answer depends on the dental plan, gum measurements, response to treatment, and tolerability. Do not extend, stop, or restart Periostat based only on symptoms, because periodontitis can progress quietly even when pain is not present.
Track questions between visits so your dental team can address them efficiently. Useful topics include missed doses, stomach upset, sun exposure, supplement spacing, changes in gum bleeding, and any new medicines started during therapy. Practical monitoring helps keep the medicine aligned with the larger periodontal treatment goal.

Comparing Related Doxycycline Products
Periostat should be compared by purpose, strength, and form. Its 20 mg tablet presentation is associated with periodontal adjunct therapy, while many other doxycycline products are prescribed at higher strengths for infections or other conditions. Similar names can create confusion, so match the exact strength and dosage form before making a product decision.
The term periostat antibiotic can also be confusing. Periostat contains doxycycline, an antibiotic-class ingredient, but the 20 mg periodontal dose is described as subantimicrobial. That means the dose is lower than typical antimicrobial treatment doses and is used for host-response modulation in gum disease care.
If your dental paperwork mentions doxycycline but does not specify Periostat, do not assume that any doxycycline 20 mg tablets or higher-strength doxycycline product is equivalent. Ask the clinician managing your gum disease whether the intended medicine is the branded low-dose periodontal tablet, a related doxycycline product, or a different plan entirely.

What is Periostat used for?
Periostat is used in adults with periodontitis after scaling and root planing. It is an adjunct treatment, meaning it supports professional periodontal care but does not replace dental cleanings, home oral hygiene, or follow-up gum measurements.
Is Periostat the same as doxycycline?
Periostat contains doxycycline hyclate, but it is not the same as every doxycycline product. Periostat 20 mg tablets are used as a low-dose, subantimicrobial doxycycline option for periodontal therapy, while other doxycycline strengths or forms may be used for different conditions.
Has Periostat been discontinued?
Periostat is presented here as a product that can be ordered. If you have seen discontinuation comments from a different market or pharmacy, focus on the product strength, form, and current ordering information shown during checkout, and ask a pharmacist if you need help matching it to your dental plan.
How long can you take Periostat?
Duration depends on the periodontal treatment plan and your response to therapy. Reference materials commonly describe Periostat use for a limited course under dental supervision. Follow the bottle label and your dental clinician’s instructions rather than extending or restarting it on your own.
What side effects can Periostat cause?
Common side effects may include nausea, upset stomach, diarrhea, headache, and sun sensitivity. Seek medical help for allergic reactions, severe rash, breathing trouble, facial swelling, or persistent severe diarrhea with cramps or fever.
Can minerals or supplements affect Periostat?
Yes. Calcium, magnesium, aluminum, iron, and zinc can interfere with doxycycline absorption. These minerals may be found in antacids, multivitamins, supplements, and some laxatives, so ask a pharmacist how to separate them from Periostat.
