Interactions between your drugs

Moderate

doxycycline aluminum hydroxide

Applies to: doxycycline and Gaviscon Extra Strength (aluminum hydroxide / magnesium carbonate)

Doxycycline and aluminum hydroxide should not be taken orally at the same time. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of doxycycline into the bloodstream and reduce its effectiveness. If possible, it may be best to avoid taking aluminum hydroxide while your are being treated with doxycycline. Otherwise, you should separate dosing by 2 to 4 hours, doxycycline should be taken at least 2 hours before and not less than 6 hours after Suprep Bowel Prep (magnesium/potassium/sodium sulfates), or doxycycline and aluminum hydroxide should be taken as directed by your healthcare provider. Talk to your healthcare provider if you are unsure whether your medications contain something that could potentially interact or if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug and food interactions

Major

aluminum hydroxide food

Applies to: Gaviscon Extra Strength (aluminum hydroxide / magnesium carbonate)

Citrate, or citric acid, can increase the absorption of aluminum hydroxide. This may lead to elevated blood levels of aluminum, particularly in individuals with reduced kidney function, since aluminum is primarily eliminated by the kidneys. Excess aluminum may deposit and cause problems in various tissues including bone, brain, heart, liver, muscles, and spleen. Over time, weak bones, bone pain, fractures, skeletal deformity, brain disorders, and anemia may develop. Talk to your doctor before using aluminum hydroxide if you have kidney impairment or are on hemodialysis. You should avoid or limit the consumption of citrate-containing foods and beverages (e.G., soft drinks, citrus fruits, fruit juices) during treatment with aluminum hydroxide. Be aware that some effervescent and dispersible drug formulations may also contain citrate and should be restricted as well. Even if you do not have kidney problems, it may be best to separate the dosing of aluminum hydroxide and citrate-containing products by 2 to 3 hours. Talk to a healthcare professional if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

When aluminum hydroxide is taken during enteral nutrition therapy (tube feeding), the tube may get clogged. Therefore, aluminum hydroxide should not be mixed with or given after high-protein tube feedings. The dose should be separated from the feeding by as much as possible, and the tube should be thoroughly flushed before administration of the dose.

Moderate

doxycycline food

Applies to: doxycycline

Iron can bind to doxycycline in the gastrointestinal tract, which may prevent their absorption into the bloodstream and possibly reduce their effectiveness. To avoid or minimize the interaction, iron-containing medications and doxycycline should preferably be taken at least three to four hours apart in most cases. Talk to your doctor if you have any questions or concerns, or if you have trouble separating the dosing times. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
