Drug Interactions between aluminum hydroxide and caffeine / pheniramine / phenylephrine / sodium citrate / sodium salicylate

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.

Alcohol can increase the nervous system side effects of pheniramine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with pheniramine. Do not use more than the recommended dose of pheniramine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Both phenylephrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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.
