Can I take a 150mg ranitidine and a 2mg Xanax (alprazolam) together safely and will the ranitidine affect the absorption of the xanax (alprazolam)? Thank You

Can I take a 150mg ranitidine and a 2mg Xanax (alprazolam) together safely and will the ranitidine affect the absorption of the xanax (alprazolam)? Thank You

No interactions: Or differences in absorption with ranitidine and alprazolam. You don't list Xanax on your medications, and 2 mg is a hefty dose of this very potent drug. This would be a dose that someone would have been built up to if lower doses didn't work. The starting dose of Xanax should be about 0.5 mg if you have not been on it before. If it is prescribed for you, your doctor/pharmacist can advise you.

Just started taking Caltrate. Will Zantac interfere or block absorption of Caltrate?

Just started taking Caltrate. Will Zantac interfere or block absorption of Caltrate?

It may: Interfere with the "sticking" on the inflammed lining of your stomach...ACID causes the inflammation so in a way you are taking two medicines with opposite mechanisms of action! Speak with your PCP (I assume you are taking these medications under medical supervision...if not get some! Hope this helps Dr Z

Apart from ppis is there any other food or drugs that may affect calcium absorption?

Apart from ppis is there any other food or drugs that may affect calcium absorption?

Foods: Phytic acid and oxalic acid, found naturally in some plants, bind to calcium and can inhibit its absorption. Foods with high levels of oxalic acid include spinach, collard greens, sweet potatoes, rhubarb, and beans. Eating spinach and milk together reduces calcium absorption. Foods high in phytic acid include whole-grain products and wheat bran, beans, seeds, nuts, and soy isolates.

Do calcium supplements interfere with the absorption of some medications?

Do calcium supplements interfere with the absorption of some medications?

Yes.: They can significantly lower the amount of thyroid hormone that gets absorbed. Because calcium is a positively charged ion, it can bind to any negatively charged chemical, including levothyroxine. Spacing the thyroid hormone at least 2 hours from calcium (including antacids such as tums), iron, multi-vitamins, and certain other meds can help keep thyroid blood levels stable.

For 55+ female, does high VitD & calcium dosage directly or indirectly intervene with Iron absorption from food?

For 55+ female, does high VitD & calcium dosage directly or indirectly intervene with Iron absorption from food?

Calcium and iron: calcium supplements can interfere with iron absorption from the diet. Normally, this is insignificant and usually does not cause iron deficiency. If someone is bound to be iron deficient, the first step is to rule out loss of iron in the form of obscure bleeding from the digestive tract. It is vitally important to rule this out first. Good luck.
