Serious Warnings

Minocycline can cause serious side effects. It can cause increased pressure inside the skull, called pseudotumor cerebri. Stop taking minocycline and tell your doctor right away if you have a headache, vision problems, or dizziness. Minocycline can also damage kidneys. Tell your doctor if you notice decreased urination, swelling in your feet or ankles, or fatigue.

Known Drug Interactions

Drug Interactions Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracycline-class drugs in conjunction with penicillin. Absorption of tetracyclines is impaired by antacids containing aluminum, calcium, or magnesium, and iron-containing preparations.

Mechanism: Both of these medications are in the same antibiotic family and work the same way. Taking them together increases the risk of side effects without helping to fight the infection any better.

What to do: Avoid taking these two antibiotics at the same time. Your doctor should prescribe only one medication from this class.

Administration of isotretinoin should be avoided shortly before, during, and shortly after minocycline therapy.

Mechanism: Using these drugs together can increase the risk of dangerous pressure building up inside the skull.

What to do: Do not take these two medications at the same time or within a short period of each other.

This is a plain-language summary of interactions documented in FDA labeling, not individualized advice. Ask a pharmacist or prescriber before combining medications.
