Interaction report

Vitamin A and Minocycline Hydrochloride

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Vitamin A interacts with whole categories of medication. Minocycline Hydrochloride falls into 2 of those categories, so it can interact with Vitamin A in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

HEPATOTOXIC DRUGS

1 of 2

Why this applies to Minocycline Hydrochloride

Minocycline Hydrochloride falls under HEPATOTOXIC DRUGS — the group Vitamin A interacts with.

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.
Severity Moderate Likelihood Possible Evidence C

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing minocycline and vitamin A: both can be hard on the liver on their own. Minocycline is one of the antibiotics that, in some people, can irritate the liver and raise liver enzymes. Vitamin A in high doses (above the safe upper limit) can do the same. Stacking the two could, in theory, add up and put more stress on your liver.

I want to be honest that this is based on expert reasoning, not solid proof, so don't panic. Normal food amounts and a regular daily multivitamin are very unlikely to be a problem. The risk really comes with concentrated, high-dose vitamin A. If you're taking a big vitamin A supplement, mention it to your pharmacist or doctor before continuing, and watch for things like belly pain, dark urine, or yellowing of the skin or eyes.

Moderate

TETRACYCLINE ANTIBIOTICS

2 of 2

Minocycline Hydrochloride also falls under TETRACYCLINE ANTIBIOTICS.

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing minocycline and vitamin A: both, on their own, have been tied to a rare condition called pseudotumor cerebri (also known as benign intracranial hypertension). That's basically a buildup of pressure around the brain. Putting the two together may add up and raise that risk a bit. Warning signs would be a new or worsening headache, blurred or double vision, or ringing in the ears.

The good news is that this is mostly theoretical and based on scattered case reports, not strong studies. Normal diet-level vitamin A is very unlikely to be a problem. The real caution is with high-dose vitamin A supplements, especially if you'll be on minocycline for a while (like for acne). Before adding a vitamin A pill, check with your pharmacist or doctor.

  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).

About Vitamin A

What is Vitamin A?

  • Eye and vision health
  • Skin health and acne
  • Immune support
  • Correcting vitamin A deficiency
  • Childhood growth and development

Vitamin A is an essential nutrient important for vision, skin, immune function, and growth. Most people get enough from a balanced diet, and supplements are mainly useful for correcting a true deficiency. Because vitamin A is fat-soluble and can build up to harmful levels, more is not better, and high doses are especially risky in pregnancy.

About Minocycline

What Is Minocycline Used For?

Brand names: Ximino, Minolira

Oral and intravenous minocycline products treat many serious bacterial infections, including Rocky Mountain spotted fever, respiratory tract infections, sexually transmitted infections such as lymphogranuloma venereum and nongonococcal urethritis, plague, cholera, brucellosis, tularemia, and others caused by susceptible organisms. MINOCIN Intravenous is used when oral therapy is not adequate or tolerated.

Extended-release oral minocycline tablets are indicated specifically for inflammatory lesions of moderate to severe acne vulgaris in patients 12 years and older — not for treating infections. AMZEEQ (topical foam) treats inflammatory lesions of moderate to severe acne vulgaris in patients 9 years and older. ZILXI (topical foam) and EMROSI (oral capsule) are indicated for inflammatory lesions of rosacea in adults. ARESTIN (oral powder placed by a dental professional) is used alongside scaling and root planing to reduce pocket depth in adult periodontitis.
