HEPATOTOXIC DRUGS

Why this applies to Propylthiouracil, PTU

Propylthiouracil, PTU falls under HEPATOTOXIC DRUGS — the group Wine interacts with.

Concomitant use of alcohol with hepatotoxic drugs may increase the risk of hepatotoxicity.
Concomitant use of excessive amounts of alcohol with potentially hepatotoxic drugs can increase the risk of liver damage.
Severity Major Likelihood Probable Evidence C

Interaction 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..

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

Here's the thing about propylthiouracil (PTU): it's already one of the harder medicines on your liver. PTU carries a real risk of liver injury on its own, and wine adds another stressor to the same organ. When you regularly drink alcohol while taking PTU, you may be stacking two liver insults on top of each other, which can raise the chance of liver damage.

Watch for warning signs like yellowing of the skin or eyes, dark urine, pain in the upper right belly, unusual tiredness, or nausea, and report those right away. An occasional small glass is different from heavy or daily drinking, but please talk with your pharmacist or doctor about what's safe for you. Don't change anything on your own.

About Wine

What is Wine?

  • Social and relaxation use
  • Heart health (popular belief)
  • Antioxidant intake
  • Aiding digestion (traditional use)
  • Culinary flavoring

Wine is an alcoholic beverage made from fermented grapes and is not a true dietary supplement or medicine. Despite popular claims about heart benefits, the alcohol it contains carries real health risks, and no amount of drinking can be recommended to improve health. If you drink, do so in moderation, and avoid alcohol entirely during pregnancy or if you have certain medical conditions.

About Propylthiouracil

What Is Propylthiouracil Used For?

Brand name: Propylthiouracil

Propylthiouracil tablets are used to treat hyperthyroidism — a condition where the thyroid gland makes too much thyroid hormone. It is specifically indicated for patients with Graves' disease or toxic multinodular goiter who cannot tolerate methimazole (another antithyroid drug) and for whom surgery or radioactive iodine is not a suitable option.

It is also used to bring thyroid hormone levels under control before a patient undergoes thyroidectomy (thyroid surgery) or radioactive iodine therapy, again in patients who cannot tolerate methimazole. Because of its serious liver risks, propylthiouracil is generally a second-choice treatment — used when other options are not appropriate.
