Drug Interactions With PTU
Various beta blockers, as well as digoxin and sodium iodide I 131, are among the medications that can cause PTU drug interactions. Hyperthyroidism, which PTU is used to treat, can affect how the body handles medications, which is why it is important to tell your healthcare provider about all medicines you are taking in case the dosages need to be adjusted.
PTU (propylthiouracil) can potentially interact with several other medications. Some of the medicines that may lead to drug interactions with PTU include:
- Beta blockers, such as:
- Acebutolol (Sectral®)
- Atenolol (Tenormin®)
- Betaxolol (Kerlone®)
- Bisoprolol (Zebeta®)
