Cautions with other medicines
Some medicines do not mix well with tadalafil.
Tell your doctor or pharmacist if you're taking these medicines before you start tadalafil:
- nitrates for chest pain, such as glyceryl trinitrate (GTN)
- riociguat for pulmonary hypertension
Mixing tadalafil with herbal remedies and supplements
There are lots of treatments that claim to be a "herbal Cialis", but there is no such thing.
A herbal Cialis has never been approved as a treatment for erectile dysfunction. These treatments may also be fake or unsafe.
Some complementary therapies may have ingredients that could affect the way tadalafil works and cause side effects.
There's not enough information to say whether complementary medicines, herbal remedies and supplements are safe to take with tadalafil. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
