Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies, before starting Viagra. This includes nitrates, commonly used for chest pain. Combining them with Viagra can cause a dangerous drop in blood pressure.
Alpha-blockers, often prescribed for high blood pressure or prostate problems, can also interact negatively with Viagra, potentially leading to low blood pressure and dizziness. Your doctor might adjust your dosages or suggest alternatives.
Certain antifungal medications, such as ketoconazole and itraconazole, can increase Viagra’s levels in your blood, potentially raising the risk of side effects. Similarly, some HIV protease inhibitors can have a similar effect.
Blood thinners like warfarin can interact with Viagra, although this interaction is less predictable and requires close monitoring by your physician. A dosage adjustment might be necessary.
Grapefruit juice inhibits enzymes that metabolize Viagra, leading to higher blood levels and increased risk of side effects. Avoid grapefruit juice while taking Viagra.
