Interactions with Other Medications

Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and recreational drugs, before starting tadalafil. This is crucial for preventing potentially harmful interactions.

Nitrates

Tadalafil should never be taken with nitrates, such as nitroglycerin. This combination can cause a dangerous drop in blood pressure, leading to serious complications.

Alpha-Blockers

Using tadalafil with alpha-blockers (used to treat high blood pressure or enlarged prostate) may significantly lower blood pressure. Your doctor may adjust your dosage to minimize this risk.

CYP3A4 Inhibitors

    Ketoconazole Erythromycin Ritonavir

These medications can increase tadalafil levels in your blood, potentially leading to side effects. Your doctor may recommend a lower dose of tadalafil or an alternative treatment.

CYP3A4 Inducers

    Rifampin St. John’s Wort

These medications can decrease tadalafil levels, reducing its effectiveness. Your doctor may need to adjust your dosage or prescribe a different medication.

Alcohol

While moderate alcohol consumption is usually acceptable, excessive alcohol use can increase the risk of side effects with tadalafil, such as dizziness and headache. Avoid excessive alcohol intake while using this medication.

Grapefruit Juice

Grapefruit juice can also interfere with tadalafil metabolism. Limit or avoid grapefruit juice while taking this medication.

Other Medications

Other medications may interact with tadalafil. Provide your doctor with a complete list of your medications to assess potential interactions and ensure your safety.
