Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and recreational drugs. Cialis Black 200mg can interact negatively with several substances, potentially leading to adverse effects.
Nitrates and Nitroglycerin
Combining Cialis Black 200mg with nitrates, such as nitroglycerin used for chest pain, can cause a dangerous drop in blood pressure, potentially leading to fainting or even a heart attack. This combination is strictly contraindicated.
Alpha-Blockers
Alpha-blockers, commonly prescribed for high blood pressure or enlarged prostate, can enhance the blood pressure-lowering effects of Cialis Black 200mg. This combination may increase the risk of dizziness and fainting. Your doctor should carefully monitor your blood pressure if you’re taking both.
CYP3A4 Inhibitors
Medications that inhibit the CYP3A4 enzyme, such as ketoconazole and ritonavir, can increase Cialis Black 200mg levels in your blood, potentially intensifying side effects. Your doctor may need to adjust your Cialis Black 200mg dosage.
