Taking Cialis 5mg with certain medications can be risky. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements.
Nitrates
Avoid nitrates (like nitroglycerin) completely. Combining them with Cialis can cause a dangerous drop in blood pressure, potentially leading to fainting or heart attack.
Alpha-Blockers
- Alpha-blockers (used to treat high blood pressure or enlarged prostate) can significantly lower blood pressure when combined with Cialis. This interaction can cause dizziness and fainting. Your doctor might adjust your dosages or recommend an alternative if you need to take both.
CYP3A4 Inhibitors
Medications that inhibit the CYP3A4 enzyme (like ketoconazole, ritonavir, erythromycin) can increase Cialis levels in your blood, potentially causing side effects. Your doctor may recommend a lower Cialis dose or an alternative treatment.
Other Medications
Guanylate cyclase stimulators (like riociguat): This combination can lead to dangerously low blood pressure. Certain antifungals (like itraconazole): These can boost Cialis levels in your blood. Some HIV protease inhibitors: Similar to antifungals, these can also increase Cialis blood levels.
Grapefruit Juice
Avoid grapefruit juice. It contains compounds that interact with Cialis’s metabolism, potentially raising its levels in your blood.
Important Note
This is not an exhaustive list. Always consult your doctor or pharmacist before mixing Cialis with other medications or supplements. They can assess potential risks and advise you on the safest approach.
