Always talk to your doctor before mixing Cialis with other medications. Certain drugs can significantly alter Cialis’s effectiveness or increase the risk of side effects.
Nitrates: Combining Cialis with nitrates (like nitroglycerin) can cause a dangerous drop in blood pressure, potentially leading to fainting or heart attack. This combination is strictly prohibited.
Alpha-blockers: Medications used to treat high blood pressure or enlarged prostate (e. g., tamsulosin, terazosin) can interact with Cialis, causing a sudden drop in blood pressure. Your doctor may adjust your dosages or recommend alternatives.
Other Blood Pressure Medications: Some blood pressure medications, beyond alpha-blockers, can also interact. It’s crucial to disclose all medications to your doctor to avoid potentially harmful interactions.
CYP3A4 Inhibitors: Drugs that inhibit the CYP3A4 enzyme (e. g., ketoconazole, erythromycin) can increase Cialis levels in your body, potentially increasing side effects. Your doctor might adjust your Cialis dosage.
CYP3A4 Inducers: Conversely, drugs that induce CYP3A4 (e. g., rifampin, St. John’s Wort) can reduce Cialis effectiveness. Dosage adjustments may be necessary.
HIV Protease Inhibitors: Certain HIV medications (e. g., ritonavir, indinavir) can increase Cialis blood levels, requiring careful monitoring and potential dosage modifications.
This list isn’t exhaustive, and many other drugs may interact. Always provide your doctor with a complete list of all medications, supplements, and herbal remedies you are taking before starting Cialis. This ensures your safety and optimal treatment.
