Do not take Cialis if you:

• take any medicines called "nitrates".
• use recreational drugs called "poppers" like amyl nitrite and butyl nitrite.
• take any medicines called guanylate cyclase stimulators, such as riociguat.
• are allergic to Cialis or Adcirca, or any of its ingredients.

Call your healthcare provider or get help right away if you have any of the symptoms of an allergic reaction listed above.

Stendra may interact with nitrates, alpha blockers, antihypertensives, alcohol, ketoconazole, ritonavir, antibiotics, and amlodipine. Tell your doctor all medications you use.

Take Cialis exactly as your healthcare provider prescribes it. Your healthcare provider will prescribe the dose that is right for you.

Some men can only take a low dose of Cialis or may have to take it less often, because of medical conditions or medicines they take.

Do not change your dose or the way you take Cialis without talking to your healthcare provider. Your healthcare provider may lower or raise your dose, depending on how your body reacts to Cialis and your health condition.

Cialis may be taken with or without meals.

If you take too much Cialis, call your healthcare provider or emergency room right away.

For most patients, the starting dose is 100 mg taken approximately 30 minutes before sexual activity, on an as needed basis. Stendra should not be taken more than once per day. The dose may be increased to 200 mg or decreased to 50 mg based on efficacy and/or tolerability, however, it is best to use the lowest beneficial dose.
