Nasal congestion
Lower back pain (unique to Cialis)
Visual disturbance (eg, blurred vision, increased light sensitivity, persistence of a bluish tinge, temporary loss of the ability to distinguish between blue and green)
Your physician will determine which of these medications is most appropriate for you and the optimal dosage. Never give any of these medications to anyone else as they can cause serious problems due to drug interactions if not monitored by a physician.
Medications, such as ketoconazole (an antifungal medication known as Nizoral), erythromycin (an antibiotic), and cimetidine (a drug to reduce stomach acid known as Tagamet), can interfere with the chemical processing of medications like Viagra by the liver.
Alpha-blocker type medications (eg, Hytrin, Cardura, Uroxatral, Flomax) may have potentially dangerous interactions with Viagra, Levitra, and Cialis. If you are taking any of these medications, check with your physician or pharmacist about potential drug interactions.
Certain street drugs (eg, ecstasy) can also cause serious problems if taken with Viagra, Levitra, or Cialis.
Viagra, Levitra, and Cialis should absolutely not to be taken by:
Men with heart conditions who are taking nitrates, such as nitroglycerine (Combining Viagra, Levitra, or Cialis with nitrate-based medications can cause a severe and dramatic drop in blood pressure with potentially very dangerous consequences.)
Men with serious heart disease or exertional angina (chest pain)
Men who are taking multiple drugs for high blood pressure
Yohimbine
Yohimbine, an herbal product, comes from the bark of a West African tree. Its use in treating erectile dysfunction is questionable, and, in studies, yohimbine is only slightly better than placebo (no drug at all).
Nonetheless, yohimbine is considered safe with few known side effects. The usual daily dose is a 5.4-mg tablet taken 3 times a day.
