Cialis side effects

Cialis is a medication that blocks the effects of phosphodiesterases, which are the chemicals that would drain blood from the penis and cause a man to lose an erection. However, while blocking one type of phosphodiesterase can help with erections, blocking another type of phosphodiesterase can cause side effects. Also, any drug has a lengthy list of potential unwanted effects and erectile dysfunction drugs are no exception. Cialis is a phosphodiesterase inhibitor and, while generally safe, side effects are possible (even very severe life threatening ones). A phosphodiesterase inhibitor was developed as a blood pressure medication long before it was used to treat erectile dysfunction. In some situations, it can cause dangerously low blood pressure. That is why doctors ask about other medications that can lower blood pressure, especially nitrites/nitrates. Nitrites/Nitrates (found in nitroglycerin and other medications, as well as recreational “poppers”) are so dangerous that their use is an absolute contraindication to prescribing or using Cialis. Another possible side effect of using phosphodiesterase inhibitors can be a change in vision, including blue tinted vision. This is much less of an issue with Cialis. However, while rare, it is possible for people using phosphodiesterase inhibitors, including Cialis, to suffer complete, permanent blindness in one or both eyes. If this happens, go immediately to an emergency room. It does not matter if it is rare if it happens to you. Be prepared to act immediately if your vision is affected. Sometimes, Cialis works too well and an erection can last far longer than it should. If the penis remains engorged (priapism) it can be painful but, more importantly, the tissue and vessels of the penis can be damaged (even permanently). If you have an erection lasting longer than 4 hours, painful or not, seek immediate medical attention. To one degree or another, all the medicines used to treat ED cause side effects that include: headaches (10%-16%), nasal stuffiness (1%-10%), flushing (5%-12%), dizziness (~3%), and upset stomach (4%-12%). [Drugs 2005;65:1621-1650] The most common side effects of Cialis include: headache, dyspepsia (i.e., pain or an uncomfortable feeling in the upper middle part of your stomach), back pain, myalgia (i.e., muscle pain), nasal congestion, flushing, and pain in limb. This list is incomplete and the PDR contains a great deal of information of a lengthy list of potential side effects, as well as warnings and contraindications. Please read the list. It is the best way to be prepared and recognize issues that should be addressed emergently.
