Are there dosage adjustments due to medical conditions or interactions?
There are several factors that may require an adjustment to your Cialis dosage. These include kidney, liver and drug interactions, as detailed below.
Dosage for people with kidney problems
Cialis is partially excreted from the body via the kidneys. Therefore, people with kidney problems are more likely to experience side effects from Cialis because the drug can build up in the body. In this case, you may need to take a lower dose.
If you have kidney problems, your doctor may do a blood testCreatinine-clearance(CrCl) to assess how well your kidneys are working. This usually determines your dose of Cialis.
