Cialis: Uses, Side Effects and Drug Interactions

For male patients who want to start taking Cialis, there are certain things that should be learnt about this famous and effective ED medicine. It’s available in different strengths, from 2.5 to 20 mg, and its intake may interact with some other drugs or result in side effects, so you need to learn this important information.

Mechanism of Action

Cialis is an oral medication taken to treat erectile dysfunction and BPH, and it belongs to a group of drugs called PDE-5 inhibitors. It works by preventing PDE-5 from ruining cGMP, thus, ensuring stronger and more lasting erections. When it comes to treating BPH symptoms, the exact mechanism of this medicine is unclear, but there are suggestions that it relaxes muscles in the urethra.

Important Warnings

The use of Cialis is associated with priapism, or prolonged erection, so that you need to go to the hospital once you experience any associated symptoms. Besides, this medication taken by those patients who have pre-existing heart problems is rarely associated with the following health complications:

• Heart attacks and strokes;
• Irregular heart rates;
• Palpitations and chest pain.

In rare cases men may lose hearing suddenly or experience dizziness and ringing in their ears in addition to unexpected vision problems.

Possible Side Effects

When taking Cialis, some male patients may experience certain adverse effects, but the good news is that most of them are rare and stop fast. The most common side effects associated with this ED medicine include:

• Headaches;
• Nausea and vomiting;
• Facial reddening and rash;    
• Hypotension;
• Vision changes;
• Diarrhea and stomach upset.

Besides, the components of Cialis may result in allergic reactions, so that you need to call your doctor once you notice any relevant symptoms, such as drowsiness, dizziness, coughing, etc.

Drug Interactions

There are certain drugs that shouldn’t be taken with Cialis if you don’t want to end up with dangerous combinations. For example, they include ketoconazole, ritonavir, erythtomycin, indinavir and some others, because they increase the level of its active ingredient in the blood. Such meds as phenytoin, rifampin and carbamazepine may decrease its levels, and you shouldn’t combine them.

It’s not allowed to combine Cialis with nitrates and alpha-blockers to avoid negative reactions and serious side effects. Patients are not advised to combine this medication with alcoholic beverages because they risk ending up with headaches, hypotension, dizziness, irregular heart rates and other unwanted adverse effects. If you have ulcers or bleeding disorders, you should be careful with the intake of Cialis, too.

Recommended Doses

Most male patients are recommended to start taking this ED medicine with 10 mg taken at least 30 minutes before their planned sexual intercourse. Their dose can be both reduced and increased according to their individual response and other important factors.
