Contraindications
Cialis is prohibited in the following cases:
- when taking another medication with nitrate and nitrogen oxides;
- when taking indinavir and ritonavir, used in the treatment of HIV;
- in the presence of ischemic neuropathy of the optic nerve.
Usage of the drug is not recommended in the following cases:
- in the presence of severe diseases of the liver and kidneys (to determine the optimal dosage, consult a doctor);
- in the presence of an anatomical deformation of the penis. In this case, the drug can cause pain;
- after a heart attack or stroke (Cialis can be taken no sooner than six months after a heart attack or stroke. It is necessary to consult a doctor before use);
- after difficult operations (consultation with a doctor is necessary).
Taking Cialis is also contraindicated for men who have recently experienced a stroke and/or myocardial infarction and are told not to engage in any level of physical exertion, including sex. Patients with heart failure or angina are strongly encouraged to consult with a doctor prior to taking Cialis. Administration of the drug is not recommended with concurrent consumption of alcohol or fatty foods. This will not cause any abnormal side effects, whereas drug effectiveness may decrease.
Possible side effects
Side effects occur in rare cases and are associated with individual intolerance to the drug. Some men have noted the following side effects: back pain, increased heartbeat, indigestion, headache, facial redness, nasal congestion, blurred vision, changes in blood pressure, dizziness and muscle pain. In most cases, if one or more of the above symptoms occur, they disappear within a short period of time. If these symptoms last more than a few hours, consult a doctor.
Other contraindications
- Ischemic neuropathy of the optic nerve
- Serious anatomical abnormalities of the penis
- Chronic liver and/or kidney disease
- Rehabilitation after severe operations
The appearance of extreme side effects rarely occurs, but when they do, it is usually in patients who exceed permissible drug dosages, take with incompatible drugs, or ignore other contraindications. These symptoms are usually brief and usually do not last more than a few hours. If side effects persist beyond 24 hours, it is important to consult with a doctor.
Terms and conditions of storage
Cialis should be stored in a dry place inaccessible to children and animals. Before use, check the expiration date (two years from the date of manufacture). Once the expiration date passes, it should not be used.
