Who Is More Likely to Experience Side Effects?
Some people have a greater likelihood of developing adverse reactions. These are patients with heart diseases, low blood pressure, or those who do not manage their high blood pressure properly.
Liver or kidney disease patients require additional consultations because some patients have longer periods of drug elimination from the body. Also, older individuals may be more susceptible to the impact of sildenafil.
Dose is one of the factors that play an important role here. Those who seek information about Fildena 100 mg side effects need to know that a higher dose does not always result in better outcomes.
Drug Interactions That Can Increase Side Effects
Fildena can have interactions with certain medicines. Such interactions can make one prone to hypotension and other complications. Nitrates which are used to treat chest pain conditions must never be combined with sildenafil as the interaction leads to life-threatening hypotension.
Certain alpha blockers that are prescribed for blood pressure and prostate problems can increase the risks of dizziness and syncope when combined with sildenafil. Some antiretroviral drugs which are used to treat HIV, fungicidal agents and antibiotics can increase the levels of sildenafil in the blood stream through the impact on its metabolism.
Fildena must never be combined with other ED medications without the prescription of a physician. Alcohol can increase dizziness in those who use sildenafil and make some of the side effects more pronounced.
