Cialis, Levitra, Viagra and Stendra belong to the medicinal class of PDE5 inhibitors. Their action mechanisms and pharmacological properties are very similar. Therefore, all these drugs for the treatment of erectile dysfunction (ED) have the same contraindications.
Cialis, Viagra, Levitra and Stendra can cause hypotension, or enhance the effect of antihypertensive drugs.
Therefore, these drugs for the ED therapy are contraindicated for a simultaneous use with drugs that are used for the treatment of:
Pain in the chest, in particular with nitrates (Gonitro, Isordil or Monoket)
Pulmonary hypertension, such as Adempas guanylate cyclase stimulant.
In case the potential use of nitrates exceeds the risk of hypotension, they can be taken 12, 24 or 48 hours after the use of Stendra, Cialis, Levitra or Viagra (depending on which of these drugs was taken).
These drugs for the treatment of ED are also contraindicated to patients with known hypersensitivity to one or more inactive components that tablets contain, including:
In addition to various inactive ingredients, these potency recovery tablets also contain different basic active ingredients. If a man has previously been diagnosed with an allergy to any medication, he certainly should find out their composition before he starts using tablets to treat ED.
