With reference to the Drug Commission of the German Federal Association of German Pharmacists, the Associations of Pharmacists (ABDA) announced in Berlin that can cause shortness of breath when taking medications containing the active ingredient tamsulosin hcl.
The active ingredient is contained in drugs, which are used for the treatment of prostate diseases. Since especially older women are treated so, they should contact if they experience shortness of breath essential to their doctor or a pharmacy.
A swelling of the upper respiratory tract and larynx is probably the reason for the shortness of breath. The reaction already occurs mostly with the first dose of the drug and upon its discontinuation disappears in a few hours to days.
