Kamagra is a medication used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). Its active ingredient is sildenafil citrate, which is also found in Viagra. One of the common side effects of sildenafil and similar medications can be fatigue or tiredness. This side effect isn't experienced by everyone who takes the medication, but it's listed as a potential adverse reaction. If you're experiencing tiredness or any other unusual symptoms after taking Kamagra, it's important to discuss this with your healthcare provider. They can help determine if the medication is causing these symptoms or if there might be another underlying reason. It's also crucial to follow your healthcare provider's instructions regarding dosage and usage of Kamagra to minimize the risk of side effects.
