I've been using Pyrilamne DM 7.5-7.5mg/5ml Oral Liq for a couple of weeks now, and while it's helped with my cough and allergies, I've noticed some side effects that I'm not sure are normal. The description says it can make you feel sleepy, but I've been feeling really groggy and lethargic during the day. I've also experienced some mild hives, which isn't listed as a common side effect. Has anyone else had these issues? Should I be concerned, or is this just part of the deal with this medication?

I think you need to talk to a doctor and ask about getting a different medication. If it's affecting your daily life, it might be a good idea.

I was prescribed something similar and it knocked me out.

I’d suggest making an appointment with your pharmacist about this. They should be able to address your concerns and if needed, adjust your prescription.

I've had a similar experience. The drowsiness was a bit much for me, so I switched to a different antihistamine that doesn't contain Dextromethorphan and Pyrilamine.

Believe it or not, I noticed hives after using it for the first time! But I'm not so sure if it is a side effect or not.

If the side effects are mild, it might just be your body adjusting to the medication. However, if they persist or get worse, it's definitely worth a call to your doctor. Always better to be safe with meds.

Mine itched like crazy and I was wildly disoriented for a while. I went to the ER and they told me I was allergic.

I had no side effects at all, but I'm really sensitive to medications, so it might depend on the individual.
